[0048] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, the terms "first", "second", etc. are only used for distinction and cannot be understood as indicating or implying relative importance.

[0049] Please refer to Figure 1 , which is a flow diagram of a stratum analysis method provided by an embodiment of the present application. As shown in Figure 1 , the method includes steps S201-S204.

[0050] Step S201: Classify all drilling strata according to a preset index order to obtain occupancy ratio data of each type of stratum.

[0051] Drilling strata are the main survey means for obtaining geological information. Survey personnel drill holes at different positions in the target area to be surveyed, and obtain core samples from the drilling holes. From the core samples and drilling data, the names of the rock-soil, the lithological state, the color, the elevation, and the corresponding stratum thickness of the drilling strata can be obtained.

[0052] In this step, the preset order can be classified according to the primary and secondary order of the names of the rock-soil, the lithological state, the color, the elevation, and the thickness of the drilling strata. That is, when sorting and dividing the drilling strata, first compare and judge whether the names of the rock-soil drilled by two drilling holes are the same or similar, then compare the consistency of the lithological state, and then compare the color, the elevation, and the thickness. If the names of the rock-soil are the same or similar, they can be classified into the same type of stratum first. The method of classifying according to the preset index order can preliminarily classify the strata.

[0053] After the strata in the boreholes are classified according to the main and secondary orders of the rock name, lithological state, color, elevation and thickness, the proportion data of various strata need to be calculated, and the proportion data refers to the ratio of the number of boreholes of the same classified strata to the total number of boreholes.

[0054] For example, 10 boreholes are drilled in a certain area, and in the strata exposed in the 10 boreholes, there are 3 strata in the ZK1 borehole, which respectively contain different lithology; there are 5 strata in the ZK2 borehole, which respectively contain different lithology; and there are 4 strata in the ZK3 borehole, which respectively contain different lithology. Among them, the 2# layer of the ZK1 borehole and the 3# layer of the ZK2 borehole have the same rock name (for example, both are sandstone) and the same lithological state (dense), but the colors are different. By using the preliminary sorting classification method, the 2# layer of the ZK1 borehole and the 3# layer of the ZK2 borehole are classified as the same strata, and therefore the proportion data of the sandstone strata is the ratio of the number of boreholes of the same classified strata to the total number of boreholes, and the calculation result is: ((ZK1-2)+(ZK2-3)) / (ZK1+ZK2+ZK3+...+ZK10) x 100% = 20%. The proportion data of other lithological strata can also be calculated in turn according to the method.

[0055] Step S202: According to the proportion data, obtain a stratum elevation / proportion distribution characteristic map set.

[0056] Take the proportion data as the horizontal coordinate and the elevation as the vertical coordinate;

[0057] According to different deposition and diagenetic environments, a preset number of stratum elevation / proportion distribution characteristic map sets are obtained, wherein each stratum elevation / proportion distribution characteristic map represents a deposition and diagenetic environment characteristic.

[0058] After obtaining various stratum proportion data through step S201, a plurality of stratum elevation / proportion distribution characteristic map sets corresponding to the strata are drawn according to the different deposition and diagenetic environments. The horizontal coordinate of the stratum elevation / proportion distribution characteristic map is the proportion data (unit 0-100%), and the vertical coordinate is the elevation (unit m). For example, the 2# layer of the ZK1 well is sandstone, dense, and the proportion is 20%, and the elevation is -28~ -35m. In the sandstone stratum elevation / proportion distribution characteristic map, the vertical coordinate is -28~ -35m, and the horizontal coordinate is taken to 20% from left to right, thereby a rectangular frame is drawn. The length of the rectangular frame represents the proportion data of the sandstone stratum, and the height of the rectangular frame represents the elevation distribution range of the stratum. The stratum elevation / proportion distribution characteristic maps of other lithologies are drawn in the same way, and a preset number of stratum elevation / proportion distribution characteristic map sets are obtained.

[0059] It should be noted that in this embodiment, different stratigraphic elevation / occupancy distribution characteristic maps need to be drawn for different deposition and diagenetic environments, and one stratigraphic elevation / occupancy distribution characteristic map represents one deposition and diagenetic environment characteristic.

[0060] Step S203: stratigraphic layering and numbering is performed on the stratigraphic elevation / occupancy distribution characteristic map set, and the stratigraphic layering and numbering is mapped to the corresponding strata of all drill holes.

[0061] In step S202, after the stratigraphic elevation / occupancy distribution characteristic map set of different deposition and diagenetic environments is drawn, the stratigraphic layering and numbering is performed mainly on the strata with an occupancy data greater than or equal to a preset occupancy value in each stratigraphic elevation / occupancy distribution characteristic map set, and the stratigraphic layering and numbering is also performed on the strata with an occupancy data less than the preset occupancy value; the stratigraphic layering and numbering is arranged in order of elevation size.

[0062] For example, the stratigraphic layering and numbering is mainly performed on the strata in the 20% occupancy data partition, and the stratigraphic layering and numbering is drawn from the left of the horizontal coordinate, and the strata in the remaining partitions are subdivided according to the main strata, and the strata in the same elevation range are arranged in order of occupancy data size from left to right.

[0063] Step S204: the strata with the same stratigraphic layering and numbering are connected by line segments to generate stratigraphic profile information.

[0064] In this step, all drill holes are projected into the cross-section map according to the set arrangement order, the stratigraphic layering and numbering in step S203 is mapped to the corresponding strata of the drill holes, and the strata with the same stratigraphic layering and numbering in each drill hole are connected by line segments to obtain a geological profile.

[0065] The set arrangement order of the drill holes can be arranged according to actual needs. For example, three drill holes are drilled in a region and are numbered as drill hole 1, drill hole 2, and drill hole 3, the drill holes can be arranged in the order of drill hole 1, drill hole 2, and drill hole 3, or in the order of drill hole 3, drill hole 2, and drill hole 1, if the elevations of drill hole 1 and drill hole 2 are the same and the stratigraphic layering and numbering of the two drill holes are the same from top to bottom, one of drill hole 1 and drill hole 2 can be selected for ordering, and then the arrangement order of the drill holes can be drill hole 1 and drill hole 3.

[0066] Please refer to Figure 2 which is a flowchart of a stratigraphic analysis method according to another embodiment of the present application. The method comprises the following steps:

[0067] Step S301: all drill holes in a target drill hole group are numbered, and the strata of each drill hole are numbered in order from top to bottom; the drill hole number is the initial number in the planar arrangement map of all drill holes in the target drill hole group.

[0068] In this step, taking the XX area XX block as an example, all the drill holes in the target drill hole group in the region are numbered, which is the initial number in the drill hole plan layout. The strata of each drill hole are numbered in order from top to bottom (1-n). For example, as shown in Figure 3 The strata of a certain drill hole ZKS296A in a certain block are numbered as ZKS296A-1, ZKS296A-2, ZKS296A-3, ZKS296A-4, ZKS296A-5, ZKS296A-6, ZKS296A-7, ZKS296A-8, and ZKS296A-9.

[0069] Step S302: Classify all drill hole strata according to the primary and secondary order of rock name, lithology state, color, elevation, and thickness. It includes:

[0070] Drill hole strata with overlapping elevation distribution ranges up to a preset value are classified as the same type. In an embodiment, drill hole strata with larger overlapping elevation distribution ranges are classified as the same type.

[0071] For example, as shown in Figure 4 The target drill hole group of the XX area XX block has a total of 51 drill holes. Due to the limited space Figure 4 in this article, only 34 drill holes of the target drill hole group are shown, and the proportion of the four types of strata is 25.5%, 15.7%, 15.7%, and 9.8%, respectively.

[0072] If the proportion of one type of rock name, lithology state, color, or thickness in all drill hole strata exceeds a preset value, and there are at least two drill hole elevation distribution ranges with no intersection, then the same type is further divided according to the size of the elevation distribution range proportion.

[0073] If the proportion of a certain type of classification exceeds 20%, and there are at least two drill hole elevation distribution ranges with no intersection, then the same type needs to be further divided into two types using a clustering analysis method. For example, one clustering analysis method can use K-means to classify the top and bottom plate elevations of the strata as variables, and the same elevation range is arranged from left to right according to the size of the proportion to divide into the same type. The K-means clustering analysis method uses existing analysis methods, which are not described here.

[0074] Step S303: Obtain the stratum elevation / proportion distribution characteristic map set according to the proportion data and different deposition and diagenetic environments.

[0075] The coordinate system of the stratum elevation distribution characteristic map is constructed, with the vertical coordinate being the elevation and the horizontal coordinate being the area with a proportion of 100%. In this embodiment, according to different diagenetic and depositional environments, eight types of stratum elevation distribution characteristic maps are divided, as follows:

[0076] The first stratum elevation / occupancy ratio distribution feature map: bedrock;

[0077] The second stratum elevation / occupancy ratio distribution feature map: fill;

[0078] The third stratum elevation / occupancy ratio distribution feature map: flow-plastic soft soil;

[0079] The fourth stratum elevation / occupancy ratio distribution feature map: fine sand, silt, and silt;

[0080] The fifth stratum elevation / occupancy ratio distribution feature map: hard-plastic, hard-plastic silty clay, and clay;

[0081] The sixth stratum elevation / occupancy ratio distribution feature map: soft-plastic, soft-plastic silty clay, and clay;

[0082] The seventh stratum elevation / occupancy ratio distribution feature map: pebble and round gravel;

[0083] The eighth stratum elevation / occupancy ratio distribution feature map: block stone and broken stone.

[0084] Step S304: stratifying and numbering the strata in the stratum elevation / occupancy ratio distribution feature map set, including:

[0085] Taking the strata with an occupancy ratio data greater than or equal to a preset occupancy ratio value as the main strata, stratifying and numbering them first, and then stratifying and numbering the strata with an occupancy ratio data less than the preset occupancy ratio value; the stratification and numbering are arranged in order of elevation size.

[0086] In an embodiment of the present application, a pebble and round gravel stratum elevation / occupancy ratio distribution feature map is shown. Please refer to Figure 5 According to the primary and secondary order classification results of the strata in the borehole in terms of rock name, lithology state, color, elevation, thickness, and occupancy ratio data, and in combination with the pebble and round gravel stratum elevation / occupancy ratio distribution feature map, the strata in the pebble and round gravel stratum elevation / occupancy ratio distribution feature map can be stratified and numbered.

[0087] Among them, the strata with an occupancy ratio data greater than or equal to a preset occupancy ratio value are taken as the target division strata, and the preset occupancy ratio value is defined as 20%, that is, the stratification and numbering take the strata in the region with an occupancy ratio data greater than or equal to 20% as the main strata, and divide them into the target division strata. For example Figure 5For example, take the rectangular frame projection of the pebble, gray, dense (25.5%), elevation -68~84m stratum on the pebble, round gravel stratum elevation / occupancy distribution characteristic diagram, from the left of the horizontal coordinate, the rectangular frame length represents the occupancy data 25.5%, and the vertical coordinate represents the elevation -68~-84m; secondly, the pebble, mixed color, dense (15.7%), elevation -68~-84m stratum and the pebble, gray, dense (25.5%), elevation -68~83m stratum have a large overlap in the elevation distribution range, and can be divided into the same elevation range, and thus can be divided into the same stratum.

[0088] The horizontal coordinate of the pebble, mixed color, dense (15.7%), elevation -68~-84m stratum is drawn from 25.5%, and the horizontal coordinate length represents the occupancy data 15.7%. The pebble (containing clay), gray, dense (15.7%), elevation -70~-85m and round gravel, gray, dense (9.8%), elevation -70~-85m have a large overlap in the elevation distribution range with the aforementioned two, and are also divided into the same stratum. The rectangular frame drawing method of the pebble (containing clay), gray, dense (15.7%), elevation -70~-85m and round gravel, gray, dense (9.8%), elevation -70~-85m is similar and will not be repeated here.

[0089] Please refer to Figure 5 In the stratum elevation / occupancy distribution diagram, the stratum is numbered, the stratum in the occupancy data greater than or equal to 20% partition is mainly numbered, the remaining strata are subdivided according to the main stratum, and the same elevation range is arranged from left to right according to the occupancy size, which can be ③4, ⑤4, ⑥4, and can be numbered according to the elevation size in order. The final layered number is shown in Figure 6 .

[0090] Step S305: Map the layered number to the corresponding stratum of all drill holes.

[0091] Please refer to Figure 6 In this step, all drill holes are projected into the section diagram according to the set arrangement order, and all layered numbers in step S303 are correspondingly mapped to the strata corresponding to the drill holes. The layered number can be ①0, ②1, ③1, ④2, ⑤2, ⑥1. For details, refer to the description in step S203.

[0092] Step S306: Arrange all drill holes according to the set order, connect the strata with the same layered number in each drill hole with a line segment, and generate stratum profile information.

[0093] In step S305, after transversely projecting all boreholes according to the number data to the section view and longitudinally projecting according to the mileage, the strata with the same layer number in step S305 are directly connected by line segments to form a geological section, and finally a strata profile is formed. Please refer to Figure 6 The strata profile contains strata elevation, rock name, strata boundary, borehole number and elevation.

The device comprises a first input module 600, a second input module 601, a calculation module 610, a drawing module 620, an editing module 630 and a generation module 640.

[0096] The second input module 601 is used for inputting the rock name, lithology state, color, elevation and thickness index of all boreholes.
