目前常用的确定勘探区的砂岩型铀矿矿化部位的方法分为用于室内环境和野外环境两类。常用于室内环境的方法为获取勘探区的砂岩型铀矿样品，并对获取的样品中的铀含量进行分析，进而确定勘探区的砂岩型铀矿矿化部位。常用于野外环境的方法为通过测井获得勘探区的测井曲线、井内示踪剂的伽玛数值等参数，并对这些参数进行分析，进而确定勘探区的砂岩型铀矿矿化部位。但在野外环境中进行测井时，测井操作容易受到环境的影响，并且测井过程耗时较长，操作较为繁琐。At present, the commonly used methods for determining the mineralized locations of sandstone-type uranium deposits in exploration areas are divided into two categories: indoor environments and field environments. The method commonly used in indoor environments is to obtain sandstone-type uranium samples in the exploration area, and analyze the uranium content in the obtained samples to determine the mineralized locations of sandstone-type uranium deposits in the exploration area. The method commonly used in field environments is to obtain the logging curves of the exploration area, the gamma values of the tracers in the wells and other parameters through well logging, and analyze these parameters to determine the mineralized locations of sandstone-type uranium deposits in the exploration area. However, when logging in a field environment, the logging operation is easily affected by the environment, and the logging process is time-consuming and cumbersome to operate.
针对上述技术问题，本申请的实施例提供一种通过矿物组合确定勘测区的砂岩型铀矿矿化部位的方法。In view of the above technical problems, an embodiment of the present application provides a method for determining the mineralized location of sandstone-type uranium deposits in a survey area through mineral combinations.
如图1所示，其示出本申请的实施例提供的通过分析勘测区的黏土矿物组合来确定勘测区的砂岩型铀矿矿化部位的流程图。其可以包括以下步骤：S1：采集勘测区的不同深度位置的砂岩型铀矿石样品；S2：对砂岩型铀矿石样品进行分析，获得不同深度的样品中的矿物组成成分以及不同深度的矿物组成成分的含量；S3：确定随着深度的变化而含量具有突变的矿物组成成分；S4：对S3步骤中确定的矿物组成成分在不同的深度范围的含量进行分析，确定S3步骤中确定的矿物组成成分不同的含量对应的不同深度范围；S5：根据S4步骤确定的深度范围，确定勘测区的砂岩型铀矿矿化部位。As shown in Figure 1, it shows a flow chart of determining the sandstone-type uranium mineralization site in the survey area by analyzing the clay mineral combination in the survey area provided by the embodiment of the present application. It may include the following steps: S1: Collecting sandstone-type uranium ore samples at different depths in the survey area; S2: Analyzing the sandstone-type uranium ore samples to obtain the mineral components in the samples at different depths and the contents of the mineral components at different depths; S3: Determining the mineral components whose contents have a sudden change with the change of depth; S4: Analyzing the contents of the mineral components determined in step S3 in different depth ranges to determine the different depth ranges corresponding to the different contents of the mineral components determined in step S3; S5: Determining the sandstone-type uranium mineralization site in the survey area according to the depth range determined in step S4.
本申请的实施例提供的方法通过确定随着深度的变化出现含量突变的矿物组成成分，并根据这些矿物组成成分不同的含量对应的不同深度范围来确定勘探区的砂岩型铀矿矿化部位，从而，可以实现在野外没有测井曲线以及伽马数值的条件下确定砂岩型铀矿矿化部位。The method provided in the embodiments of the present application determines the mineral components whose content changes suddenly with the change of depth, and determines the mineralized location of sandstone-type uranium ore in the exploration area according to the different depth ranges corresponding to the different contents of these mineral components. Therefore, it is possible to determine the mineralized location of sandstone-type uranium ore in the field without well logging curves and gamma values.
本申请的实施例提供的方法既可以用于室内环境，又可以用于野外环境。由于本发明的发明是通过组成成分不同的含量对应的不同深度范围来确定的勘探区的砂岩型铀矿矿化部位，从而无需进行测井，其也可以用于无法获得测井曲线或没有携带测量仪器的情况。The method provided in the embodiment of the present application can be used in both indoor and outdoor environments. Since the invention of the present invention determines the sandstone-type uranium mineralization site in the exploration area by different depth ranges corresponding to different contents of components, there is no need to perform well logging, and it can also be used in situations where well logging curves cannot be obtained or measuring instruments are not carried.
在一些实施例中，在S1步骤中，可以通过钻井取心获得不同深度位置的砂岩型铀矿石的岩心作为砂岩型铀矿石样品。In some embodiments, in step S1, cores of sandstone-type uranium ore at different depths may be obtained by coring in a well as sandstone-type uranium ore samples.
在一些实施例中，在S1步骤中，在获得砂岩型铀矿石样品后，可以对砂岩型铀矿石样品进行预处理，以便于在S2步骤中对砂岩型铀矿石样品进行分析。In some embodiments, in step S1, after obtaining the sandstone-type uranium ore sample, the sandstone-type uranium ore sample may be pre-processed to facilitate analysis of the sandstone-type uranium ore sample in step S2.
在一些实施例中，对对砂岩型铀矿石样品的预处理可以包括以下内容：对样品进行清洗，去除样片表面的泥浆；对清洗完成后的样品进行烘干；将清洗烘干完成后的样品进行破碎；将破碎后的样品采用刮片的方法制成分析片。In some embodiments, the pretreatment of sandstone-type uranium ore samples may include the following: cleaning the samples to remove mud on the surface of the samples; drying the cleaned samples; crushing the cleaned and dried samples; and making analysis slices from the crushed samples using a scraping method.
在一些实施例中，可以将清洗后的样品放在鼓风干燥箱内，在80℃下烘干24h，得到烘干后的样品。In some embodiments, the cleaned sample can be placed in a forced air drying oven and dried at 80° C. for 24 hours to obtain a dried sample.
在一些实施例中，在破碎样品时，可以将样品破碎成60-80目的样品，例如可以破碎成70目的样品。便于后期利用X衍射仪测定黏土矿物成分及含量。In some embodiments, when crushing the sample, the sample can be crushed into 60-80 mesh samples, for example, into 70 mesh samples, so as to facilitate the determination of clay mineral composition and content by X-ray diffractometer in the later stage.
在一些实施例中，在S1步骤中，在采样时，针对不同的砂体采样的间距可以不同。In some embodiments, in step S1, during sampling, the intervals for sampling different sand bodies may be different.
在一些实施例中，在S1步骤中，灰色砂体的采样的间距可以比其他砂体的采样间距小。利于后期圈定的矿化部位更加精确。In some embodiments, in step S1, the sampling interval of the gray sand body may be smaller than the sampling interval of other sand bodies, so as to make the mineralized part delineated later more accurate.
在一些实施例中，在灰色砂体中的采样间距可以为20cm~30cm，在其他砂体中的采样间距可以为50cm~100cm。In some embodiments, the sampling interval in the gray sand body may be 20 cm to 30 cm, and the sampling interval in other sand bodies may be 50 cm to 100 cm.
例如，在其他砂体中的采样间距为80cm，在灰色砂体中的采样间距为25cm。For example, the sampling interval in other sand bodies is 80 cm, and the sampling interval in gray sand bodies is 25 cm.
在一些实施例中，在S2步骤中获得的矿物组成成分为黏土矿物组成成分。在一些实施例中，在S2步骤中，确定的矿物组成成分为蒙脱石、绿泥石、高岭石和伊利石。In some embodiments, the mineral components obtained in step S2 are clay mineral components. In some embodiments, in step S2, the mineral components determined are montmorillonite, chlorite, kaolinite and illite.
在一些实施例中，在S2步骤中，可以利用X射线荧光光谱仪或高光谱扫描仪分析样品中黏土矿物组成成分及含量。In some embodiments, in step S2, an X-ray fluorescence spectrometer or a hyperspectral scanner may be used to analyze the composition and content of clay minerals in the sample.
在一些实施例中，在室内环境中可以利用X射线荧光光谱仪分析样品中黏土矿物组成成分及含量，在野外环境中可以利用高光谱扫描仪分析样品中黏土矿物组成成分及含量。In some embodiments, an X-ray fluorescence spectrometer may be used to analyze the composition and content of clay minerals in a sample in an indoor environment, and a hyperspectral scanner may be used to analyze the composition and content of clay minerals in a sample in a field environment.
在一些实施例中，在S3步骤中，可以绘制不同的矿物组成成分含量随着深度的变化折线图，并可以利用折线图来确定随着深度的变化而含量具有突变的矿物组成成分。In some embodiments, in step S3, a line graph showing the changes in the contents of different mineral components with depth may be plotted, and the line graph may be used to determine the mineral components whose contents have a sudden change with depth.
在一些实施例中，可以根据每一种矿物组成成分的含量随着深度的变化的折线图，并可以根据每一种矿物的折线图中是否存在突变点来判断该矿物组成成分是否会随着深度的变化而出现突变。其中，突变点是指折线图的走向发生变化的点。In some embodiments, a line graph showing the content of each mineral component changing with depth can be used to determine whether the mineral component will mutate with depth, and whether there is a mutation point in the line graph of each mineral. The mutation point refers to a point where the direction of the line graph changes.
例如，在折线图上存在一个点P，在P点之前的折线图的走向为逐渐上升，在P点之后的折线图的走向为逐渐下降，此时，点P就是折线图上的一个突变点。For example, there is a point P on a line graph. The trend of the line graph before point P is gradually rising, and the trend of the line graph after point P is gradually falling. At this time, point P is a mutation point on the line graph.
在一些实施例中，在S3步骤中确定的含量随深度变化而出现突变的矿物成分为蒙脱石、绿泥石、高岭石。In some embodiments, the mineral components whose contents vary drastically with depth as determined in step S3 are montmorillonite, chlorite, and kaolinite.
在一些实施例中，在S4步骤中，可以对出现突变点的矿物组成成分的折线图进行拟合，得到矿物组成成分含量变化的曲线图。In some embodiments, in step S4, a line graph of the mineral components where the mutation point appears may be fitted to obtain a curve graph of the change in the content of the mineral components.
在一些实施例中，在S4步骤中，可以根据S3步骤中绘制的折线图，利用矿物组成成分含量，确定该含量的对应的采集该样品的深度。In some embodiments, in step S4, the depth at which the sample was collected corresponding to the content can be determined using the content of the mineral components according to the line graph drawn in step S3.
在一些实施例中，在S4步骤中，可以根据矿物组成成分含量变化的折线图，确定每种矿物组成成分含量变化的折线图的最高点或最低点对应的含量以及深度。In some embodiments, in step S4, the content and depth corresponding to the highest point or the lowest point of the line graph of the content change of each mineral component can be determined based on the line graph of the content change of the mineral component.
例如，蒙脱石的含量变化的折线图存在最低点，那么要确定蒙脱石的含量变化的折线图的最低点对应的含量和深度；绿泥石和高岭石的含量变化的折线图存在最高点，那么要分别确定绿泥石和高岭石的含量变化的曲线图的最高点对应的含量和深度。For example, if there is a lowest point in the line graph of montmorillonite content change, then it is necessary to determine the content and depth corresponding to the lowest point of the line graph of montmorillonite content change; if there is a highest point in the line graph of chlorite and kaolinite content change, then it is necessary to determine the content and depth corresponding to the highest point of the curve graph of chlorite and kaolinite content change respectively.
在一些实施例中，S4步骤中还可以包括确定矿物组成成分中的每个成分的预定含量对应的深度上限和深度下限。In some embodiments, step S4 may further include determining an upper depth limit and a lower depth limit corresponding to a predetermined content of each component in the mineral composition.
在一些实施例中，在S4步骤中，可以根据以下内容确定矿物组成成分中的每个成分的预定含量：当矿物组成成分含量变化的折线图存在最高点时，则预定含量为最高点对应的含量的三分之二；当矿物组成成分含量变化的折线图存在最低点时，则预定含量为最低点对应的含量的二分之三。In some embodiments, in step S4, the predetermined content of each component in the mineral component can be determined according to the following content: when there is a highest point in the line graph of the change in the content of the mineral component, the predetermined content is two-thirds of the content corresponding to the highest point; when there is a lowest point in the line graph of the change in the content of the mineral component, the predetermined content is two-thirds of the content corresponding to the lowest point.
例如，在一些实施例中，可以按照以下S41-S43步骤选择矿物组成成分的深度上限和深度下限。For example, in some embodiments, the upper and lower depth limits of the mineral composition may be selected according to the following steps S41-S43.
S41：确定蒙脱石含量最低值，确定蒙脱石含量最低值的3/2处的深度上限H1以及深度下限H2。S41: Determine the minimum value of the montmorillonite content, and determine the upper limit H1 and the lower limit H2 of the depth at 3/2 of the minimum value of the montmorillonite content.
S42：确定绿泥石含量最高值，确定绿泥石含量最高值的2/3处的深度上限H3以及深度下限H4。S42: Determine the maximum value of chlorite content, and determine the upper limit H3 and lower limit H4 of the depth at 2/3 of the maximum value of chlorite content.
S43：确定高岭石含量最高值，确定高岭石含量最高值的2/3处的深度上限H5以及深度下限H6。S43: Determine the maximum value of kaolinite content, and determine the upper limit H5 and lower limit H6 of the depth at 2/3 of the maximum value of kaolinite content.
在一些实施例中，在S5步骤中，可以根据深度上限和深度下限，确定勘测区的砂岩型铀矿矿化部位。更具体地，可以根据S4步骤确定的深度上限的最大值以及深度下限的最小值，确定勘测区的砂岩型铀矿矿化部位。In some embodiments, in step S5, the sandstone-type uranium mineralization site in the survey area can be determined according to the upper depth limit and the lower depth limit. More specifically, the sandstone-type uranium mineralization site in the survey area can be determined according to the maximum value of the upper depth limit and the minimum value of the lower depth limit determined in step S4.
在一些实施例中，确定勘测区的砂岩型铀矿矿化部位的过程可以包括：确定S41、S42以及S43步骤中的深度上限中的最大值，确定S41、S42以及S43步骤中的深度下限中的最小值，根据上面提到的最小值以及最大值确定勘测区的砂岩型铀矿矿化部位。In some embodiments, the process of determining the sandstone-type uranium mineralization site in the survey area may include: determining the maximum value of the depth upper limits in steps S41, S42, and S43, determining the minimum value of the depth lower limits in steps S41, S42, and S43, and determining the sandstone-type uranium mineralization site in the survey area based on the minimum and maximum values mentioned above.
例如，在S41-S43步骤中，确定三个深度上限H1、H3和H5，通过比较，可以得到深度上限的最大值Hmax；在S41-S43步骤中，还确定三个深度下限H2、H4和H6，通过比较，可以得到深度下限的最小值Hmin。Hmax~Hmin对应的深度范围，即为砂岩型铀矿矿化部位。利用该方法可以帮助技术人员在野外无法立即获取测井曲线的情况，第一时间圈定矿化部位，准确且易操作。For example, in steps S41-S43, three upper depth limits H1 , H3 and H5 are determined, and by comparison, the maximum value Hmax of the upper depth limit can be obtained; in steps S41-S43, three lower depth limits H2 , H4 and H6 are also determined, and by comparison, the minimum value Hmin of the lower depth limit can be obtained. The depth range corresponding to Hmax ~ Hmin is the mineralized part of the sandstone-type uranium ore. The method can help technicians to identify the mineralized part in the first time when they cannot immediately obtain the logging curve in the field, which is accurate and easy to operate.
在鄂尔多斯盆地北部巴音青格利砂岩型铀矿床的直罗组作为勘测区的示例中，利用本申请的实施例提供的方法确定的砂岩型铀矿矿化部位为350m-358m，与实际情况较为符合。In the example of the Zhiluo Formation of the Bayingqinggeli sandstone-type uranium deposit in the northern Ordos Basin as the exploration area, the mineralized location of the sandstone-type uranium deposit determined by the method provided in the embodiment of the present application is 350m-358m, which is consistent with the actual situation.
对于本申请的实施例，还需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合以得到新的实施例。Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，本申请的保护范围应以权利要求的保护范围为准。The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
