Abstract
Description
Technical Field
[0001] This application relates to the field of computer technology, and in particular to a method and related apparatus for drawing geological profile maps. Background Technology
[0002] A geological profile is a vertical cross-section along a straight line on the Earth's surface, used to show the topographic relief along the profile line.
[0003] In related technologies, the typical process involves conducting on-site exploration of the geological area to be mapped, determining exploration lines, and recording exploration data, including geological and lithological data. The geological profile is then drawn based on this data and the exploration lines. However, a geological profile is a vertical section corresponding to the exploration lines. If it is necessary to draw geological profiles in other straight directions within the same geological area, the exploration lines must be replanned, and relevant geological and lithological data must be recorded.

[0054] As described earlier, research on the creation of geological profiles has revealed that the general approach involves conducting on-site exploration of the geological area to be mapped, determining exploration lines, and recording exploration data, including geological and lithological data. The geological profile is then drawn based on this data and the exploration lines. However, a geological profile is a vertical section corresponding to the exploration lines. If it's necessary to draw a geological profile along other straight lines in the same area, the exploration lines must be re-planned, and the relevant geological and lithological data must be re-recorded. For example, if the exploration line is east-west, exploration must be conducted along that line, exploration data recorded, and then the geological profile drawn. If the new exploration line is north-south, exploration must be conducted again along that north-south line, new exploration data recorded, and then the geological profile drawn. In other words, current techniques cannot quickly generate geological profiles in any direction and are resource-intensive.
[0055] To address the aforementioned problems, this application provides a method and related apparatus for drawing geological profile maps. The method includes: acquiring exploration data and target profile lines for a target geological area; then, based on the exploration data, extracting the target profile lines to obtain a target profile of the target geological area, including elevation lines and depth lines corresponding to multiple geological layers; further converting the elevation lines and depth lines into two-dimensional elevation curves and two-dimensional depth curves, respectively; determining the depth value between the bottom plate of each geological layer and the natural ground surface based on the two-dimensional elevation curves and the two-dimensional depth curves; and finally, drawing a target geological profile map of the target geological area based on the target profile, elevation lines, depth lines, and depth values.
[0056] The exploration data includes relevant data for the target geological area. Through this exploration data, geological data of the target geological area can be obtained, and the target profile can be determined based on the target profile line. When the target profile line changes, there is no need to redetermine the exploration line of the target geological area, saving manpower and resources.
[0057] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0058] See Figure 1 The figure is a flowchart of a method for drawing a geological profile provided in an embodiment of this application.
[0059] Combination Figure 1 As shown in the embodiments of this application, the method for drawing geological profile maps may include:
[0060] S101: Obtain exploration data and target profile lines for the target geological area.
[0061] The target geological region refers to the area corresponding to the geological profile map to be drawn, and the target geological region may include multiple geological layers.
[0062] Exploration data refers to data related to the target geological area, such as lithological data (top and bottom depths of lithological bedding layers), elevation vector map data, depth vector map data, etc., without specific limitations. For example, lithological data are shown in Table 1:
[0063] Table 1: Lithological Data
[0064] 659.74 665.23 fine sandstone 665.23 672.35 mudstone 672.35 689.45 fine sandstone 689.45 695.29 medium sandstone ...... ...... ...... 1032.27 1034.60 siltstone 1034.60 1046.27 basalt
[0065] It should be noted that, in the embodiments of this application, the exploration data can be historical exploration data of the target geological area or real-time exploration data, and is not limited to exploration data of the exploration line. It can be all exploration data of the target geological area, and no specific limitation is made here.
[0066] Elevation vector map data refers to the set of vector maps of the plumb line distance from the preset ground surface to the geoid in a target geological area, which is also the set of vector maps of the elevation lines of the target geological area.
[0067] Burial depth vector map data refers to a collection of vector maps showing the burial depths of multiple geological layers within a target geological region.
[0068] In the elevation vector map and the burial depth vector map, each location on the plane indicates a three-dimensional data point. Clicking on any location in the map will retrieve the corresponding three-dimensional data.
[0069] See Figure 2a This figure is a schematic diagram of an elevation vector diagram provided in an embodiment of this application.
[0070] Elevation vector data points can be represented by coordinates (x, y, z), where x and y are the horizontal and vertical coordinates, respectively, and can be in any form, such as latitude and longitude coordinates, 80° coordinates, etc., and z is the elevation, in meters. Combined with... Figure 2a As shown, assuming point A in the image is clicked, the corresponding elevation vector data point for point A is (456000, 2782000, 1150). It should be understood that the embodiments provided in this application... Figure 2a This is just an example.
[0071] See Figure 2b This figure is a schematic diagram of a burial depth vector diagram of a certain stratum provided in an embodiment of this application.
[0072] The representation of burial depth vector data points is similar to that of elevation vector data points; they can also be represented by coordinates (x, y, z). Here, x and y have the same meaning as x and y in elevation vector data points, i.e., x and y are the horizontal and vertical coordinates, respectively, and can be in any form, such as latitude and longitude coordinates, 80° coordinates, etc. z represents the burial depth in meters. Figure 2b As shown in the figure, if you click on point B in the figure, the burial depth vector data point corresponding to point B can be (457000, 2782000, 725).
[0073] It should be noted that, in this embodiment of the application, by obtaining the exploration data of the target geological area, information such as the number of geological layers, elevation data, and the burial depth of each geological layer can be obtained, which is convenient for subsequent drawing of geological profile maps.
[0074] The target profile line refers to the profile line corresponding to the geological profile to be drawn. The target profile line can be a profile line in any direction of the target geological area.
[0075] S102: Based on the exploration data, the target profile line is drawn to obtain the target profile of the target geological area.
[0076] The target profile refers to the profile obtained by pulling the target profile line under the layers of elevation vector map data and burial vector map data in the exploration data.
[0077] The target profile includes elevation lines and burial depth lines corresponding to the multiple geological layers, as detailed in [reference needed]. Figure 2c The figure is a schematic diagram of a target cross-section provided in an embodiment of this application.
[0078] Combination Figure 2c As shown, the target profile includes elevation lines and contour lines corresponding to the burial depth of each of the multiple geological layers, as well as the number of geological layers, but does not indicate the burial depth of each of the multiple geological layers.
[0079] The elevation line is the plumb distance from a preset ground point in the target geological area to the geoid; the burial depth line is the plumb distance from the bottom plate of each geological layer in the multi-layered geological system to the natural ground.
[0080] It should be noted that the elevation vector map data includes the elevation vector map corresponding to the target geological area; the elevation line is obtained through the elevation vector map data; and the burial depth line is obtained through the burial depth vector map data.
[0081] S103: Convert the elevation line and the burial depth line into two-dimensional elevation curves and two-dimensional burial depth curves, respectively.
[0082] In this embodiment, the obtained elevation lines are transformed into two-dimensional elevation curves As(x,y), and the burial depth lines of each geological stratum's base are transformed into two-dimensional elevation curves A. i (x,z i Let ), i = 1, 2, 3...n; where x is the distance from the target point on the profile line to a, y represents the elevation, z represents the burial depth corresponding to the target point, and n represents the number of strata. Since n strata are divided according to different depths, there are n two-dimensional burial depth curves.
[0083] The depth values between each geological layer and the natural ground can be obtained using two-dimensional elevation curves and two-dimensional burial depth curves.
[0084] For example, see Table 2, which shows the relationship between the x and y coordinates of a two-dimensional elevation curve As:
[0085] Table 2: As Values for Two-Dimensional Elevation Curves
[0086] y 1150 1200 1250 1300 1350 1400
[0087] Table 2 above shows the relationship between the distance x from the target point on the profile line to point a and the elevation y. Furthermore, based on this table of elevation two-dimensional curve As values, the elevation two-dimensional curve As can be determined. For details, please refer to... Figure 2d As shown in the figure, this figure is a schematic diagram of a two-dimensional elevation curve provided in an embodiment of this application.
[0088] It should be understood that, based on Table 2 above, a two-dimensional elevation curve As can be drawn, combined with... Figure 2d As shown, the two-dimensional elevation curve As can be represented as y = 5E - 11x 4 -1E-07x 3 +0.0001x 2 +0.12x+1150.1.
[0089] For example, see Table 3, which shows the relationship between x and z in a two-dimensional curve of the burial depth of a geological layer:
[0090] Table 3: Two-Dimensional Curve Values for Burial Depth
[0091] z 850 800 750 700 650 600
[0092] Table 3 above shows the relationship between the distance x from the target point to 'a' in a certain geological layer and the burial depth z. Furthermore, based on this burial depth two-dimensional curve value table, the burial depth two-dimensional curve can be determined. For details, please refer to... Figure 2e As shown, this figure is a schematic diagram of a two-dimensional burial depth curve provided in an embodiment of this application. Combined with... Figure 2e As shown, the two-dimensional curve for this burial depth can be z = -3E-11x 4 +1E-07x 3 -0.0001x 2 -0.0682x+849.91.
[0093] S104: Determine the burial depth value between the bottom plate of each geological layer and the natural ground surface in the multi-layered geological layers based on the elevation two-dimensional curve and the burial depth two-dimensional curve.
[0094] It should be noted that, in this embodiment of the application, the two-dimensional elevation curve and the two-dimensional burial depth curve determined in step S103 are plotted in the same coordinate system. The elevation two-dimensional curve of the bottom plate of each geological layer is obtained by calculation, and the elevation coordinate set Aui(x,u) of the bottom plate of the geological layer is obtained by calculating the coordinate set. iLet i = 1, 2, 3...n, x be the distance from the target point on the profile line to a, y be the elevation of the base plate at a certain point, and u be equal to the ground elevation y corresponding to point x minus the burial depth z of the geological layer base plate corresponding to point x. For example, the distance u3 between the third geological layer and the ground is equal to the elevation y3 of the third geological layer minus the burial depth z3 of the third geological layer, that is, u3 = y3 - z3.
[0095] S105: Draw a target geological profile map of the target geological area based on the target profile, the elevation line, the burial depth line and the burial depth value.
[0096] It should be understood that, in the embodiments of this application, the target geological profile is obtained by determining the target profile as the basis for the target geological profile map, and drawing it in combination with elevation lines, burial lines, and burial values. For details, please refer to... Figure 3 The figure is a schematic diagram of a geological profile provided in an embodiment of this application. That is, it can realize the drawing of geological profiles of any section, saving manpower and material costs.
[0097] The method for drawing geological profile maps provided in this application involves acquiring exploration data and target profile lines for a target geological area, then extracting the target profile lines based on the exploration data to obtain a target profile of the target geological area, including elevation lines and depth lines corresponding to multiple geological layers. The elevation lines and depth lines are further converted into two-dimensional elevation curves and two-dimensional depth curves, respectively. The depth value between the bottom plate of each geological layer and the natural ground surface is determined based on the two-dimensional elevation and depth curves. Finally, a target geological profile map of the target geological area is drawn based on the target profile, elevation lines, depth lines, and depth values. The exploration data includes relevant data for the target geological area. This exploration data allows for the acquisition of geological data for the target geological area, and the target profile is determined based on the target profile lines. When the target profile lines change, there is no need to redetermine the exploration lines for the target geological area, saving manpower and resources.
[0098] Based on the geological profile drawing method provided in the above embodiments, to further illustrate the process of obtaining elevation vector map data, as a possible implementation, the elevation vector map data is specifically obtained in the following way:
[0099] A1: Obtain borehole data and burial depth data of the base plate corresponding to the target geological area and multiple geological layers.
[0100] As an example, borehole data may include borehole location coordinates, lithology of borehole cores and corresponding thickness, etc., without being specifically limited here.
[0101] A2: Determine the vector elevation line based on the borehole locations in the borehole data.
[0102] A3: Draw an elevation vector map based on the vector elevation line and the burial depth data of the base plate.
[0103] It should be noted that, in this embodiment of the application, if the historical elevation vector map data of the target geological area is included, the historical elevation vector map data can be directly used as the current elevation vector map data of the target geological area; if only borehole data and the burial depth data of the base plate corresponding to multiple geological layers are included, then an elevation vector map is drawn based on the borehole data and the burial depth data of the base plate, and this elevation vector map is used as the elevation vector map data; if only borehole data is included, an elevation vector map can be drawn based on the elevation data of the borehole points, and used as the elevation vector map data.
[0104] In another possible implementation, the elevation vector map data is obtained specifically through the following method:
[0105] B1: Obtain the non-vector elevation lines and contour maps of the burial depth of the base plate corresponding to the multiple geological layers in the target geological area.
[0106] B2: Draw an elevation vector map based on the non-vector elevation line and the contour map of the burial depth of the base plate.
[0107] It should be noted that if any of the following is not included: historical elevation vector map data, borehole data, or bottom burial depth data corresponding to multiple geological layers, then an elevation vector map can be drawn based on the non-vector elevation lines of the target geological area and the bottom burial depth contour maps corresponding to multiple geological layers.
[0108] It should be understood that non-vector graphics are intuitively similar to vector graphics. Figure 1 While they appear identical, it's impossible to visually determine the data points at each location on the plane. In a non-vector map of ground elevation, the elevations on contour lines can be identified, but the blank areas outside the contour lines don't provide intuitive 3D data; interpolation or other methods are needed to obtain the data for these blank areas.
[0109] Based on the geological profile drawing method provided in the above embodiments, in order to improve the richness of the geological profile, as a possible implementation method, before step S103, the method may further include:
[0110] Obtain the fault coordinates of the target geological area; the fault coordinates are the coordinates in the target profile where the difference between the longitudinal coordinate value and the adjacent longitudinal coordinate value is greater than a preset value.
[0111] It should be noted that due to the complex geology, there may be fault areas. Therefore, the location where the vertical coordinate of the target profile changes abruptly can be taken as the location of the fault development. The horizontal coordinate of this point is recorded to obtain the fault coordinate.
[0112] Correspondingly, step S105 may include: drawing a target geological profile map of the target geological area based on the fault coordinates, the target profile, the elevation line, the burial depth line, and the burial depth value.
[0113] Based on the geological profile drawing method provided in the above embodiments, in order to improve the richness of the geological profile, in another possible implementation, before step S103, the method may further include:
[0114] Obtain the borehole coordinates of the target geological area; the borehole coordinates are obtained based on the borehole data corresponding to the target geological area.
[0115] It should be noted that if there is borehole data on the target profile line, the coordinates of multiple borehole points will be marked on the curve using different symbols.
[0116] Correspondingly, step S105 may include:
[0117] A target geological profile map of the target geological area is drawn based on the borehole coordinates, the target profile, the elevation line, the burial depth line, and the burial depth value.
[0118] In another possible implementation, different content can be marked on the target profile. For example, if you want to study the laws related to groundwater chemistry, you can mark points with water chemistry parameters such as wells and springs; if you want to study the enrichment laws of gases such as shale gas and coalbed methane, you can mark gas well locations; if you want to study the migration and dispersion laws of oil and gas, you can mark points with parameters such as porosity, permeability, and oil and gas content.
[0119] See Figure 4 This figure is a flowchart of another method for drawing a geological profile provided in an embodiment of this application.
[0120] It should be noted that, in the embodiments of this application, geological profile maps can be drawn using drawing software. The following section uses ArcMAP as an example, combined with... Figure 4 As shown in the embodiments of this application, the method for drawing geological profile maps may include:
[0121] S401: Add exploration data to the software.
[0122] As an example, Arc MAP software can add elevation vector map data of the target geological area, as well as burial vector map data of the base plate of multiple geological layers.
[0123] S402: Use software to draw ground elevation lines and the burial depth lines of the base plate of multiple geological layers.
[0124] First, use the tools in Arc MAP software to pull the target profile line ab. At this time, the base data is the elevation vector map data. Then, output the target profile map, which will give you the target profile map containing the target elevation line.
[0125] Furthermore, the target profile line ab is drawn again using the tools in Arc MAP software. The base data at this time is the burial depth vector map data, from which the burial depth contour lines of the bottom plate of each geological layer can be obtained. Assuming that there are 4 existing geological layers, the burial depth lines of the bottom plate of the geological layers in the target profile map from bottom to top are labeled as D1, D2, D3, and D4 respectively.
[0126] S403: Mark faults and other geographic information.
[0127] Mark the coordinates of the locations where the vertical coordinates of the target profile change abruptly, and the coordinates of the coalbed methane well points on the target profile line ab. Mark all coordinates on the curve with different symbols.
[0128] S404: Convert the elevation line and burial depth line into two-dimensional elevation curves and two-dimensional burial depth curves, respectively.
[0129] The obtained elevation lines are transformed into two-dimensional elevation curves As(x,y), and the burial depth lines of the bottom plate of each geological layer are transformed into two-dimensional burial depth curves Ai(x,zi), i=1,2,3,4, where x is the distance from a point on the profile line to a, y represents the elevation, and z represents the burial depth.
[0130] S405: Calculate the burial depth of the bottom plate of the geological layer.
[0131] The elevation of the bottom plate of the geological layer is obtained by calculating the coordinate set. The two-dimensional curve Aui(x,ui), i=1,2,3,4, where x represents the elevation of the bottom plate at a certain point, and u is equal to the ground elevation y corresponding to x minus the burial depth z of the bottom plate of the geological layer corresponding to x.
[0132] S406: Draw the geological profile of the target.
[0133] Draw elevation lines and two-dimensional elevation curves of the base plate of each geological layer, and mark the location coordinates on the curves. Classify faults according to the fault distance of geological layers, and connect the fault points of adjacent layers to draw complete faults. The borehole lithology and gas content can be marked on the target geological profile map, which clearly identifies which structural parts are gas-rich areas, facilitating the precise exploration and development of shale gas, coalbed methane, etc.
