[0002] In recent years, with rising living standards and increased safety awareness, natural gas has gradually replaced coal gas in millions of households. This widespread adoption of natural gas has led to the construction of natural gas pipelines. Natural gas pipeline construction must consider the surrounding geological environment to ensure pipeline safety. The ability to visually display the structure and properties of geological layers is a crucial factor in natural gas pipeline excavation.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0021] Currently, geological layer data analysis and the generation of corresponding three-dimensional geological models are often performed on desktop clients. Drilling equipment uploads drilling data to the computer's desktop client. The algorithm deployed in the desktop client analyzes the drilling data, determines the geological layer data based on the drilling data analysis results, and constructs a three-dimensional geological model based on the data of the drilling sampling points. However, this solution must be performed on a designated desktop client. If the solution is implemented on other devices, the corresponding software or work terminal must be downloaded. This makes the solution incompatible with other systems and leads to low universality. In addition, constructing a three-dimensional geological model on the desktop client requires a large number of sampling points, which requires analyzing a large amount of sampling point data to accurately locate the position of each geological layer. The three-dimensional geological model is constructed based on the analysis results of the drilling data from a large number of sampling points. This makes the construction of the three-dimensional geological model complex and prevents the rapid generation of the three-dimensional geological model.

[0022] To this end, an embodiment of the present application provides a method for displaying geological bodies in layers, which obtains drilling data collected by drilling equipment, analyzes the drilling data to obtain basic stratigraphic information and sampling point information, and writes the information into a geological database. The drilling data is interpolated to obtain interpolation point data, and the conditions of each geological layer of the geological body are determined based on the interpolation point data. A three-dimensional geological body model is generated based on each geological layer data and basic stratigraphic information. This solution can fuzzily construct a three-dimensional geological body model based on the interpolation results of a small number of sampling points, and attach the geological conditions corresponding to each geological layer to the three-dimensional geological body model, which can achieve the effect of simplifying the construction of the three-dimensional geological body model and quickly outputting the three-dimensional geological body model.

Acquire drilling data of a geological body and write the drilling data into a geological database, wherein the drilling data includes basic stratigraphic information and sampling point information.

[0025] Optionally, drilling data of a geological body is collected by drilling equipment. A geological body refers to a crustal inclusion containing various geological layers. The drilling equipment enters the geological body through a drill bit to collect drilling data. The computer device obtains the drilling data collected by the drilling equipment via wireless communication technology. The computer device analyzes the drilling data to determine the basic stratigraphic information and sampling point information contained in the drilling data.

[0026] Optionally, basic stratigraphic information is used to indicate soil properties and soil types within the geological body. Sampling point information includes the current depth, longitude, and latitude of the sampling point, as well as the soil properties and type of the sampling point's location. Soil properties included in basic stratigraphic information may include sandy soil, clay soil, and loam; soil types may include red soil, brown soil, brown soil, black soil, chestnut soil, desert soil, fluvo-aquic soil (including sandy black soil), silt soil, paddy soil, wet soil (meadow, marsh soil), saline-alkali soil, lithologic soil, and alpine soil; this application does not impose specific limitations on this. It is worth noting that the current depth of the sampling point indicates the depth of the sampling point below the surface.

[0027] Figure 2 A schematic diagram of a single drilling data of a geological body provided in the embodiment of the present application, see Figure 2Each borehole data point on a geological body includes basic stratigraphic information and sampling point information. Each borehole data point can contain multiple sampling points, and the sampling point values are random. The number of sampling points in each borehole data point is not fixed and unique. For example, if the basic stratigraphic information includes: water surface, fine sand, cobblestone, and weathered sandstone, there are four sampling points. This application does not impose specific restrictions on this.

[0028] It is worth noting that the information of each sampling point serves as the reference information of the soil properties of the stratum. For example, if the soil property of a sampling point a on a certain borehole data A is yellow sand, then the soil property of the reference stratum is yellow sand.

[0029] Optionally, detailed stratigraphic information can be obtained based on the basic stratigraphic information and sampling point information contained in the drilling data. The detailed stratigraphic information includes: stratigraphic age, stratigraphic name, stratigraphic thickness, rock name, lithology description and bottom boundary depth, etc. This application does not make specific limitations on this.

[0030] Optionally, basic stratigraphic information and sampling point information contained in the drilling data are written into the geological database, and detailed stratigraphic information obtained from the drilling data analysis is also written into the geological database.

[0031] As a possible implementation method, the user can also directly enter the geological location attributes, material attributes of each stratum, thickness of each stratum and other attribute information of the geological body on the computer device based on the drilling data of the drilling equipment.

This interpolation process can determine whether each borehole data meets the requirements for 3D geological modeling and whether the borehole data can accurately display the geological attribute characteristics of the geological body. The target borehole data can then be associated with the interpolation point data to enhance the coherence of the borehole data and thus ensure the construction of the 3D geological model.

[0035] Optionally, interpolation processing can be performed on the borehole data in the geological body to determine the geological information of the relevant unknown points and the geological information of all points in the relevant area based on the information of each known sampling point. It is worth noting that the borehole data has the characteristics of distribution coefficient and high discreteness.

[0036] Optionally, the borehole data can be interpolated using a spatial interpolation algorithm to obtain the interpolation result. The spatial interpolation algorithms applicable to borehole data include: inverse distance weighting method, bilinear polynomial interpolation method, spline curve interpolation method and Kriging interpolation algorithm. Among them, the inverse distance weighting method is applicable to scenarios where known points are evenly distributed and have high regularity, the neighboring point interpolation algorithm is applicable to scenarios where known points are evenly distributed and have low accuracy requirements, and the spline curve interpolation method is applicable to scenarios where known points are numerous and dense. This application takes the Kriging interpolation algorithm as an example, but it does not mean that only the Kriging interpolation algorithm can be applied. The best interpolation algorithm is selected according to the specific environment, and this application does not make specific restrictions on this.

[0037] Optionally, the interpolation point data is used to indicate data of a point to be interpolated, and the interpolation point data includes information such as longitude, latitude, stratum thickness, and soil properties of the point to be interpolated.

[0039] Optionally, data of each geological layer of the geological body can be determined based on the interpolation point data, and interpolation processing is performed on known sampling points in each geological layer to determine the interpolation point data in each geological layer.

[0040] Optionally, the longitude, latitude, stratum thickness, starting line elevation, end line elevation and other data of the geological layer where the interpolation point is located can be determined based on the interpolation point data.

[0041] S104: Establish a three-dimensional geological body model of the geological body based on the geological layer data and basic stratigraphic information.

[0042] Optionally, a three-dimensional geological body model of each geological layer can be determined based on the geological layer data.

[0043] S105. Output and display the three-dimensional geological body model.

[0044] Optionally, the three-dimensional geological body model, as well as the geological layer names and soil properties of each geological layer on the three-dimensional geological body, are displayed via a visualization interface on a computer device.

[0045] In an embodiment of the present application, borehole data of a geological body is collected by drilling equipment or other geophysical exploration methods, the borehole data is analyzed to determine basic stratigraphic information and sampling point information of the geological body, each borehole data is interpolated to determine whether each borehole data meets the requirements for constructing a three-dimensional geological body model, and whether each borehole data can accurately display the geological attribute characteristics of the geological body, the sampling points contained in each target borehole data are associated via interpolation points, the geological layer data of the geological body are determined based on the interpolation point data, and a three-dimensional geological body model is established based on the geological layer data and basic stratigraphic information, the three-dimensional geological body model is displayed through a visual interface, and the stratigraphic name and soil properties corresponding to each geological layer are attached to each geological layer on the three-dimensional geological body model. Among them, the borehole data are sparsely distributed and irregular, and the interpolation processing is used to associate the borehole data that can represent the geological attribute characteristics of the geological body and determine the information of unknown sampling points around each sampling point, so as to achieve the purpose of establishing a three-dimensional geological body model based on the coefficient borehole data, and to achieve the effect of simplifying the construction of the three-dimensional geological body model. In addition, establishing a three-dimensional geological body model based on sparse drilling data can improve the efficiency of establishing the three-dimensional geological body model and achieve the effect of quickly outputting the three-dimensional geological body model.

[0046] In one possible implementation, see Figure 3 The operation of step S102 may specifically be: S301. Determine the cross-section information corresponding to each geological layer based on basic stratum information and sampling point information.

[0047] Optionally, the cross-section information corresponding to each geological layer can be determined based on the basic stratigraphic information and sampling point information. The cross-section information is used to indicate the stratification of the geological body and the geological properties of each geological layer. The cross-section information includes the known sampling point information of each geological layer, the name of the geological layer, the age of the geological layer, the thickness of the geological layer, the soil properties of the geological layer, etc. The name of the geological layer can be a pebble layer, loess layer, clay layer, sandstone layer, etc., and the age of the geological layer can be a fossil layer, biological layer, etc. This application does not make specific limitations on this.

[0048] S302: Perform interpolation calculation based on the cross-section information corresponding to each geological layer to obtain the regional range information of each geological layer and the elevation information of the interpolation point.

[0049] Optionally, interpolation calculation is performed based on the known sampling point information contained in the cross-section information corresponding to each geological layer to determine the interpolation point data corresponding to the target sampling point, and to determine the regional range information of each geological layer and the elevation information of the interpolation point.

[0050] Optionally, the regional range information of each geological layer includes coordinate information, elevation information, geological layer name, and range of each sampling point within the geological layer. The range of the geological layer is determined by the coordinates of the farthest sampling point within the geological layer and the coordinates of the interpolation point. The elevation information of the geological layer is used to indicate the underground depth.

[0051] Optionally, the elevation information of the interpolation point includes elevation information in the geological volume where the interpolation point is located, point information of the interpolation point, etc. The elevation information of the interpolation point may indicate the thickness of the geological layer where the interpolation point is located.

[0052] In the embodiments of the present application, cross-sectional information of each geological layer of the geological body can be determined by analyzing basic stratigraphic information of the geological body and sampling point data. The cross-sectional information of the geological layer can reflect the geological stratification and geological properties of each geological layer. Interpolation calculations are performed on the cross-sectional information corresponding to each geological layer to determine the regional range information of each geological layer and the elevation information of each interpolation point. This establishes the basis for a three-dimensional geological layer model in the three-dimensional geological body model. In this way, the effect of quickly outputting a three-dimensional geological body model can be achieved.

[0053] In one possible implementation, see Figure 4 The operation of step S302 may specifically be: S401 , performing interpolation calculation according to the number of sampling points included in the cross-section information corresponding to each geological layer, the coordinates of each sampling point, and the preset weight coefficients of each sampling point to determine the coordinates of at least one interpolation point in each geological layer.

[0054] Optionally, interpolation calculation is performed on the number of sampling points, the coordinates of each sampling point and the preset weight coefficients of each sampling point contained in the cross-section information corresponding to each geological layer, so as to determine the coordinates of at least one interpolation point in each geological layer, and strongly associate each sampling point through the interpolation point coordinates.

[0055] Optionally, the number of sampling points contained in the cross-section information corresponding to each geological layer is determined by the number of sampling points in the geological layer in the drilling data. The number of sampling points corresponding to each geological layer is random. The sampling points serve as reference points for the geological attribute characteristics of each geological layer. The number of sampling points contained in each geological layer is at least one. This application does not make any specific restrictions on this.

[0056] Optionally, the coordinates of the sampling points associated with the points to be interpolated in each geological layer and the weight coefficients of the associated sampling points are calculated and the weighted average is obtained to determine the coordinates of at least one interpolation point. The number of interpolation points in each geological layer is inconsistent, which is mainly used to strongly associate discrete value points. The similarity of each sampling point associated with the point to be interpolated is relatively high.

[0057] S402: Connect the coordinates of each interpolation point in the geological layer to obtain three-dimensional grid data of the geological layer, and obtain regional range information of the geological layer based on the three-dimensional grid data and the geological layer identifier input by the user.

[0058] Optionally, the coordinates of each interpolation point in the geological layer are connected to form multiple non-overlapping triangles, and a three-dimensional grid of the irregular geological layer is generated through the GIS system. The data corresponding to the interpolation point is inserted into the corresponding position of the three-dimensional grid to obtain the three-dimensional grid data of the geological layer. Based on the three-dimensional grid data and the identification of the geological layer input by the user, the interpolation point coordinates, elevation information, geological layer name, etc. in the regional range information of each geological layer can be determined.

[0059] S403: Determine the elevation information of the interpolation point in the geological layer according to the elevation information of the associated sampling point of the interpolation point, and the distance between the associated sampling point and the interpolation point is less than a preset threshold.

[0060] Optionally, the elevation information of the geological layer interpolation point can be determined based on the elevation information of the sampling points associated with the interpolation point. The sampling points associated with the interpolation point have a high similarity, and the elevation information of the interpolation point can be determined by averaging the elevation information of each sampling point.

[0061] Optionally, the distance between each sampling point associated with the interpolation point and the interpolation point is less than a preset threshold, thereby ensuring that the address attributes of each associated sampling point are consistent and that the similarity of the associated sampling points is maintained. The preset threshold is a manually set distance threshold, which may be 4 cm, 3 cm, or the like, and is not specifically limited in this application.

[0062] In an embodiment of the present application, interpolation processing is performed based on the number of sampling points, coordinates of each sampling point, and weight information of each sampling point included in the cross-sectional information of each geological layer. The coordinates of the interpolation points in each geological layer are determined, and the interpolation coordinates of each geological layer are connected to obtain multiple non-overlapping triangles. These non-overlapping triangles are converted into an irregular three-dimensional grid using a GIS system. The geological attributes and coordinates contained in each interpolation point are added to the three-dimensional grid to obtain three-dimensional grid data. Based on the three-dimensional grid data and the geological layer identifier input by the user, the regional range information of each geological layer is determined. The elevation information of each interpolation point is determined by taking a weighted average of the elevation information of the associated sampling points of the interpolation point, wherein the distance threshold between each associated sampling point and the interpolation point is less than a preset threshold, thereby achieving rapid modeling. In this way, the effect of quickly outputting a three-dimensional geological model can be achieved.

[0063] In one possible implementation, see Figure 5 The operation of step S401 may specifically be: S501: Determine the geographical weighted coordinates of each sampling point according to the coordinates corresponding to each sampling point and the weight coefficient of each sampling point.

[0064] Optionally, the coordinates corresponding to each sampling point are also called the geographic coordinates of each sampling point. The coordinates of each sampling point are used to indicate the longitude, latitude and underground depth of each sampling point. The weight coefficient of each sampling point is determined by the geological attributes represented by each sampling point. The more geological attribute characteristics contained in the sampling point information, the greater the weight coefficient corresponding to the corresponding sampling point.

[0065] Optionally, the weight coefficient corresponding to each sampling point is obtained by training a learning network model and is used to indicate the importance of the sampling point. Based on the coordinates of each sampling point and the weight coefficient of each sampling point, the geographical weighted coordinates of the sampling point can be determined. The weighted geographical coordinates of the sampling point can be obtained by multiplying the geographical coordinates of each sampling point by the weight coefficient.

[0066] S502: Determine the coordinates of each interpolation point according to the number of sampling points and the geographical weighted coordinates of each sampling point.

[0067] Optionally, the coordinates of the points to be interpolated may be determined according to the geographic weighted coordinates of the associated sampling points corresponding to the points to be interpolated in each geological layer and the number of associated sampling points. The coordinates of the interpolation points are geographic coordinates in geodetic coordinates.

[0068] Optionally, the associated sampling points have a high similarity, and determining the interpolation points based on the associated sampling points can enhance the coherence between the sampling points and ensure the accuracy of establishing the three-dimensional geological layer model.

[0069] Optionally, the coordinates of the interpolation point are determined according to a weighted average of the geographical weighted coordinates of the associated sampling points.

[0070] In an embodiment of the present application, the geographic weighted coordinates corresponding to each sampling point contained in the geological layer and the weight coefficient corresponding to each sampling point are used to determine the geographic coordinates corresponding to each sampling point. According to the number of associated sampling points corresponding to the point to be interpolated in the geological layer and the geographic weighted coordinates of the associated sampling points, the geographic coordinates of the interpolation point can be determined. In this way, the geological data of the three-dimensional geological body model can be determined, thereby achieving the effect of simplifying the construction of the three-dimensional geological body model.

[0071] In one possible implementation, see Figure 6 The operation of step S502 may specifically be: S601: Convert the geographical weighted coordinates of each sampling point to obtain the spatial weighted coordinates of each sampling point.

[0072] Optionally, a coordinate conversion algorithm is used to convert the geographic weight coordinates of each sampling point into the spatial weight coordinates corresponding to each sampling point. The spatial weight coordinates are used to indicate the position information of each sampling point in a three-dimensional coordinate system. The three-dimensional coordinate system is a standard coordinate system for establishing a three-dimensional geological body model.

[0073] It is worth noting that the geographic weight coordinates of each sampling point are converted into corresponding spatial weight coordinates, so that the coordinates of each sampling point are mapped from the geodetic coordinate system to the three-dimensional coordinate system. The conversion of geographic weight coordinates into spatial weight coordinates can be implemented by relying on code written in Python or other conversion functions. This application does not make specific restrictions on this.

[0074] S602: Determine the coordinates of each interpolation point according to the number of sampling points and the spatial weight coordinates of each sampling point.

[0075] Optionally, the coordinates of each interpolation point can be determined according to the number of sampling points and the spatial weight coordinates of each sampling point, wherein the number of sampling points refers to the number of sampling points associated with the point to be interpolated, and the point to be interpolated and its associated sampling points are in the same geological layer.

[0076] Optionally, the coordinates corresponding to the point to be interpolated may be determined according to the spatial weight coordinates of the sampling points associated with the point to be interpolated in the geological layer and the number of associated sampling points. The coordinates of the interpolation point are three-dimensional spatial coordinates.

[0077] In an embodiment of the present application, the geographic weight coordinates of each sampling point contained in the geological layer are converted into the spatial weight coordinates corresponding to the sampling points through a conversion algorithm, the coordinates of each interpolation point are determined according to the spatial weight coordinates of each associated sampling point for establishing the interpolation point and the number of associated sampling points, the geological data of the geological layer is determined according to the interpolation result corresponding to the drilling data, three-dimensional grid data is established according to the spatial weight coordinates corresponding to each sampling point, the spatial coordinates of each interpolation point and the standard three-dimensional coordinate system, and a geological layer model of each geological layer is established according to the three-dimensional grid data, basic stratigraphic information and the thickness of each geological layer. In this way, the construction of the three-dimensional geological body model can be simplified and the three-dimensional geological body model can be quickly output.

[0078] In one possible implementation, see Figure 7 The operation of step S103 may specifically be: S701. Determine the identification of the geological layer according to the regional range information of the geological layer.

[0079] Optionally, the regional range information of the geological layer includes the coordinate information of each sampling point within a geological layer, the coordinate information of each point to be interpolated, the name of the geological layer, and the soil properties of the geological layer. The identification of the geological layer can be determined based on the regional range information of the geological layer. The identification of the geological layer includes the name of the geological layer and the soil properties of the geological layer.

Figure 10 Based on wireless communication technology, borehole data collected by a drilling device is obtained through a data interface on a computer device, and the borehole data is analyzed to determine basic stratigraphic information of the target geological body and information of each sampling point. Detailed stratigraphic information is determined based on the basic stratigraphic information of the borehole data and information of each sampling point. The basic stratigraphic information, information of each sampling point, and detailed stratigraphic information are written into a geological database. A Kriging interpolation algorithm is used to determine whether the information of each sampling point meets the requirements of three-dimensional geological body modeling and whether the borehole data corresponding to each sampling point can represent the geological properties of the geological body. Interpolation points and interpolation results are determined based on target sampling points in the geological layer and associated sampling point information and the number of associated sampling points.

A three-dimensional geological body model is generated using the three-dimensional model. The three-dimensional geological body model and each geological layer model are displayed on a computer visualization web page, and corresponding geological identifiers, geological thickness, soil properties, and other information are attached to each geological layer. In this way, the display results can be made more intuitive and clear, allowing users to quickly understand the geological properties of the current geological body.

The geological layer identifiers corresponding to each geological layer are added to each geological layer to indicate the geological properties of each geological layer. The geological layer effect of the three-dimensional geological body model is displayed on a visualization page. Among them, each geological layer model is displayed in the established three-dimensional geological body model, and each geological layer model is assigned its corresponding geological layer identifier, making the three-dimensional geological body model more readable. In this way, the effect of quickly outputting the three-dimensional geological body model can be achieved.
