[0029] In order to facilitate the understanding of the embodiments, first, the electronic device for executing the stratum line generation method disclosed by the embodiments of the present application will be introduced in detail.

[0030] As shown in Figure 1 , it is a block schematic diagram of an electronic device. The electronic device 100 can include a memory 111, a processor 113, an input output unit 115, and a display unit 117.

For example, the electronic device 100 can further include more or fewer components than those shown in the figure, or have a different configuration from that shown in the figure. Figure 1 Figure 1

[0031] The above-mentioned memory 111, processor 113, input and output unit 115, and display unit 117 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these elements can be electrically connected to each other through one or more communication buses or signal lines. The formation of the stratigraphic line includes one or more software modules stored in the memory 111 in the form of software or firmware (Firmware) or solidified in the operating system (Operating System, OS) of the electronic device 100, and the above-mentioned processor 113 is used to execute the executable modules stored in the memory. For example, the software function modules and computer programs included in the stratigraphic line generation device to realize the stratigraphic line generation method. The processor 110 can execute the computer program after receiving the execution instruction.

[0036] The electronic device 100 in the embodiment can be configured to execute each step in each method provided in the embodiments of the present application. The implementation process of the stratigraphic line generation method will be described in detail in the following several embodiments.

[0037] Please refer to Figure 2 , which is a flowchart of the stratigraphic line generation method provided in the embodiments of the present application. The specific process shown in FIG. 2 will be described in detail below. Figure 2

[0038] In step 201, point data of a target region is acquired.

[0039] Optionally, the target region is a region in which a stratigraphic line needs to be generated. The target region can include one or more point data.​

[0040] Optionally, the point data includes a depth of the borehole, the point data includes one or more stratum data of the borehole, the point data includes position data of the borehole, etc. The point data includes a plurality of stratum data.

[0041] In step 202, abnormal stratum data in the plurality of stratum data is removed to obtain to-be-processed stratum data.

[0042] Optionally, removing the abnormal stratum data in the plurality of stratum data can include: when two strata of a point position exist in a cross, the strata of the point position are processed according to actual distribution of strata of surrounding point positions.

[0043] For example, when stratum A and stratum B of point position p1 exist in a cross, that is, the stratum distribution of point position p1 is ABA. At this time, the stratum distribution of the surrounding of point position p1 needs to be determined. If the surrounding strata of point position p1 are all stratum A at this time, stratum B is not considered, and stratum B is regarded as a lens.

[0044] Optionally, removing the abnormal stratum data in the plurality of stratum data can include: when the upper and lower relationships of two strata at different point positions are inconsistent, part of the strata are processed according to overall stratum ordering distribution.

[0045] For example, when stratum A and stratum B at different point positions in a target region exist in inconsistent upper and lower relationships, according to overall stratum ordering distribution, a case in which overall stratum ordering distribution occurs less is not considered. For example, if the overall stratum ordering is that stratum A is on top, and a small part of stratum A is on the bottom, the small part of stratum A is not considered, and the small part of stratum A in the different point positions is regarded as a lens.

[0046] Optionally, removing the abnormal stratum data in the plurality of stratum data can include: when there is a point position with inconsistent sampling depth, shallow point position stratum data is virtually filled according to stratum data of surrounding point positions.

[0047] For example, when there are point positions with deeper sampling and point positions with shallower sampling, stratum data of the point positions with shallower sampling is virtually filled with reference to stratum data of surrounding deep point positions.

[0048] In step 203, to-be-processed stratum data is preprocessed to obtain creation information.

[0049] Optionally, preprocessing the to-be-processed stratum data can include: according to positions of each stratum in each point position, actual position information of each stratum of each point position is obtained, and the actual position information is processed according to a preset rule, so that the creation information is obtained.

[0050] In step 204, a stratum line of the target stratum is generated according to the creation information.

[0051] The target stratum is one or more strata of the target area. Accordingly, the stratum line can include one or more stratum lines.

[0052] Optionally, the creation information can include point group networking, and the creation data can include stratum ordering information.

[0053] In one possible implementation, in step 204, the stratum surface is processed according to the point group networking to obtain a smooth stratum surface, and the stratum line of the target stratum is generated according to the smooth stratum surface.

[0054] Optionally, the point group networking is a collection of multiple polygonal networks formed by multiple points. The point group networking information includes polygon information and polygonal network information. The point group networking can be determined according to the points.

[0055] Specifically, multiple points are connected by multiple line segments to form a polygon, multiple polygons are spliced to form a polygonal network, and the polygonal network is processed to obtain the point group networking.

[0056] Optionally, the polygonal network is processed before the multiple polygons are spliced.

[0057] For example, if a part of the polygon is outside the target area, the polygon is ignored. If the value of the bottom edge of the polygon is less than a first specified value, the polygon is ignored. For example, the first specified value can be 0.1, 0.3, 0.5, 1, etc.

[0058] The stratum line of the target stratum is generated according to the smooth stratum surface, including processing the smooth stratum surface to generate the stratum line of the target stratum.

[0059] In one possible implementation, the stratum line of the target stratum is generated according to the stratum surface, including: correcting the stratum surface according to stratum ordering information to obtain a corrected stratum surface; and cutting the corrected stratum surface to obtain the stratum line of the target stratum.

[0060] Optionally, the stratum ordering information can be generated according to a specific rule, and the stratum ordering information can be obtained directly through point data.

[0061] Optionally, the stratum surface is corrected through the stratum ordering information, including: determining an out-of-bound stratum surface through the stratum ordering information, and correcting the out-of-bound stratum surface.

[0062] For example, stratum A has a specific one area bottom surface A1, stratum B has a specific another area bottom surface B1, according to the stratum ordering information, it can be determined that the ordering of the stratum is stratum A, stratum B and stratum C from top to bottom, and the bottom surface B1 cannot cross the bottom surface A1. If the bottom surface B1 actually crosses the bottom surface A1 upward, it can be determined that the bottom surface B1 has crossed the boundary, and at this time, it needs to be corrected. The correction method can be: ignoring the area where the bottom surface B1 crosses the bottom surface A1, that is, coinciding the area where the bottom surface B1 crosses the bottom surface A1 with the bottom surface A1.

[0063] Optionally, the cutting of the corrected stratum surface can include vertical cutting of the stratum surface. After cutting, one or more stratum lines of the target stratum can be obtained.

[0064] In a possible implementation, before step 204, the stratum line generation method further includes: creating an initial point position polygon according to point position data; removing point position polygons in the initial point position polygon that do not meet a second set rule to obtain a to-be-processed point position polygon; and creating a point position network according to the to-be-processed point position polygon.

[0065] Optionally, the creating of the initial point position polygon according to the point position data can specifically be: connecting multiple point positions with straight lines to form a polygon according to an adjacency principle. The adjacency principle is that connecting the first point positions of adjacent point positions.

[0066] Optionally, the second set rule can be removing polygons outside a target area, and the second set rule can also be removing polygons with a value of a bottom edge vertical line / bottom edge less than a second specified value. The second specified value can be 0.1, 0.3, 0.5, 1, etc. The to-be-processed point position polygon is a point position polygon that meets the second set rule, and the to-be-processed point position polygon is spliced to form a point position network.

[0067] In a possible implementation, step 204 includes: determining, according to the stratum ordering information, that adjacent point positions exist in the same stratum; and connecting the same stratum with a straight line to generate a stratum line of the target stratum.

[0068] For example, if point position p3 and point position p4 are adjacent point positions, point position p3 includes stratum A, stratum B and stratum C, and point position p4 also includes stratum A, stratum B and stratum C. Connecting stratum A in point position p3 and stratum A in point position p4 forms a stratum line of stratum A. Connecting stratum B in point position p3 and stratum B in point position p4 forms a stratum line of stratum B. Connecting stratum C in point position p3 and stratum C in point position p4 forms a stratum line of stratum C.

[0069] For example, if the point p5 and the point p6 are adjacent points, the point p5 includes the stratum A, the stratum B and the stratum C, and the point p6 includes the stratum B, the stratum C and the stratum D. Connecting the stratum B in the point p5 and the stratum B in the point p6 forms the stratum line of the stratum B. Connecting the stratum C in the point p5 and the stratum C in the point p6 forms the stratum line of the stratum C.

[0070] In a possible implementation, the step 204 further includes: determining the unique stratum of the adjacent point according to the stratum ordering information; obtaining the pinch-out point of the unique stratum to the adjacent point; and generating the stratum line of the unique stratum according to the pinch-out point.

[0071] The unique stratum is the difference stratum between the adjacent points. For example, if the point p5 and the point p6 are adjacent points, the point p5 includes the stratum A, the stratum B and the stratum C, and the point p6 includes the stratum B, the stratum C and the stratum D, the unique stratum of the point p5 is the stratum A, and the unique stratum of the point p6 is the stratum D.

[0072] Optionally, when the current stratum appears as the unique stratum between two adjacent points, the point at which the current stratum becomes thin and disappears is the pinch-out point of the current stratum.

[0073] Optionally, the pinch-out point can be determined by the point group network information and the stratum information.

[0074] Optionally, the step of generating the stratum line of the unique stratum according to the pinch-out point includes: connecting the pinch-out point and a bottom point of the unique stratum to obtain the stratum line of the unique stratum.

[0075] Optionally, after obtaining the stratum line of the target stratum, the stratum line can be corrected. The correction of the stratum line can be performed by the upper pinch-out and the lower pinch-out.

[0076] For example, as shown in FIG. 4, the stratum line of the stratum A is corrected by the upper pinch-out and the lower pinch-out. Figure 3As shown, if the point p7 and the point p8 are two adjacent points, the point p7 has the strata A, B and D from top to bottom, the point p8 has the strata A, C and D from top to bottom, the strata from top to bottom are A, B, C and D according to the strata ordering information, and the current stratum type is B, then the point at which the stratum B gradually thins out until disappears between the point p7 and the point p8 is the pinch-out point of the stratum B. The solving method is as follows: the top point of the stratum B at the point p7 is d1, the bottom point of the stratum B at the point p7 is d2, and the top point of the stratum C at the point p8 is d3; the line connecting d1 and d3 is line1, the line connecting d2 and d3 is line2, line1 is the initial stratum line of the stratum A, and line2 is the initial stratum line of the stratum B; the intersection point d4 of the current stratum B partition line and the line connecting p7 and p8 is obtained on the plane, and a perpendicular line at d4 is line3; the intersection point of line1 and line3 is d5, and the intersection point of line2 and line3 is d6, that is, the pinch-out point can be d5 or d6; if the lower pinch-out is adopted, the pinch-out point is d5, line1 remains unchanged, and line2 is modified as the line connecting d2 and d5; if the upper pinch-out is adopted, the pinch-out point is d6, line2 remains unchanged, and line1 is modified as the line connecting d1 and d6. The current stratum B partition line is obtained according to the stratum partition, and the line connecting p7 and p8 is the line connecting the point p7 and the point p8.

[0077] In a possible implementation, step 203 comprises: sorting the to-be-processed stratum data by a first set rule to obtain the stratum ordering information.

[0078] The first set rule can be a geological sequence theory. The to-be-processed stratum data is sorted by the geological sequence theory to obtain the stratum ordering information.

[0079] The application obtains the point group network by obtaining and processing the point data, and obtains the stratum surface. After obtaining the stratum surface, the target stratum line is produced in multiple ways by combining the stratum ordering information. Not only the diversity and richness of the stratum line generation are realized, but also the automation of the stratum line generation is realized by setting the step to generate the bottom line, the work intensity of the staff is reduced, and the work efficiency is improved.
