Description

Method, Apparatus and Equipment for Determining Charpy Impact Energy Index

技术领域technical field

本申请涉及石油钻采工程技术领域，尤其涉及一种夏比冲击功指标的确定方法、装置及设备。The application relates to the technical field of petroleum drilling and production engineering, and in particular, to a method, device and equipment for determining a Charpy impact energy index.

背景技术Background technique

夏比冲击功是衡量石油管材的重要力学性指标之一，准确的制定石油管材的夏比冲击功指标，可以有效的提高石油管材使用时的安全性。Charpy impact energy is one of the important mechanical indicators for measuring oil pipes. Accurately formulating the Charpy impact energy index of oil pipes can effectively improve the safety of oil pipes in use.

目前，可以根据屈服强度和石油管材的壁厚，确定石油管材的夏比冲击功指标。例如，石油管材的横向承受的最低冲击功大于屈服强度的百分之十。但是，在实际应用中，由于环境会对石油管材造成损伤(腐蚀等)，使得石油管材更易损坏，因此，根据屈服强度和石油管材的壁厚，无法确定有效的夏比冲击功指标，导致石油管材使用的安全性较低。At present, the Charpy impact energy index of the oil pipe can be determined according to the yield strength and the wall thickness of the oil pipe. For example, the minimum impact energy in the transverse direction of an oil pipe is greater than ten percent of the yield strength. However, in practical applications, because the environment will cause damage (corrosion, etc.) to the oil pipe, the oil pipe is more easily damaged. Therefore, according to the yield strength and the wall thickness of the oil pipe, the effective Charpy impact energy index cannot be determined, resulting in oil Pipes are less safe to use.

为了便于理解，首先对本申请实施例所涉及的概念进行说明。For ease of understanding, concepts involved in the embodiments of the present application are first described.

终端设备：是一种具有无线收发功能的设备。终端设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmentedreality，AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备、可穿戴终端设备等。本申请实施例所涉及的终端设备还可以称为终端、用户设备(user equipment，UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。终端设备也可以是固定的或者移动的。Terminal equipment: It is a device with wireless transceiver function. Terminal equipment can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can also be deployed on water (such as ships, etc.); it can also be deployed in the air (such as aircraft, balloons and satellites, etc.). The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, an industrial control (industrial) terminal device. wireless terminal in control), in-vehicle terminal equipment, wireless terminal in self driving, wireless terminal equipment in remote medical, wireless terminal equipment in smart grid, transportation safety ( Wireless terminal equipment in transportation safety, wireless terminal equipment in smart city, wireless terminal equipment in smart home, wearable terminal equipment, etc. The terminal equipment involved in the embodiments of this application may also be referred to as terminal, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, and remote station , remote terminal equipment, mobile equipment, UE terminal equipment, wireless communication equipment, UE proxy or UE device, etc. Terminal devices can also be stationary or mobile.

夏比冲击功指标：夏比冲击功是夏比冲击试验所用的冲击功。其中，夏比冲击功试验是用于测定金属材料韧性的试验。例如，通过试验机举起的摆锤冲击样品，使得样品沿着缺口冲断，并根据摆锤重新升起的高度差，计算样品断裂时吸收的冲击功，样品吸收的冲击功越大，样品的韧性越高。夏比冲击功指标是样品在生产时满足的夏比冲击功。例如，样品在生产时，每个样品的夏比冲击功需要大于夏比冲击功指标。Charpy impact energy index: Charpy impact energy is the impact energy used in the Charpy impact test. Among them, the Charpy impact energy test is a test used to measure the toughness of metal materials. For example, the sample is impacted by the pendulum lifted by the testing machine, so that the sample breaks along the notch, and the impact energy absorbed when the sample is broken is calculated according to the height difference of the pendulum rising again. The greater the impact energy absorbed by the sample, the better the sample higher toughness. The Charpy impact energy index is the Charpy impact energy that the sample satisfies during production. For example, when the samples are produced, the Charpy impact energy of each sample needs to be greater than the Charpy impact energy index.

断裂韧性：断裂韧性是表征材料阻止裂纹扩展的能力，是度量材料的韧性的定量指标。例如，在材料的裂纹尺寸一定时，材料的断裂韧性值越大，材料裂纹失稳扩展所需的临界应力越大，材料的韧性越高；在材料受到的外力一定时，材料的断裂韧性值越大，材料的裂纹达到失稳扩展时的临界尺寸越大。可选的，材料的断裂韧性与材料所处的环境相关。例如，相同的材料在非腐蚀环境下的断裂韧性大于在腐蚀环境下的断裂韧性。Fracture toughness: Fracture toughness characterizes the ability of a material to prevent crack propagation, and is a quantitative indicator for measuring the toughness of a material. For example, when the crack size of the material is constant, the greater the fracture toughness value of the material, the greater the critical stress required for the unstable expansion of the material crack, and the higher the toughness of the material; when the external force on the material is constant, the fracture toughness value of the material is greater. The larger the size, the larger the critical size of the material when the crack reaches the unstable growth. Optionally, the fracture toughness of the material is related to the environment in which the material is exposed. For example, the fracture toughness of the same material in a non-corrosive environment is greater than that in a corrosive environment.

下面，结合图1，对本申请实施例所适用的应用场景进行说明。Below, with reference to FIG. 1 , an application scenario to which the embodiments of the present application are applicable will be described.

图1为本申请实施例提供的应用场景示意图。请参见图1，包括终端设备。终端设备接收到样本的第一断裂韧性，并根据第一断裂韧性确定样品在常温常压下无敏感介质的环境中的第一夏比冲击功指标。终端设备根据第一夏比冲击功指标，确定样品在常温常压下存在敏感介质的环境中的第二断裂韧性，进而根据第一断裂韧性和第二断裂韧性，确定样品在第二环境中的敏感状态。若样品对第二环境不敏感，则终端设备输出第一夏比冲击功指标作为样品在第二环境中的目标夏比冲击功指标，若样品对第二环境敏感，则终端设备根据第一断裂韧性和第二断裂韧性，输出样品在第二环境中的目标夏比冲击功指标。由于第一断裂韧性和第二断裂韧性是相同的样品在不同的环境中测量得到的，因此，根据第一断裂韧性和第二断裂韧性可以准确的反映样品对环境的敏感程度，通过断裂韧性，可以准确的确定样品在不同环境中的夏比冲击功指标，进而可以提高石油管材使用的安全性。FIG. 1 is a schematic diagram of an application scenario provided by an embodiment of the present application. See Figure 1, including terminal equipment. The terminal device receives the first fracture toughness of the sample, and determines, according to the first fracture toughness, the first Charpy impact energy index of the sample in an environment without a sensitive medium at normal temperature and pressure. The terminal equipment determines the second fracture toughness of the sample in the environment where the sensitive medium exists at normal temperature and pressure according to the first Charpy impact energy index, and then determines the sample's second fracture toughness in the second environment according to the first fracture toughness and the second fracture toughness. sensitive state. If the sample is not sensitive to the second environment, the terminal device outputs the first Charpy impact energy index as the target Charpy impact energy index of the sample in the second environment. If the sample is sensitive to the second environment, the terminal device will break according to the first Toughness and Second Fracture Toughness, output the target Charpy impact energy index of the sample in the second environment. Since the first fracture toughness and the second fracture toughness are measured by the same sample in different environments, the sensitivity of the sample to the environment can be accurately reflected according to the first fracture toughness and the second fracture toughness. The Charpy impact energy index of the sample in different environments can be accurately determined, thereby improving the safety of the oil pipe.

在相关技术中，根据石油管材的屈服强度和石油管材的壁厚，确定石油管材的夏比冲击功指标。例如，石油管材的横向承受的最低冲击功大于或等于屈服强度的百分之十。但是，在实际应用中，由于环境会对石油管材造成损伤(腐蚀等)，使得石油管材更易损坏，因此，根据屈服强度和石油管材的壁厚，无法确定有效的夏比冲击功指标，导致石油管材使用的安全性较低。In the related art, according to the yield strength of the oil pipe and the wall thickness of the oil pipe, the Charpy impact energy index of the oil pipe is determined. For example, the minimum impact energy of the oil pipe in the transverse direction is greater than or equal to ten percent of the yield strength. However, in practical applications, because the environment will cause damage (corrosion, etc.) to the oil pipe, the oil pipe is more easily damaged. Therefore, according to the yield strength and the wall thickness of the oil pipe, the effective Charpy impact energy index cannot be determined, resulting in oil Pipes are less safe to use.

为了解决相关技术中石油管材使用的安全性较低的技术问题，本申请实施例提供一种夏比冲击功指标的确定方法，获取石油管材样品在第一环境(常温常压)中的第一断裂韧性，并根据第一断裂韧性，确定石油管材样品在第一环境中的第一夏比冲击功指标。根据第一夏比冲击功指标，确定石油管材样品在第二环境(硫化氢环境)中的第二断裂韧性，并根据第一断裂韧性和第二断裂韧性之间的变化量，确定第二环境对石油管材样品的断裂韧性的影响程度，在第二环境对石油管材样品的断裂韧性的影响较大时，可以结合第一断裂韧性和第二断裂韧性，准确的确定程度样品在第二环境中的断裂韧性阈值，进而可以准确的得到石油管材样品在第二环境中的目标夏比冲击功指标，提高石油管材使用的安全性。In order to solve the technical problem of low safety in the use of petroleum pipe materials in the related art, the embodiment of the present application provides a method for determining the Charpy impact energy index, and obtains the first fracture of the petroleum pipe material sample in the first environment (normal temperature and normal pressure) toughness, and according to the first fracture toughness, determine the first Charpy impact energy index of the oil pipe sample in the first environment. According to the first Charpy impact energy index, the second fracture toughness of the oil pipe sample in the second environment (hydrogen sulfide environment) is determined, and the second environment is determined according to the change between the first fracture toughness and the second fracture toughness The degree of influence on the fracture toughness of the oil pipe sample, when the second environment has a greater impact on the fracture toughness of the oil pipe sample, the first fracture toughness and the second fracture toughness can be combined to accurately determine the degree of the sample in the second environment. Therefore, the target Charpy impact energy index of the oil pipe sample in the second environment can be accurately obtained, and the safety of the use of the oil pipe can be improved.

It should be noted that the following embodiments may exist alone or may be combined with each other, and the same or similar content will not be repeated in different embodiments.

本申请实施例的执行主体可以为终端设备，也可以为设置在终端设备中的夏比冲击功指标的确定装置。可选的，夏比冲击功指标的确定装置可以通过软件实现，也可以通过软件和硬件的结合实现。The execution subject of the embodiment of the present application may be a terminal device, or may be a device for determining a Charpy impact energy index set in the terminal device. Optionally, the device for determining the Charpy impact energy index may be implemented by software, or may be implemented by a combination of software and hardware.

样品可以为需要确定夏比冲击功指标的金属材料。例如，样品可以为石油管材、钢筋等材料。第一环境可以为对样品的断裂韧性没有影响的环境。例如，第一环境可以为常温常压下的环境。The sample can be a metal material that needs to determine the Charpy impact energy index. For example, the samples can be petroleum pipes, steel bars and other materials. The first environment may be an environment that has no effect on the fracture toughness of the sample. For example, the first environment may be an environment at normal temperature and normal pressure.

第一断裂韧性为样品在第一环境中的断裂韧性阈值。例如，石油管材的第一断裂韧性可以为石油管材在常温常压下，且空气中没有腐蚀性气体的环境中的需要达到的最低的断裂韧性。The first fracture toughness is the fracture toughness threshold of the sample in the first environment. For example, the first fracture toughness of the oil pipe material may be the lowest fracture toughness that the oil pipe material needs to achieve under normal temperature and normal pressure and in an environment without corrosive gas in the air.

可选的，可以根据如下可行的实现方式获取样品在第一环境中的第一断裂韧性：根据样品的信息，确定样品在第一环境中的第一断裂韧性。其中，样品的信息包括样品的尺寸、样品的材料。例如，若石油管材的材料为110钢级、外径114.3毫米、内壁12.7毫米，则石油管材在常温差压下，且空气中没有腐蚀性气体的环境中的断裂韧性为大于或等于52.90MPa·m^1/2。Optionally, the first fracture toughness of the sample in the first environment can be acquired according to the following feasible implementation manner: according to the information of the sample, the first fracture toughness of the sample in the first environment is determined. The information of the sample includes the size of the sample and the material of the sample. For example, if the material of the oil pipe is 110 steel grade, the outer diameter is 114.3 mm, and the inner wall is 12.7 mm, the fracture toughness of the oil pipe under normal temperature and differential pressure and in an environment without corrosive gas in the air is greater than or equal to 52.90MPa· m ^1/2 .

可选的，可以根据实验得到样品在第一环境中的第一断裂韧性。例如，可以通过夏比冲击实验，得到多个被不同冲击功撞击后的样品，通过材料万能试验机对多个撞击后的样品的断裂韧性进行测量，将多个断裂韧性的平均值，确定为样品在第一环境中的第一断裂韧性。Optionally, the first fracture toughness of the sample in the first environment can be obtained according to experiments.

For example, the first Charpy impact energy index is the Charpy impact energy index in an environment where the sample is at normal temperature and pressure and there is no corrosive gas in the air. Optionally, the first Charpy impact energy index of the sample in the first environment may be determined according to a first preset relationship between the fracture toughness and the Charpy impact energy index in the first environment. For example, the first preset relationship between the fracture toughness and the Charpy impact energy index in the first environment may be as shown in Table 1:

表1Table 1

需要说明的是，表1只是以示例的形式示意断裂韧性和夏比冲击功指标在第一环境中的第一预设关系，并非对第一环境中断裂韧性和夏比冲击功的对应关系的限定。It should be noted that Table 1 only shows the first preset relationship between fracture toughness and Charpy impact energy in the first environment in the form of an example, not the corresponding relationship between fracture toughness and Charpy impact energy in the first environment. limited.

例如，样品在第一环境中的第一断裂韧性为断裂韧性1时，样品在第一环境中的第一夏比冲击功指标为夏比冲击功指标1；样品在第一环境中的第一断裂韧性为断裂韧性2时，样品在第一环境中的第一夏比冲击功指标为夏比冲击功指标2；样品在第一环境中的第一断裂韧性为断裂韧性3时，样品在第一环境中的第一夏比冲击功指标为夏比冲击功指标3。For example, when the first fracture toughness of the sample in the first environment is fracture toughness 1, the first Charpy impact energy index of the sample in the first environment is Charpy impact energy index 1; When the fracture toughness is fracture toughness 2, the first Charpy impact energy index of the sample in the first environment is Charpy impact energy index 2; when the first fracture toughness of the sample in the first environment is fracture toughness 3, the sample is in the first environment. The first Charpy impact energy index in an environment is Charpy impact energy index 3.

S203、根据第一夏比冲击功指标，确定样品在第二环境中的第二断裂韧性。S203 , determining the second fracture toughness of the sample in the second environment according to the first Charpy impact energy index.

第二环境可以为样品的安装地点的环境。例如，在石油管材安装于空气中存在硫化氢气体的环境中时，第二环境可以为空气中存在硫化氢气体的环境。The second environment may be the environment of the installation site of the sample. For example, when the oil pipe is installed in an environment in which hydrogen sulfide gas exists in the air, the second environment may be an environment in which hydrogen sulfide gas exists in the air.

第二断裂韧性为样品在第二环境中的断裂韧性。例如，石油管材的第二断裂韧性可以为石油管材在低温低压下，且空气中存在腐蚀性气体的环境中的断裂韧性。The second fracture toughness is the fracture toughness of the sample in the second environment. For example, the second fracture toughness of the oil pipe material may be the fracture toughness of the oil pipe material under low temperature and low pressure and in an environment where corrosive gas exists in the air.

可选的，可以根据如下可行的实现方式确定样品在第二环境中的第二断裂韧性：获取断裂韧性和夏比冲击功指标在第二环境中的第二预设关系。其中，第二预设关系中包括至少一个断裂韧性和每个断裂韧性对应的夏比冲击功指标。例如，断裂韧性和夏比冲击功指标在第二环境中的第二预设关系可以如表2所示：Optionally, the second fracture toughness of the sample in the second environment may be determined according to the following feasible implementation manner: obtaining a second preset relationship between the fracture toughness and the Charpy impact energy index in the second environment. Wherein, the second preset relationship includes at least one fracture toughness and a Charpy impact energy index corresponding to each fracture toughness. For example, the second preset relationship between the fracture toughness and the Charpy impact energy index in the second environment may be as shown in Table 2:

表2Table 2

夏比冲击功指标Charpy Impact Energy Index 断裂韧性fracture toughness 夏比冲击功指标1Charpy Impact Energy Index 1 断裂韧性1Fracture toughness1 夏比冲击功指标2Charpy Impact Energy Index 2 断裂韧性2Fracture toughness 2 夏比冲击功指标3Charpy Impact Energy Index 3 断裂韧性3Fracture toughness3 ……... ……...

需要说明的是，表2只是以示例的形式示意断裂韧性和夏比冲击功指标在第二环境中的第二预设关系，并非对断裂韧性和夏比冲击功指标在第二环境中的第二预设关系的限定。It should be noted that Table 2 only shows the second preset relationship between the fracture toughness and the Charpy impact energy index in the second environment in the form of an example, not the first relationship between the fracture toughness and the Charpy impact energy index in the second environment. 2. The limitation of the preset relationship.

根据第一夏比冲击功指标和第二预设关系，确定样品在第二环境中的第二断裂韧性。例如，在样品的第一夏比冲击功指标为夏比冲击功指标1时，样品在第二环境中的第二断裂韧性为断裂韧性1；在样品的第一夏比冲击功指标为夏比冲击功指标2时，样品在第二环境中的第二断裂韧性为断裂韧性2；在样品的第一夏比冲击功指标为夏比冲击功指标3时，样品在第二环境中的第二断裂韧性为断裂韧性3。According to the first Charpy impact energy index and the second preset relationship, the second fracture toughness of the sample in the second environment is determined. For example, when the first Charpy impact energy index of the sample is Charpy impact energy index 1, the second fracture toughness of the sample in the second environment is fracture toughness 1; when the first Charpy impact energy index of the sample is Charpy When the impact energy index is 2, the second fracture toughness of the sample in the second environment is fracture toughness 2; when the first Charpy impact energy index of the sample is Charpy impact energy index 3, the second fracture toughness of the sample in the second environment is Fracture toughness is Fracture Toughness 3.

S204、根据第一断裂韧性和第二断裂韧性，确定样品在第二环境中的敏感状态。S204. Determine the sensitive state of the sample in the second environment according to the first fracture toughness and the second fracture toughness.

敏感状态用于指示第二环境是否对样品的断裂韧性造成影响。可选的，敏感状态可以为敏感或不敏感。例如，在样品对第二环境的敏感状态为敏感时，第二环境对样品的断裂韧性造成影响时，在样品对环境的敏感状态为不敏感时，第二环境对样品的断裂韧性不造成影响。The sensitive state is used to indicate whether the second environment has an effect on the fracture toughness of the sample. Optionally, the sensitive state can be sensitive or insensitive. For example, when the sensitive state of the sample to the second environment is sensitive and the second environment affects the fracture toughness of the sample, when the sensitive state of the sample to the environment is insensitive, the second environment does not affect the fracture toughness of the sample .

可选的，可以根据如下可行的实现方式，确定样品在第二环境中的敏感状态：根据第一断裂韧性和第二断裂韧性，确定样品对第二环境的敏感指数。其中，敏感指数用于指示样品对第二环境的敏感程度。可选的，样品在第二环境中的敏感状态为敏感时，样品对第二环境的敏感程度越高，第二环境对样品的断裂韧性影响越大。例如，在样品对第二环境的敏感程度较高时，第二环境对样品的断裂韧性影响较大，在样品对第二环境的敏感程度较低时，第二环境对样品的断裂韧性影响较小。Optionally, the sensitivity state of the sample in the second environment may be determined according to the following feasible implementation manner: determining the sensitivity index of the sample to the second environment according to the first fracture toughness and the second fracture toughness. The sensitivity index is used to indicate the sensitivity of the sample to the second environment. Optionally, when the sensitive state of the sample in the second environment is sensitive, the higher the sensitivity of the sample to the second environment, the greater the influence of the second environment on the fracture toughness of the sample. For example, when the sensitivity of the sample to the second environment is high, the second environment has a greater impact on the fracture toughness of the sample, and when the sensitivity of the sample to the second environment is low, the second environment has a greater impact on the fracture toughness of the sample. Small.

根据敏感指数，确定样品在第二环境中的敏感状态。可选的，在敏感指数小于或等于第一阈值时，将样品的环境敏感状态确定为不敏感；在敏感指数大于第一阈值时，将样品的环境敏感状态确定为敏感。例如，在敏感指数小于或等于第一阈值时，说明相对于第一环境中的断裂韧性，样品第二环境中的断裂韧性变化较小，第二环境不会对样品的断裂韧性造成影响；在敏感指数大于第一阈值时，说明相对于第一环境中的断裂韧性，样品第二环境中的断裂韧性变化较大，第二环境会对样品的断裂韧性造成影响。According to the sensitivity index, the sensitive state of the sample in the second environment is determined. Optionally, when the sensitivity index is less than or equal to the first threshold, the environmentally sensitive state of the sample is determined to be insensitive; when the sensitivity index is greater than the first threshold, the environmentally sensitive state of the sample is determined to be sensitive. For example, when the sensitivity index is less than or equal to the first threshold, it means that the fracture toughness of the sample in the second environment changes relatively little compared to the fracture toughness in the first environment, and the second environment will not affect the fracture toughness of the sample; in When the sensitivity index is greater than the first threshold, it means that the fracture toughness of the sample in the second environment changes greatly relative to the fracture toughness in the first environment, and the second environment will affect the fracture toughness of the sample.

可选的，可以根据如下公式，确定样品对第二环境的敏感指数：Optionally, the sensitivity index of the sample to the second environment can be determined according to the following formula:

k＝(K_IC-K_ISSC)/K_IC k=(K _IC -K _ISSC )/K _IC

其中，k为样品对第二环境的敏感指数；K_IC为样品在第一环境中的第一断裂韧性；K_ISSC为样品在第二环境中的第二断裂韧性。Wherein, k is the sensitivity index of the sample to the second environment; K _IC is the first fracture toughness of the sample in the first environment; K _ISSC is the second fracture toughness of the sample in the second environment.

例如，若样品在第一环境中的第一断裂韧性为50MPa·m^1/2，样品在第二环境中的第二断裂韧性为20MPa·m^1/2，则样品对第二环境的敏感指数为60％，说明相比于第一环境，第二环境对样品的断裂韧性影响较大；若样品在第一环境中的第一断裂韧性与样品在第二环境中的第二断裂韧性相同，则样品对第二环境的敏感指数为零，说明相比于第一环境，第二环境不会影响样品的断裂韧性。For example, if the first fracture toughness of the sample in the first environment is 50MPa·m ^1/2 and the second fracture toughness of the sample in the second environment is 20MPa·m ^1/2 , then the sensitivity index of the sample to the second environment is 60%, indicating that compared with the first environment, the second environment has a greater impact on the fracture toughness of the sample; if the first fracture toughness of the sample in the first environment is the same as the second fracture toughness of the sample in the second environment, Then the sensitivity index of the sample to the second environment is zero, indicating that compared with the first environment, the second environment does not affect the fracture toughness of the sample.

S205、根据敏感状态、第一夏比冲击功指标、第一断裂韧性、第二断裂韧性，确定样品在所述第二环境中的目标夏比冲击功指标。S205 , according to the sensitive state, the first Charpy impact energy index, the first fracture toughness, and the second fracture toughness, determine the target Charpy impact energy index of the sample in the second environment.

目标夏比冲击功指标可以为样品在第二环境中的夏比冲击功指标。例如，目标夏比冲击功指标为样品在低温低压下，且空气中存在腐蚀性气体的环境中的夏比冲击功指标。The target Charpy impact energy index may be the Charpy impact energy index of the sample in the second environment. For example, the target Charpy impact energy index is the Charpy impact energy index in an environment where the sample is at low temperature and low pressure and corrosive gas exists in the air.

根据敏感状态、第一夏比冲击功指标、第一断裂韧性、第二断裂韧性，确定样品在所述第二环境中的目标夏比冲击功指标，有如下两种情况：According to the sensitive state, the first Charpy impact energy index, the first fracture toughness, and the second fracture toughness, the target Charpy impact energy index of the sample in the second environment is determined, and there are two situations as follows:

情况1：样品在第二环境中的敏感状态为不敏感。Case 1: The sensitive state of the sample in the second environment is insensitive.

样品在第二环境中的敏感状态为不敏感时，可以将第一夏比冲击功指标，确定为样品在第二环境中的目标夏比冲击功指标。例如，在获取样品在第一环境中的断裂韧性时，根据第一预设关系，可以确定样品在第一环境中的第一夏比冲击功指标，若相比于第一环境，第二环境不会影响样品的断裂韧性，则可以将第一环境中样品的第一夏比冲击功指标，确定为样品在第二环境中的目标夏比冲击功指标。When the sensitive state of the sample in the second environment is insensitive, the first Charpy impact energy index may be determined as the target Charpy impact energy index of the sample in the second environment. For example, when obtaining the fracture toughness of the sample in the first environment, according to the first preset relationship, the first Charpy impact energy index of the sample in the first environment can be determined. If compared with the first environment, the second environment If the fracture toughness of the sample is not affected, the first Charpy impact energy index of the sample in the first environment can be determined as the target Charpy impact energy index of the sample in the second environment.

在该种情况中，由于相比于第一环境，第二环境不会对样品的断裂韧性造成影响，因此，样品在第一环境和第二环境中的断裂韧性相同，进而可以将样品在第一环境中的第一夏比冲击功指标，确定为样品在第二环境中的第二夏比冲击功指标，进而可以提高确定样品的夏比冲击功指标的准确度，提高了样品使用时的安全性。In this case, since the second environment does not affect the fracture toughness of the sample compared with the first environment, the fracture toughness of the sample in the first environment and the second environment is the same, and the sample can be placed in the first environment. The first Charpy impact energy index in the first environment is determined as the second Charpy impact energy index of the sample in the second environment, so that the accuracy of determining the Charpy impact energy index of the sample can be improved, and the use of the sample can be improved. safety.

情况2：样品在第二环境中的敏感状态为敏感。Case 2: The sensitive state of the sample in the second environment is sensitive.

样品在第二环境中的敏感状态为敏感时，根据第一断裂韧性、第二断裂韧性，确定样品在第二环境中的目标夏比冲击功指标。例如，若相比于第一环境，第二环境会影响样品的断裂韧性，则可以根据第一断裂韧性和第二断裂韧性，确定样品在第二环境中的断裂韧性阈值，根据断裂韧性阈值，确定样品在第二环境中的目标夏比冲击功指标。When the sensitive state of the sample in the second environment is sensitive, the target Charpy impact energy index of the sample in the second environment is determined according to the first fracture toughness and the second fracture toughness. For example, if the second environment affects the fracture toughness of the sample compared to the first environment, the fracture toughness threshold of the sample in the second environment can be determined according to the first fracture toughness and the second fracture toughness. According to the fracture toughness threshold, A target Charpy impact energy index for the sample in the second environment is determined.

在该种情况中，由于相比于第一环境，第二环境会对样品的断裂韧性造成影响，因此，可以根据第一环境中的第一断裂韧性和第一夏比冲击功指标在第二环境中对应的第二断裂韧性，确定样品在第二环境中的断裂韧性阈值，进而根据断裂韧性阈值，可以准确的确定样品在第二环境中的目标夏比冲击功指标，提高了样品使用时的安全性。In this case, since the second environment will affect the fracture toughness of the sample compared to the first environment, the second environment can be calculated according to the first fracture toughness and the first Charpy impact energy index in the first environment The corresponding second fracture toughness in the environment is used to determine the fracture toughness threshold of the sample in the second environment, and then according to the fracture toughness threshold, the target Charpy impact energy index of the sample in the second environment can be accurately determined, which improves the use of the sample. security.

When the sensitive state of the sample in the second environment is sensitive, determine the fracture toughness threshold of the sample in the second environment according to the first fracture toughness and the second fracture toughness.

断裂韧性阈值为样品在第二环境中要求的最低断裂韧性。例如，在生产石油管材时，若石油管材的安装地点为空气中存在硫化氢的地点，则石油管材的断裂韧性需要大于或等于断裂韧性阈值。The fracture toughness threshold is the minimum fracture toughness required for the sample in the second environment.

可选的，可以根据如下公式，确定样品在第二环境中的断裂韧性阈值：Optionally, the fracture toughness threshold of the sample in the second environment can be determined according to the following formula:

K′_IC＝K_IC(1+(K_IC-K_ISSC)/K_IC)K' _IC = K _IC (1+(K _IC -K _ISSC )/K _IC )

其中，K′_IC为样品在第二环境中的断裂韧性阈值，K_IC为样品在第一环境中的第一断裂韧性；K_ISSC为样品在第二环境中的第二断裂韧性。Wherein, K′ _IC is the fracture toughness threshold of the sample in the second environment, K _IC is the first fracture toughness of the sample in the first environment; K _ISSC is the second fracture toughness of the sample in the second environment.

The samples are petroleum pipes with grade 110 steel, outer diameter of 114.3 mm, inner wall of 12.7 mm, and super 13Cr. Optionally, the model of the box-type resistance furnace is SMT-10-12A, and the model of the pendulum impact testing machine is ZBC2302-C.

其中，K_IC为断裂韧性；R_t0.6为屈服强度；A_KV为夏比冲击功。Among them, K _IC is fracture toughness; R _t0.6 is yield strength; A _KV is Charpy impact energy.

根据常温常压下对石油管材的使用要求，给定110钢级、外径114.3毫米、内壁12.7毫米、超级13Cr的石油管材在第一环境中的第一断裂韧性为52.9MPa·m^1/2，110钢级的屈服强度为758MPa，根据模型可以得到石油管材在第一环境中的第一夏比冲击功指标为90J。According to the requirements for the use of petroleum pipes under normal temperature and pressure, the first fracture toughness in the first environment is 52.9MPa m ^1/2 for the petroleum pipes with grade 110, outer diameter of 114.3 mm, inner wall of 12.7 mm and super 13Cr. , the yield strength of 110 steel grade is 758MPa, and according to the model, the first Charpy impact energy index of the oil pipe in the first environment is 90J.

采用NACE 0177标准的D法，可以测得第二环境中的石油管材的断裂韧性，并建立第二环境中夏比冲击功和断裂韧性的对应关系。根据第一夏比冲击功指标为90J，将其带入第二环境中夏比冲击功和断裂韧性的对应关系，可以得到夏比冲击功为90J的石油管材在硫化氢的环境中的断裂韧性为33.90MPa·m^1/2。Using the D method of the NACE 0177 standard, the fracture toughness of oil pipes in the second environment can be measured, and the corresponding relationship between Charpy impact energy and fracture toughness in the second environment can be established. According to the first Charpy impact energy index of 90J, taking it into the corresponding relationship between Charpy impact energy and fracture toughness in the second environment, the fracture toughness of petroleum pipes with Charpy impact energy of 90J in the hydrogen sulfide environment can be obtained. It is 33.90MPa·m ^1/2 .

According to the fracture toughness threshold and the mathematical model of Charpy impact energy and fracture toughness, it can be obtained that the Charpy impact energy index of the oil pipe in the second environment is 140J, that is, the Charpy impact energy of the produced oil pipe needs to be treated 140J. In this way, the first fracture toughness and the second fracture toughness of the oil pipe in different environments can be combined to accurately determine whether the oil pipe is sensitive to the second environment. When the oil pipe is sensitive to the second environment, according to the first fracture toughness and the second Fracture toughness can accurately determine the fracture toughness threshold of the sample in the second environment, and then obtain an accurate target Charpy impact energy index, which improves the safety of oil pipe materials.
