技术领域Technical Field
本发明涉及钻井液液位测量领域，具体地，涉及一种钻井液液位测量装置及测量方法。The present invention relates to the field of drilling fluid level measurement, and in particular to a drilling fluid level measurement device and a measurement method.
背景技术Background technique
钻井液是钻井过程中以其多种功能满足钻井工作需要的各种循环流体总称。钻井液是钻井的血液，又称钻孔冲洗液。Drilling fluid is the general term for various circulating fluids that meet the needs of drilling work with its multiple functions during the drilling process. Drilling fluid is the blood of drilling, also known as drilling flushing fluid.
钻井液对于钻井过程很重要，钻井液将钻井过程中的杂质从井底带出，主要作用是把岩屑从井底携带至地面，钻井液的液位比较重要需要实时监测，比如液位突然上升可能出现地下水，或钻井液液位突然下降可能遇到地下洞穴等等，因此，钻井液的液位需要实时监测。Drilling fluid is very important to the drilling process. Drilling fluid brings out impurities from the bottom of the well during the drilling process. Its main function is to carry cuttings from the bottom of the well to the surface. The liquid level of the drilling fluid is important and needs to be monitored in real time. For example, if the liquid level suddenly Groundwater may rise, or a sudden drop in drilling fluid level may encounter underground caves, etc. Therefore, the drilling fluid level needs to be monitored in real time.
在现有技术中，钻井液的液位测量是在钻井液池中安装液位传感器进行测量，但是申请人发现随着泡沫钻井液的逐渐推广，与常规钻井液体系相比，泡沫钻井液中泡沫的流体密度较低，因此可以减少静液柱压力，降低漏失的发生，因此泡沫钻井液的应用逐渐广泛，但是传统的这种液位测量方式并不适合钻井液为泡沫钻井液，由于泡沫钻井液中含有较多的气泡，导致使用传统的测压式的液位传感器来测量泡沫钻井液的液位则会出现测量不准确的情况。In the prior art, the liquid level of drilling fluid is measured by installing a liquid level sensor in the drilling fluid pool. However, the applicant found that with the gradual promotion of foam drilling fluid, compared with the conventional drilling fluid system, the content of the liquid level in the foam drilling fluid The fluid density of foam is low, so it can reduce the hydrostatic column pressure and reduce the occurrence of leakage. Therefore, the application of foam drilling fluid is gradually widespread. However, this traditional liquid level measurement method is not suitable for drilling fluids. Foam drilling fluids are used because of the foam. Drilling fluid contains a lot of bubbles, which leads to inaccurate measurement when using traditional pressure measuring liquid level sensors to measure the level of foam drilling fluid.
发明内容Contents of the invention
本发明目的是能够针对不同类型的钻井液实现其液位的准确测量。The purpose of the invention is to be able to achieve accurate measurement of liquid levels of different types of drilling fluids.
为实现上述目的，本发明提供了一种钻井液液位测量装置，所述装置包括：In order to achieve the above object, the present invention provides a drilling fluid level measuring device, which includes:
采集单元，用于获得钻井液的类型信息；Collection unit, used to obtain drilling fluid type information;
判断单元，用于基于所述类型信息判断钻井液是否为泡沫钻井液，若是则开启第一液位测量单元，若否则开启第二液位测量单元；A judgment unit configured to judge whether the drilling fluid is foam drilling fluid based on the type information, and if so, turn on the first liquid level measurement unit; if not, turn on the second liquid level measurement unit;
第一液位测量单元，用于将发光体安装在钻井液池中，拍摄发光体与钻井液液面接触部分的图像，分析所述图像并基于发光体表面的刻度获得钻井液池的钻井液液位信息；The first liquid level measuring unit is used to install the luminous body in the drilling fluid pool, take an image of the contact part between the luminous body and the drilling fluid surface, analyze the image and obtain the drilling fluid in the drilling fluid pool based on the scale on the surface of the luminous body. Liquid level information;
第二液位测量单元，用于将液位传感器安装在钻井液池中，基于液位传感器获得钻井液池的钻井液液位信息。The second liquid level measurement unit is used to install a liquid level sensor in the drilling fluid pool and obtain drilling fluid level information of the drilling fluid pool based on the liquid level sensor.
其中，本装置首先利用采集单元获得钻井液的类型信息，获得钻井液的类型目的是根据不同的类型采用不同的液位测量方式进行测量，避免传统采用单一的测量方式，导致无法对泡沫钻井液进行准确液位测量的问题，当钻井液为泡沫钻井液时，传统的压力式液位测量传感器则会出现测量不准确的情况，本装置利用第一液位测量单元实现对泡沫钻井液的液位的准确测量，第一液位测量单元的测量原理为：将发光体安装在钻井液池中，拍摄发光体与钻井液液面接触部分的图像，分析所述图像并基于发光体表面的刻度获得钻井液池的钻井液液位信息，即通过拍摄液位图像然后分析液位的刻度获得实际的液位信息，由于钻井液比较浑浊不易观察，且为了便于在夜间拍摄和识别，设计了发光体，利用发光体发光便于准确从图像中分析出液位。当钻井液为非泡沫钻井液时，则将液位传感器安装在钻井液池中，基于液位传感器获得钻井液池的钻井液液位信息。通过上述2种液位测量单元可以针对不同类型的钻井液开启相应的液位测量单元完成钻井液液位测量。Among them, this device first uses the acquisition unit to obtain the type information of the drilling fluid. The purpose of obtaining the type of drilling fluid is to use different liquid level measurement methods according to different types to avoid the traditional use of a single measurement method, which results in the inability to measure the foam drilling fluid. The problem of accurate liquid level measurement is that when the drilling fluid is foam drilling fluid, the traditional pressure level measurement sensor will have inaccurate measurements. This device uses the first liquid level measurement unit to achieve liquid level measurement of foam drilling fluid. For accurate measurement of liquid level, the measurement principle of the first liquid level measurement unit is as follows: install the luminous body in the drilling fluid pool, take an image of the contact part between the luminous body and the drilling fluid surface, analyze the image and calculate the scale based on the surface of the luminous body Obtain the drilling fluid level information of the drilling fluid pool, that is, obtain the actual liquid level information by taking the liquid level image and then analyzing the liquid level scale. Because the drilling fluid is relatively turbid and difficult to observe, and in order to facilitate shooting and identification at night, a luminous device is designed The liquid level can be accurately analyzed from the image by using the luminous body to emit light. When the drilling fluid is non-foam drilling fluid, a liquid level sensor is installed in the drilling fluid pool, and the drilling fluid level information of the drilling fluid pool is obtained based on the liquid level sensor. Through the above two types of liquid level measurement units, corresponding liquid level measurement units can be turned on for different types of drilling fluids to complete drilling fluid level measurement.
其中，在一些实施例中，所述第一液位测量单元包括：Wherein, in some embodiments, the first liquid level measurement unit includes:
悬挂机构、伸缩机构、发光体、图像采集模块和分析模块；Suspension mechanism, telescopic mechanism, luminous body, image acquisition module and analysis module;
悬挂机构用于悬挂在钻井液池液面上方，伸缩机构与所述悬挂机构连接，伸缩机构与发光体上端连接，初始测量时，发光体下端延伸至钻井液池底部，伸缩机构用于调整发光体在钻井液池中的位置，图像采集模块用于拍摄发光体与钻井液液面接触部分的图像，分析模块用于分析所述图像并基于发光体表面的刻度获得钻井液池的钻井液液位信息。The suspension mechanism is used to be suspended above the liquid surface of the drilling fluid pool, the telescopic mechanism is connected to the suspension mechanism, and the telescopic mechanism is connected to the upper end of the light-emitting body. During initial measurement, the lower end of the light-emitting body extends to the bottom of the drilling fluid pool. The telescopic mechanism is used to adjust the position of the light-emitting body in the drilling fluid pool. The image acquisition module is used to capture an image of the contact portion between the light-emitting body and the drilling fluid surface, and the analysis module is used to analyze the image and obtain the drilling fluid level information of the drilling fluid pool based on the scale on the surface of the light-emitting body.
其中，利用悬挂机构可以将第一液位测量单元的部分机构悬挂在钻井液池液面上方，利用伸缩机构的伸缩功能方便调整发光体伸入钻井液池的深度，便于在初始测量时，发光体下端延伸至钻井液池底部，这样才能够测量出准确的液位，以及在使用一段时间后钻井液池底部出现一层淤泥层，则利用伸缩机构将发光体向上移动一段距离脱离淤泥层，利用图像采集模块和分析模块的配合实现图像采集与分析功能最终实现获得钻井液池的钻井液液位信息。Among them, the suspension mechanism can be used to hang part of the first liquid level measurement unit above the liquid level of the drilling fluid pool, and the telescopic function of the telescopic mechanism can be used to conveniently adjust the depth of the luminous body extending into the drilling fluid pool, so that the light can be emitted during the initial measurement. The lower end of the body extends to the bottom of the drilling fluid pool, so that the accurate liquid level can be measured. If a layer of silt appears at the bottom of the drilling fluid pool after being used for a period of time, the telescopic mechanism will be used to move the luminous body upward a certain distance away from the silt layer. The image acquisition and analysis functions are realized through the cooperation of the image acquisition module and the analysis module, and finally the drilling fluid level information of the drilling fluid pool is obtained.
其中，在一些实施例中，申请人研究发现，由于钻井液的作用是把岩屑从井底携带至地面，因此钻井液中含有较多的杂质，在循环使用的过程中很容易沉积在钻井液池中，导致钻井液池底部出现一层淤泥层，而在初始测量时，发光体下端延伸至钻井液池底部，这时当钻井液池底部已经出现一层淤泥层后仍然保持当前的状态进行液位测量则会由于淤泥层的影响导致液位测量不准确，因此，本发明进行了如下设计，对发光体进行了改进，通过改进后的发光体能够测量钻井液池底部是否有淤泥层以及淤泥层的厚度，进而根据淤泥层的厚度调整发光体的上移距离，进而准确的实现钻井液的液位测量。Among them, in some embodiments, the applicant's research found that since the function of the drilling fluid is to carry rock cuttings from the bottom of the well to the ground, the drilling fluid contains more impurities, which are easily deposited in the drilling fluid pool during the recycling process, resulting in a silt layer at the bottom of the drilling fluid pool. During the initial measurement, the lower end of the light-emitting body extends to the bottom of the drilling fluid pool. At this time, when a silt layer has appeared at the bottom of the drilling fluid pool, if the current state is maintained for liquid level measurement, the liquid level measurement will be inaccurate due to the influence of the silt layer. Therefore, the present invention has the following design, and the light-emitting body has been improved. The improved light-emitting body can measure whether there is a silt layer at the bottom of the drilling fluid pool and the thickness of the silt layer, and then adjust the upward movement distance of the light-emitting body according to the thickness of the silt layer, thereby accurately realizing the liquid level measurement of the drilling fluid.
所述发光体包括：The luminous body includes:
柱体和若干软质条带，若干软质条带沿柱体顶端至底端均匀分布在柱体上，软质条带一端与柱体表面固定连接，软质条带另一端用于随钻井液流动而摆动，软质条带和柱体上均匀分布有多个发光元件。A cylinder and a number of soft strips. A number of soft strips are evenly distributed on the column from the top to the bottom of the column. One end of the soft strip is fixedly connected to the surface of the column, and the other end of the soft strip is used for drilling while drilling. The liquid flows and oscillates, and multiple light-emitting elements are evenly distributed on the soft strips and cylinders.
其中，本发明在柱体表面设计多个软质条带的目的是检测是否有淤泥层，钻井液池中的钻井液处于循环流动状态，因为正常情况下软质条带会由于流动钻井液的原因而出现摆动的情况，而当软质条带位于淤泥中时，则其会由于淤泥的原因则会无法随着钻井液的流动而摆动，并且位于淤泥中会导致软质条带上的发光元件部分光线被淤泥阻挡，导致其发射出的光线强度降低。因此可以通过检测软质条带是否随着钻井液摆动以及其光线强度来检测软质条带是否被淤泥覆盖，进而实现钻井液池底部是否有淤泥以及淤泥的厚度检测，淤泥的厚度可以通过位于淤泥层中的软质条带的位置信息来计算获得。如当有三根软质条带位于淤泥中时，则基于最上跟位于淤泥中的软质条带对应的刻度获得淤泥层的厚度。Among them, the purpose of designing multiple soft strips on the surface of the cylinder in the present invention is to detect whether there is a silt layer. The drilling fluid in the drilling fluid pool is in a circulating flow state, because under normal circumstances, the soft strips will be caused by the flow of the drilling fluid. The soft strip will swing due to the mud, and when the soft strip is located in the mud, it will not be able to swing with the flow of drilling fluid due to the mud, and being in the mud will cause the soft strip to glow. Part of the light from the component is blocked by the silt, resulting in a reduction in the intensity of the light it emits. Therefore, it is possible to detect whether the soft strip is covered with silt by detecting whether the soft strip swings with the drilling fluid and its light intensity, thereby detecting whether there is silt at the bottom of the drilling fluid pool and the thickness of the silt. The thickness of the silt can be detected by The position information of the soft strip in the silt layer is calculated and obtained. For example, when there are three soft strips located in the silt, the thickness of the silt layer is obtained based on the scale corresponding to the uppermost soft strip located in the silt.
其中，在一些实施例中，所述图像采集模块还用于在第一预设时间段内连续采集多个发光体的图像获得第一图像集，其中，采集多个连续的图像的目的是通过多个连续的图像判断软质条带是否随着钻井液的流动而摆动，若是则该钻井液可判断没有在淤泥中，若否则判断该钻井液位于淤泥中，所述分析模块还用于分析所述第一图像集判断是否有软质条带位于淤泥层中，若判断出有软质条带位于淤泥层中，则基于位于淤泥层中的软质条带的位置信息获得淤泥层的第一厚度，基于第一厚度伸缩机构将发光体向上抬起第一距离，其中，第一距离的大小等于第一厚度的大小。Wherein, in some embodiments, the image acquisition module is also used to continuously collect images of multiple luminous objects within a first preset time period to obtain the first image set, wherein the purpose of collecting multiple continuous images is to Multiple consecutive images are used to determine whether the soft strips swing with the flow of drilling fluid. If so, the drilling fluid can be judged not to be in the mud. If not, the drilling fluid can be judged to be in the mud. The analysis module is also used to analyze The first image set determines whether there are soft strips located in the silt layer. If it is determined that there are soft strips located in the silt layer, the third image of the silt layer is obtained based on the position information of the soft strips located in the silt layer. A thickness, based on the first thickness telescopic mechanism, the luminous body is lifted upward by a first distance, wherein the size of the first distance is equal to the size of the first thickness.
其中，位于淤泥层中的软质条带的位置信息可以通过图像识别分析获得，通过识别出图像中的软质条带及其对应的刻度信息则可以获得软质条带的位置信息，基于位于淤泥层中的软质条带的位置信息获得淤泥层的第一厚度，基于第一厚度伸缩机构将发光体向上抬起第一距离，目的是将发光体插入淤泥中的部分移出淤泥层使得液位测量准确，其中，第一距离的大小等于第一厚度的大小，这样设计的目的是使得发光体移动的距离等于淤泥层的厚度，避免移动少了有部分发光体仍然在淤泥层中，以及移多了导致发光体下端距离淤泥层仍然有一段距离导致液位测量不准确。Among them, the position information of the soft strip located in the silt layer can be obtained through image recognition analysis, and the position information of the soft strip can be obtained by identifying the soft strip in the image and its corresponding scale information. The first thickness of the silt layer is obtained based on the position information of the soft strip located in the silt layer, and the light-emitting body is lifted up by a first distance based on the first thickness telescopic mechanism, with the purpose of moving the part of the light-emitting body inserted into the silt out of the silt layer to make the liquid level measurement accurate. Among them, the size of the first distance is equal to the size of the first thickness. The purpose of such design is to make the distance moved by the light-emitting body equal to the thickness of the silt layer, to avoid moving less and part of the light-emitting body still in the silt layer, and moving more and causing the lower end of the light-emitting body to be still a distance away from the silt layer, resulting in inaccurate liquid level measurement.
其中，在一些实施例中，所述分析模块分析所述第一图像集判断是否有软质条带位于淤泥层中的具体方式为：In some embodiments, the specific way for the analysis module to analyze the first image set to determine whether there are soft strips located in the silt layer is:
标记出第一图像集中每个图像中每个软质条带的位置和形态，并获得第一图像集中每个图像中每个软质条带的发光亮度，针对多个连续图像，获得每个软质条带的位置变化信息和形态变化信息，若某个软质条带的位置和形态均没有变化且发光亮度小于亮度阈值，则判断该软质条带位于淤泥层中。Mark the position and shape of each soft strip in each image in the first image set, and obtain the luminous brightness of each soft strip in each image in the first image set. For multiple consecutive images, obtain each Position change information and morphological change information of soft strips. If the position and shape of a soft strip do not change and the luminous brightness is less than the brightness threshold, it is judged that the soft strip is located in the silt layer.
其中，位于淤泥层中的软质条带由于淤泥的作用使得其无法随着钻井液的流动而摆动，并且其发出的光线部分会被淤泥层阻挡，导致其在图像中的光线强度会减弱，因此，可以利用多个图像中的软质条带的位置变化信息和形态变化信息来判断其是否随着钻井液的流动而摆动，并根据其的发光亮度来最终综合判断其是否在淤泥层中。Among them, the soft strips located in the silt layer cannot swing with the flow of drilling fluid due to the silt, and part of the light they emit is blocked by the silt layer, resulting in a weakening of the light intensity in the image. Therefore, the position change information and morphological change information of the soft strip in multiple images can be used to determine whether it swings with the flow of drilling fluid, and based on its luminous brightness, it can be finally comprehensively determined whether it is in the silt layer. .
其中，在一些实施例中，第二液位测量单元包括：Wherein, in some embodiments, the second liquid level measurement unit includes:

第二液位传感器与比较电路连接，比较电路与放大电路连接，放大电路与钻井液池的排水装置控制器连接。The second liquid level sensor is connected to the comparison circuit, the comparison circuit is connected to the amplifier circuit, and the amplifier circuit is connected to the drainage device controller of the drilling fluid pool.
其中，第一液位传感器用于测量实时液位，并将测量的液位信息传递给DA模块将数字信号转换为模拟信号，然后将模拟信号传递给单片机进行处理，然后将处理后的信息传递给AD模块将模拟信号转换为数字信号，然后显示屏对数字信号进行显示。Among them, the first liquid level sensor is used to measure the real-time liquid level, and transmits the measured liquid level information to the DA module to convert the digital signal into an analog signal, and then transmits the analog signal to the microcontroller for processing, and then transmits the processed information The AD module converts the analog signal into a digital signal, and then the display screen displays the digital signal.
其中，第二液位传感器与第一电阻R1的一端连接，第一电阻R1的一端与第二电阻R2的一端连接，第一电阻R1的另一端和第二电阻R2的另一端均接地，电压比较器的正输入端连接在第一电阻R1的一端与第二电阻R2的一端之间，第三电阻R3的一端与第四电阻R4的一端连接，第三电阻R3的另一端和第四电阻R4的另一端均接地，电压比较器的负输入端连接在第三电阻R3的一端与第四电阻R4的一端之间，电压比较器的输出端与放大器的正输入端连接，放大器的负输入端接地，放大器的输出端与排水装置的控制器连接，通过上述方式可以利用第二液位传感器测量获得液位信息，然后将测量获得的液位信息转换为钻井液池的排水装置控制器的控制信息。Wherein, the second liquid level sensor is connected to one end of the first resistor R1, one end of the first resistor R1 is connected to one end of the second resistor R2, the other end of the first resistor R1 and the other end of the second resistor R2 are both grounded, and the voltage The positive input end of the comparator is connected between one end of the first resistor R1 and one end of the second resistor R2, one end of the third resistor R3 is connected to one end of the fourth resistor R4, and the other end of the third resistor R3 is connected to the fourth resistor R3. The other ends of R4 are both grounded. The negative input end of the voltage comparator is connected between one end of the third resistor R3 and one end of the fourth resistor R4. The output end of the voltage comparator is connected to the positive input end of the amplifier. The negative input end of the amplifier terminal is grounded, and the output terminal of the amplifier is connected to the controller of the drainage device. Through the above method, the second liquid level sensor can be used to measure and obtain the liquid level information, and then the measured liquid level information can be converted into the data of the drainage device controller of the drilling fluid pool. control information.
其中，在一些实施例中，所述装置还包括获得单元，所述获得单元用于获得钻井液的PH值信息，所述判断单元还用于判断钻井液的PH值是否超过PH阈值，若超过则关闭第二液位测量单元开启第一液位测量单元。其中，在某些情况下，如地层里一般都会有氰化物硫化物产出，导致钻井液内混有碳酸硫酸根这些离子，酸化压裂的时候需要主动配入酸性的压裂液，这些都会导致钻井液的PH值出现酸性，在酸性条件下则不适合液位传感器的工作，会导致其腐蚀严重，因此，此刻则可以在即使不是泡沫钻井液的情况下也可以开启第一液位测量单元。Wherein, in some embodiments, the device further includes an obtaining unit, the obtaining unit is used to obtain the PH value information of the drilling fluid, and the judging unit is also used to judge whether the PH value of the drilling fluid exceeds the PH threshold. If it exceeds the PH value, Then the second liquid level measuring unit is turned off and the first liquid level measuring unit is turned on. Among them, in some cases, for example, cyanide sulfide is generally produced in the formation, causing the drilling fluid to be mixed with carbonic acid sulfate ions. During acidification fracturing, it is necessary to actively add acidic fracturing fluid, which will cause This causes the PH value of the drilling fluid to become acidic. Under acidic conditions, it is not suitable for the work of the liquid level sensor and will cause serious corrosion. Therefore, at this moment, the first liquid level measurement can be started even if the drilling fluid is not foam. unit.

申请人研究发现在进行液位测量时，由于泡沫钻井液在使用的过程中会产生较多的气泡，而大型的气泡则会浮在液面上，导致液面上有一层泡沫层，而利用摄像机或照相机在拍摄图像识别液位时则会错误的将泡沫层当成最上面的液位层进行识别，导致识别不准确，为了解决该问题，本发明设计了浮块，浮块可以漂浮在液面上，可以在随着液面的上升或下降在柱体上滑动，并且浮块具有一定的重量可以漂浮在液面上的同时可以压破泡沫，这样通过浮块就可以真实的反应出真实的液位，实现钻井液液位的准确测量。The applicant's research found that when measuring liquid level, foam drilling fluid will produce more bubbles during use, and large bubbles will float on the liquid surface, resulting in a layer of foam on the liquid surface. When a camera or camera takes an image to identify the liquid level, it will mistakenly identify the foam layer as the top liquid level layer, resulting in inaccurate identification.
