Description

Technical Field

[0075] The present invention will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0076] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0077] The first embodiment of the present invention provides a method for densifying a geological cross-section diagram. The following will be described in detail in conjunction with Figure 1 and Figure 2 for detailed description.

[0078] As Figure 1 shown, in step S1, a geological cross-section diagram is obtained, and the geological cross-section diagram contains the formation stratification information of different boreholes.

[0079] Specifically, there are various methods for obtaining the geological cross-section diagram data, such as hand-drawing, using professional software to draw, collecting other cross-section diagram materials, etc. Regardless of which data acquisition method is used, the most original data source is: obtaining single-point formation information through field exploration, and obtaining the geological cross-section diagram through the projection of exploration points and connecting layers of formation lines.

[0080] As Figure 1 shown, in step S2, stretching and densifying transformation is performed on the borehole spacing, borehole depth, and borehole layer thickness included in the geological cross-section diagram.

[0081] The above steps specifically include:

[0082] Step S21, performing stretching and densifying transformation on the borehole spacing, including the following steps:

[0083] Calculate the horizontal spacing between adjacent boreholes on the cross-section diagram, and arrange them in sequence to form a borehole spacing matrix x1:

[0084]

[0085] where n is the number of boreholes;

[0086] Generate a random encryption matrix A for the horizontal spacing of boreholes using a random number generation algorithm:

[0087]

[0088] Perform a linear stretching or compression transformation on the borehole spacing using the random encryption matrix A, that is, obtain the stretched or compressed borehole spacing matrix x2 by calculating the Hadamard product of the random matrix A and the borehole spacing matrix x1:

[0089]

[0090] Update the borehole spacing in the geological section diagram according to the values in the stretched or compressed borehole spacing matrix x2.

[0091] As Figure 3 shown, this example geological section diagram has a total of three boreholes ZK1, ZK2, and ZK3, and the horizontal spacings of the boreholes are 39 and 40 respectively, denoted as Figure 3 There are a total of three boreholes, and there are 2 spacings between adjacent boreholes. Therefore, the generated random matrix contains 2 data, and the generated random matrix All data in matrix A are in the range (0, 2). Using to Figure 3 stretch or compress the borehole spacing. The original borehole spacing is The Hadamard product (multiplying the data at corresponding positions) of the two matrices is calculated to obtain the stretched borehole spacing After transformation, as Figure 4 shown.

[0092] Step S22: Perform a stretching and encryption transformation on the borehole depth, including the following steps:

[0093] Record the depths of all boreholes on the geological section diagram as matrix x3:

[0094]

[0095] where n is the number of boreholes;

[0096] Generate a random encryption matrix B for the borehole depth using a random number generation algorithm. The random matrix B has 1 column and n rows:

[0097]

[0098] Correct the borehole depths using the random encryption matrix B. After correction, the depths of all boreholes are:

[0099]

[0100] Denote the depth of each stratum layer of the \(i\)-th borehole as follows:

[0101]

[0102] \(m\) is the number of stratum layers of the \(i\)-th borehole;

[0103] Modify the depth of the \(i\)-th borehole using the \(i\)-th element of matrix \(B\). After modification, the depths of each layer of the \(i\)-th borehole are:

[0104]

[0105] Then, modify the depths of all borehole layers on the cross-section diagram in sequence to obtain the modified stratum depth. Figure 4 In the example geological cross-section diagram, there are a total of 3 boreholes, and there are a total of three elements in the generated random matrix \(B\). Example geological cross-section diagram borehole depth Using the random matrix Modified borehole depth The depth of the ZK1 layer is shendu1 = Using The first data 1.2 for correction, after correction The depth of the ZK2 layer is Using The second data 0.9 for correction, after correction The depth of the ZK3 layer is Using The third data 1.2 for correction, after correction The cross-section diagram after the scaling transformation is as Figure 5 shown.

[0106] Step S23, correction of the inter-borehole stratum line. The inter-borehole stratum nodes are divided into two categories: lenticular stratum nodes and annihilation stratum nodes. The closed stratum area formed by the connection of the stratum line with a single borehole is defined as a lenticle. The intersection of the stratum line with other stratum lines between boreholes is defined as stratum annihilation.

[0107] (1) For the lenticular stratum, use the borehole depth correction coefficient corresponding to the lenticular stratum in the randomly encrypted matrix \(B\) of the borehole connected to the lenticular stratum to modify the depth of the lenticular stratum nodes located between the boreholes, and obtain the modified lenticular stratum line.

[0108] As Figure 5 shown in, the karst stratum of ZK2 is a lenticle, and the stratum nodes 1 and 2 marked with red circles are the lenticle nodes to be scaled and transformed. From Figure 4The initial buried depths of Node 1 and Node 2 are 30 and 30 respectively. After being corrected by the depth correction coefficient of 0.9 for ZK2, the buried depths become 27 and 27. The cross-sectional view after the lens body correction is as Figure 6 shown.

[0109] (2) For the annihilated formation, first determine which formation line the formation annihilation body annihilates on, and record the corresponding formation line as L1. Then, vertically move the annihilated formation nodes between the boreholes up and down so that the corresponding annihilated formation nodes fall on the formation line L1, thereby obtaining the corrected annihilated formation line.

[0110] As Figure 5 shown, the node 3 marked by the red circle in it is the formation annihilation point. From Figure 4 it can be seen that this formation line was originally annihilated on the upper formation line. Therefore, vertically move this annihilation node so that the annihilation node falls on this formation line again, thereby obtaining the corrected formation line of the annihilation body. The partial enlarged views before and after the correction of the annihilated formation are shown in Figure 7 . The geological cross-sectional view after the lens body correction and the annihilated formation correction is shown in Figure 8 .

[0111] Step S24, perform stretching, densifying, and transformation on the layer thickness of the boreholes, including the following steps:

[0112] For any borehole i on the modified geological cross-sectional view, record the matrix of the layer thicknesses of each formation on the borehole as:

[0113]

[0114] where m is the number of formation layers of borehole i;

[0115] Use the random number generation algorithm to generate the random densifying matrix C i of the layer thicknesses of each formation of the borehole:

[0116]

[0117] Use the random densifying matrix C i and the layer thickness matrix dchd i to calculate the Hadamard product to obtain the densified layer thickness:

[0118]

[0119] Then, sequentially densify the layer thicknesses of all boreholes to obtain the geological cross-sectional view with randomly densified layer thicknesses.

[0120] Figure 8 In for ZK1, record the layer thickness from top to bottom, For ZK3, record the formation thickness from top to bottom. The corrected geological cross-section is as Figure 9 shown.

[0121] Step S25, re-correction of the inter-borehole formation line.

[0122] (1) For the lenticular formation, first calculate the average of the top depth and the bottom depth of the lenticular formation, and then take the average value as the annihilation depth of the lenticular formation.

[0123] Figure 9 In, the karst cave of ZK2 is a lenticle, the top depth is 24.93, the bottom depth is 26.73, and the average value is (24.93 + 26.73) / 2 = 25.8. Thus, the annihilation depth of the lenticle is corrected to 25.8, and the corrected geological cross-section is Figure 10 .

[0124] (2) For the annihilated formation, first determine which formation line the formation annihilation body annihilates on, and record the corresponding formation line as L2. Then, vertically move the annihilated formation nodes between the boreholes up and down so that the corresponding annihilated formation nodes fall on the formation line L2, thereby obtaining the corrected annihilated formation line.

[0125] Figure 9 In, the gravel soil formation line is annihilated upward and annihilates on the formation boundary between the silty clay and the limestone. Therefore, Figure 10 In, the annihilated formation nodes are vertically moved downward to the formation boundary between the silty clay and the limestone to obtain the corrected geological cross-section of the annihilated formation.

[0126] As Figure 1 shown, in step S3, the identification annotation information included in the geological cross-section is encrypted to obtain the final encrypted geological cross-section.

[0127] Specifically, in addition to the boreholes, formation boundaries, formation patterns, and formation descriptions on the cross-section, it also includes the water level line, in-situ test markings, sampling symbol markings, weathering line markings, etc. Except for the boreholes, formation boundaries, formation patterns, and formation descriptions, other information on the cross-section is deleted. Thus, the final encrypted geological cross-section is obtained.

[0128] In the above example cross-section, for the convenience of demonstration, there are no information markings such as sampling symbols, water level lines, and weathering lines. Therefore Figure 11 is the final encrypted geological cross-section.

[0129] In addition, it should be noted that the present invention can use any random number generation algorithm to generate random numbers; and the representation methods of each matrix in the present invention can be replaced by any other symbols, and the above symbols are only used for the convenience of explaining the logical relationship.
