[0028] In order to make the objects, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the drawings.

[0029] The present disclosure provides a visualization method of a three-dimensional geological model, as shown in Figure 1 The visualization method includes:

[0030] S101: Obtain display-related data in model data of a three-dimensional geological model.

[0031] The three-dimensional geological model includes a plurality of grids, and each grid includes a plurality of vertices and a plurality of grid faces. The display-related data includes coordinate data and attribute field data of each grid in the plurality of grids. The coordinate data includes three-dimensional coordinate values of each vertex of the grid in a three-dimensional coordinate system.

[0032] In this embodiment, each grid in the three-dimensional geological model is a parallelepiped, and two adjacent grids are arranged according to the direction of one of the coordinate axes in the three-dimensional coordinate system. The volume of each grid is different. Each grid has eight vertices, and each grid face corresponds to four vertices.

[0033] S102: Determine a grid face to be displayed, the grid face to be displayed including a boundary face and a grid face pair, the boundary face being a grid face of a plurality of grids constituting an outer surface of the three-dimensional geological model, the grid face pair including a first grid face and a second grid face, the first grid face and the second grid face being opposite grid faces between two adjacent grids in the plurality of grids, and the first grid face and the second grid face not being completely coincident.

[0034] The opposite grid faces refer to a face-to-face relationship between a grid face of one of the two adjacent grids and a grid face of the other grid, and the face-to-face relationship can be parallel and spaced apart, coplanar, or spaced apart but not parallel.

[0035] The non-completely coincident refers to a projection of the first grid face on the second grid face being not completely the same as the second grid face.

[0036] S103: Display the three-dimensional geological model according to the attribute field data and the three-dimensional coordinate values of the vertices of the grid face to be displayed.

[0037] The visualization method provided in the embodiments of the present disclosure can avoid displaying the three-dimensional coordinate values of all the vertices when visualizing and displaying the three-dimensional geological model, thereby greatly improving the grid display speed of the three-dimensional geological model and meeting the display needs of the three-dimensional geological model containing tens of millions of grids or more than one hundred million grids.

[0038] Figure 2 is a flowchart of another visualization method of a three-dimensional geological model provided by the embodiments of the present disclosure, which is combined with Figure 2 The determination method comprises:

[0039] S201: Set a mark for display-related data in model data of the three-dimensional geological model.

[0040] The display-related data includes coordinate data and attribute field data of each grid in the plurality of grids, and the coordinate data includes three-dimensional coordinate values of each vertex of the grid in a three-dimensional coordinate system.

[0041] The attribute field data includes attribute data of each grid in the three-dimensional geological model, and is used to reflect geological characteristics, such as the permeability, porosity, and formation pressure of the stratum position corresponding to the grid in the three-dimensional geological model.

[0042] The model data of the three-dimensional geological model further includes fault data, well trajectory data, and the like.

[0043] The mark is used to indicate the start position, data length, and end position of the coordinate data and the attribute field data in the display-related data, so that the coordinate data and the attribute field data of each grid can be quickly located in the loading stage of the model data of the three-dimensional geological model.

[0044] In this embodiment, the mark is realized by separately storing the start position, data length, and end position of the coordinate data and the attribute field data in a file, or storing the start position, data length, and end position of the coordinate data and the attribute field data in the file header of the corresponding model data.

[0045] S202: Obtain display-related data in the model data of the three-dimensional geological model.

[0046] Exemplarily, the display-related data in the model data of the three-dimensional geological model is quickly obtained according to the pre-set mark.

[0047] In this embodiment, in order to facilitate the use of the coordinate data subsequently, the coordinate data is separately stored in the form of an array pointer after the display-related data is obtained, so that the coordinate data can be quickly pointed to according to the array pointer.

[0048] S203: Determine a grid face to be displayed, the grid face to be displayed including a boundary face and a grid face pair, the boundary face being a grid face of a plurality of grids constituting an outer surface of the three-dimensional geological model, the grid face pair including a first grid face and a second grid face, the first grid face and the second grid face being opposite grid faces between two adjacent grids in the plurality of grids, and the first grid face and the second grid face not being completely coincident.

[0049] Exemplarily, step S203 is realized by the following manner:

[0050] 2031: Determine three-dimensional coordinate values of corresponding first and second vertices, the first vertex being a vertex on the first grid face, and the second vertex being a vertex on the second grid face.

[0051] The line segments with the corresponding first and second vertices as end points are respectively located outside the edges of the first and second grid faces, and the line segments are spaced apart from each other without intersection.

[0052] According to the foregoing, each grid face includes four vertices, in order to make the vertices in the first grid face and the second grid face one-to-one corresponding, the positions of the four vertices in the first grid face and the second grid face, i.e., the first and second vertices, need to be determined.

[0053] That is, the first mesh surface includes four first vertices, the second mesh surface includes four second vertices, the four first vertices and the four second vertices are one-to-one corresponding, and the four first vertices and the four second vertices are spaced apart from each other.

[0054] The spacing refers to no intersection, that is, the spacing can be parallel or non-parallel.

[0055] 2032: Obtain the coordinate difference based on the three-dimensional coordinate values of the corresponding first vertex and the second vertex.

[0056] Step 2032 includes:

[0057] First, obtain the two-dimensional coordinate values of the corresponding first vertex and the second vertex based on the three-dimensional coordinate values of the corresponding first vertex and the second vertex. The two-dimensional coordinate values are the coordinate values corresponding to the projections of the first vertex and the second vertex in the coordinate plane. The coordinate plane is formed by two coordinate axes in the three-dimensional coordinate system, and the coordinate plane is opposite to the first mesh surface and the second mesh surface.

[0058] The relative relationship herein refers to the face-to-face relationship as described above, which can be parallel and spaced apart, coplanar, or spaced apart and non-parallel.

[0059] As known from the foregoing, the two adjacent meshes are arranged in the direction of one of the coordinate axes in the three-dimensional coordinate system.

[0060] For the mesh surface pair formed by the two adjacent meshes in the positive direction of the X-axis (generally also referred to as the I direction), the two-dimensional coordinate values of the corresponding first vertex and the second vertex are the coordinate values corresponding to the projections of the first vertex and the second vertex in the YOZ coordinate plane.

[0061] For the mesh surface pair formed by the two adjacent meshes in the positive direction of the Y-axis (generally also referred to as the J direction), the two-dimensional coordinate values of the corresponding first vertex and the second vertex are the coordinate values corresponding to the projections of the first vertex and the second vertex in the XOZ coordinate plane.

[0062] For the mesh surface pair formed by the two adjacent meshes in the positive direction of the Z-axis (generally also referred to as the K direction), the two-dimensional coordinate values of the corresponding first vertex and the second vertex are the coordinate values corresponding to the projections of the first vertex and the second vertex in the XOY coordinate plane.

[0063] Second, the two-dimensional coordinate values of the first vertex and the second vertex are subtracted to obtain the coordinate difference of the vertex.

[0064] For the grid face pair in the positive direction of the X axis, the corresponding coordinate values of the first vertex and the second vertex in the Y axis and the Z axis are subtracted. For the grid face pair in the positive direction of the Y axis, the corresponding coordinate values of the first vertex and the second vertex in the X axis and the Z axis are subtracted. For the grid face pair in the positive direction of the Z axis, the corresponding coordinate values of the first vertex and the second vertex in the X axis and the Y axis are subtracted. In this way, the corresponding coordinate differences can be obtained.

[0065] 2033: Determine the grid face pair based on the coordinate differences and the difference threshold.

[0066] In this embodiment, the grid face pair is determined by comparing the coordinate differences and the difference threshold.

[0067] In response to at least one value in the coordinate differences being greater than the difference threshold, the first grid face and the second grid face are determined as the grid face pair.

[0068] Exemplarily, the difference threshold is proportional to the number of grids in the three-dimensional geological model. The greater the number of grids, the greater the difference threshold. For a three-dimensional geological model including more than ten million grids, the difference threshold is ±0.02.

[0069] Figure 3 is a type diagram of the grid face pair provided by the embodiment of the present disclosure, in combination with Figure 3 , the grid face pair includes six types in the figure. For ease of understanding, the two-dimensional coordinates of the first vertex and the second vertex in the grid face pair on the figure are (x, y).

[0070] The grid face without filling on the figure is denoted as the first grid face, and the grid face with filled shadow graphics is denoted as the second grid face.

[0071] The two-dimensional coordinate values of the corresponding four first vertices in the first grid face are A1(x a1 , y a1 ), B1(x b1 , y b1 ), C1(x c1 , y c1 ), and D1(x d1 , y d1 ), and the two-dimensional coordinates of the corresponding four second vertices in the second grid face are A2(x a2 , y a2 ), B2(x b2 , y b2 ), C2(x c2 , y c2 ), and D2(x d2 , y d2 ).

[0072] Correspondingly, the coordinate difference of the corresponding first vertex and second vertex includes four coordinate values, i.e., (x a1 -x a2 , y a1 -y a2 ), (x b1 -x b2 , y b1 -y b2 ), (x c1 -x c2 , y c1 -y c2 ), (x d1 -x d2 , y d1 -y d2 ).

[0073] Figure 3 In the first case a, four first vertices in the first mesh surface, the vertex on the left upper side (i.e., A1) falls in the second mesh surface, and the other three first vertices are all outside the second mesh surface, at least one of the four coordinate differences is greater than the corresponding threshold difference.

[0074] Figure 3 In the second case b, four first vertices in the first mesh surface, the first vertex on the left lower side (i.e., D1) falls in the second mesh surface, and the other three first vertices are all outside the second mesh surface, at least one of the four coordinate differences is greater than the corresponding threshold difference.

[0075] Figure 3 In the third case c, four first vertices in the first mesh surface, the first vertex on the right upper side (i.e., B1) falls in the second mesh surface, and the other three first vertices are all outside the second mesh surface, at least one of the four coordinate differences is greater than the corresponding threshold difference.

[0076] Figure 3 In the fourth case d, four first vertices in the first mesh surface, the first vertex on the right lower side (i.e., C1) falls in the second mesh surface, and the other three first vertices are all outside the second mesh surface, at least one of the four coordinate differences is greater than the corresponding threshold difference.

[0077] Figure 3 In the fifth case e, four first vertices (i.e., A1, B1, C1, D1) in the first mesh surface all fall in the second mesh surface, at least one of the four coordinate differences is greater than the corresponding threshold difference.

[0078] Figure 3In the sixth case f, none of the four first vertices (i.e., A1, B1, C1, and D1) in the first mesh surface falls in the second mesh surface, and at least one of the four coordinate differences is greater than the corresponding threshold difference.

[0079] S204: Display the three-dimensional geological model according to the attribute field data and the three-dimensional coordinate values of the vertices of the mesh surface to be displayed.

[0080] Step S204 includes:

[0081] 2041: Store the three-dimensional coordinate values of the vertices of the mesh surface to be displayed in a list in units of the mesh surface to be displayed, to obtain a visualization list.

[0082] The visualization list can provide data support for subsequent display of the three-dimensional geological model, so that all mesh surfaces are not displayed as the mesh surface to be displayed, and the display speed of the three-dimensional geological model is improved.

[0083] 2042: Display the three-dimensional geological model according to the visualization list and the attribute field data.

[0084] In this embodiment, the visualization list and the attribute field data are displayed by computer software OpenGL (Open Graphics Library) to obtain the three-dimensional geological model.

[0085] Step 2042 includes:

[0086] First step: Determine the appearance attribute of the grid in which the mesh surface to be displayed is located according to the attribute field data.

[0087] The appearance attribute is the color corresponding to the display of the grid when the three-dimensional geological model is displayed.

[0088] According to the displayed color, the size of the physical property parameters such as porosity and permeability at the stratigraphic position corresponding to the grid can be understood.

[0089] Second step: Obtain the appearance attribute of each mesh surface to be displayed in the visualization list according to the appearance attributes of different grids.

[0090] For any grid, the appearance attributes of all mesh surfaces of the grid are the same and are the appearance attribute of the grid.

[0091] In OpenGL, all geometric primitives (functions used to describe graphics) are defined by vertices, and the appearance attributes of vertices located on different meshes are not completely the same. Therefore, when displaying by using computer software OpenGL, the mesh surface to be displayed is first matched with the corresponding appearance attribute to determine the appearance attribute of the mesh surface to be displayed, so that it can be known that the mesh surface to be displayed is displayed in what color.

[0092] Step 3: Forming a visual vertex array by matching the appearance attributes of different mesh surfaces to be displayed with the visual list.

[0093] When displaying a three-dimensional geological model by using OpenGL, if the corresponding appearance attributes of vertices located on different mesh surfaces are described by calling functions one by one, the overhead is very large, and it is not convenient to manage the vertices of a complex geometric body. Therefore, the visual list and the appearance attributes of different mesh surfaces to be displayed are matched to form a visual vertex array, so as to improve the drawing efficiency.

[0094] Step 4: Displaying the three-dimensional geological model by using the visual vertex array.

[0095] When displaying, the software OpenGL automatically displays different colors according to the different appearance attributes of different mesh surfaces to be displayed.

[0096] When displaying, the glDrawElements function command can be directly called in OpenGL, so that the three-dimensional geological model can be quickly displayed.

[0097] In the embodiment, in order to more quickly display the three-dimensional geological model, the visual vertex array can be extracted and stored for OpenGL display, so that the efficiency can be improved.
