Description

Technical Field

[0001] This invention relates to the field of geophysical exploration technology, specifically to a data display method, apparatus, electronic device, and readable storage medium. Background Technology

[0002] With the continuous deepening of exploration work and the rapid development of methods and technologies, the quantity and speed of geological information collection have been greatly improved. Oil and gas exploration data are increasingly characterized by large data volume and complex and diverse types, which also brings challenges to the interpretation and analysis of data. The integration of seismic geology and engineering requires reference to a large amount of surface collection information in pre-drilling engineering such as well site selection and surface engineering construction.

[0003] Existing technologies mainly focus on surface and image data management. GeoEast software can use multiple modules to load geological stratigraphic data, but for hundreds of gigabytes of data, it often uses thinning methods, which cannot load massive amounts of geological stratigraphic data with high precision and has low display efficiency. Summary of the Invention

[0024] Optionally, the step of interpolating the cavity point based on the values ​​of adjacent layer points includes:

[0025] Add all void points to the preset queue;

[0026] If the preset queue is not empty, the interpolation process is performed sequentially on each empty point in the preset queue.

[0027] Once the interpolation of the first void point is completed, the first void point is removed from the preset queue;

[0028] If the interpolation of the first void point is not completed, the first void point is added to the tail of the preset queue;

[0048] Method Implementation Examples

[0049] The data display method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0050] Reference Figure 1 , Figure 1 This application provides a flowchart illustrating the steps of a data display method according to an embodiment of the present application. Figure 1 As shown, the method specifically includes the following steps:

[0051] Step S101: Obtain geological stratigraphic data of the target area.

[0052] Geological stratigraphic data refers to data reflecting the undulations and structure of geology, obtained through the interpretation of data obtained during geological exploration. Specifically, geological stratigraphic data includes: surface data and subsurface data.

[0053] Geological stratigraphic data can be obtained in various ways, and this embodiment of the invention does not impose specific limitations. For example, before obtaining the geological stratigraphic data, the method may further include: converting seismic data into geological stratigraphic data through methods such as seismic stratigraphic interpretation and extraction of stratigraphic attributes; or directly importing the interpreted geological stratigraphic data.

[0054] The data display method provided in this invention can be applied to the field of massive data management, enabling unified management and analysis of geological stratigraphic data composed of massive above-ground and underground data, and displaying it in the form of images.

[0055] Step S102: Based on the first horizontal axis coordinate and the first vertical axis coordinate of the stratum point in the geological stratum data, determine the second horizontal axis coordinate and the second vertical axis coordinate of the stratum point in the model coordinate system.

[0056] It should be noted that geological stratigraphic data includes surface data and subsurface data. The coordinate systems of the surface data and subsurface data can be the same or different. If the coordinate systems of the surface data and subsurface data are different, the surface data and subsurface data will be unified into the same coordinate system.

[0057] For example, surface data is typically based on latitude and longitude coordinates in the Earth coordinate system, while subsurface stratigraphic data is typically based on the geodetic coordinate system. When the surface and subsurface data reside in different coordinate systems, the latitude and longitude coordinates of the surface data are transformed to the geodetic coordinate system. Then, based on the first horizontal and first vertical coordinates of the stratigraphic point in the geodetic coordinate system, the second horizontal and second vertical coordinates of the stratigraphic point in the model coordinate system are determined. Specifically, by performing linear transformations such as scaling, rotation, and translation on the first horizontal and first vertical coordinates of the stratigraphic point in the geological stratigraphic data, the second horizontal and second vertical coordinates of the stratigraphic point in the model coordinate system are obtained.

[0058] Step S103: Determine the depth characteristics of the stratum location based on the vertical axis coordinates of the stratum location in the geological stratum data.

[0059] It should be noted that the layer points correspond to three-dimensional coordinate data, including: horizontal axis coordinates, vertical axis coordinates, and vertical axis coordinates. A two-dimensional array is constructed based on the horizontal and vertical axis coordinates of all layer points; the vertical axis coordinates of all layer points are added to a one-dimensional array. The two-dimensional array reflects the position of all layer points on the same plane, and the vertical axis coordinates reflect the depth characteristics of the layer points.

[0060] Step S104: Based on at least two resolutions, downsample the coordinate data of each layer point in the model coordinate system at least twice to obtain at least two data matrices.

[0061] It should be noted that once the x-axis and y-axis coordinates of all layer points in the model coordinate system are determined, these coordinates can form an initial two-dimensional data matrix. The resolution corresponding to this initial two-dimensional data matrix is ​​set as the initial resolution. Downsampling of the initial two-dimensional data matrix yields a two-dimensional data matrix with reduced resolution.

[0062] Downsampling can be performed in various ways, and this embodiment of the invention does not limit the specific methods used. For example, the user presets a sampling rate and uses uniform downsampling or random downsampling to downsample the initial two-dimensional data matrix.

[0063] In this embodiment of the invention, the number of resolutions and the value of the resolutions preset by the user are equivalent to the number of downsampling times preset by the user. For example, N different resolutions are preset, and the initial two-dimensional data matrix is ​​downsampled N times to obtain N data matrices with different resolutions. The initial two-dimensional data matrix is ​​then added to the original data matrix, resulting in a total of N+1 data matrices with different resolutions.

[0064] Optionally, an index can be created for each data matrix based on its row and column range, so that the corresponding data matrix can be quickly accessed through the index.

[0065] Step S105: Based on the size and scaling ratio of the preset display area, determine the first data matrix whose resolution meets the preset requirements from the at least two data matrices.

[0066] The preset display area is used to display the image obtained based on the data matrix. The shape of the display area can be polygonal, circular, etc. The size of the preset display area is measured in pixels, and there is a positive correlation between the size of the preset display area and the number of pixels it can display. The larger the size of the preset display area, the more pixels it can display.

[0067] The scaling factor is used to quantify the degree to which the data matrix is ​​reduced or enlarged. The scaling factor can range from negative integers to 0 and positive integers. For example, a scaling factor of 0 means no reduction or enlargement is performed on the data matrix; a scaling factor greater than 0 means the data matrix is ​​enlarged; and a scaling factor less than 0 means the data matrix is ​​reduced. The number of scaling factors is equal to the number of data matrices obtained after sampling the coordinate data of each layer point in the model coordinate system in step S104. For example, if N+1 data matrices are obtained in step S104, then the scaling factor corresponds to N+1 values.

[0068] It should be noted that the display resolution is determined based on the size of the preset display area. When the scaling ratio is set to 0, a display resolution equal to the number of pixels that the preset display area can display is determined based on the size of the preset display area. Based on the display resolution, a third data matrix with a resolution equal to the display resolution is selected from all data matrices obtained in step S104. A scaling ratio greater than 0 means that the third data matrix is ​​enlarged; a scaling ratio less than 0 means that the third data matrix is ​​reduced. The display resolution is less than or equal to the initial resolution in step S104. A second resolution is determined based on the preset display area size and the scaling ratio of the third data matrix, and a data matrix with a resolution equal to the second resolution is selected from all data matrices obtained in step S104. Specifically, after the second resolution is determined, the data matrix with a resolution equal to the second resolution is called as the first data matrix that meets the preset requirements through the corresponding index.

[0069] Step S106: Render the first data matrix with color according to the depth features to obtain the geological stratum image corresponding to the geological stratum data.

[0070] Color is described using the RGB color model, which uses three values ​​(r, g, b) to describe a color. A mapping relationship is established between the feature values ​​of depth features and (r, g, b). For example, the feature values ​​are divided into multiple intervals, with different intervals corresponding to different (r, g, b) values. Different colors are assigned to different depth points in the image, making it easier for users to view the trends of geological undulations.

[0071] Step S107: Display the geological stratum image in the display area.

[0072] It should be noted that, in this embodiment of the invention, the data matrix obtained in step S104 is written into the same file. Based on the size of the preset display area (view display window) in the interactive interface and the scaling ratio, the required resolution level is determined, and the level parameter is passed to the function that retrieves the data matrix. The corresponding data matrix is ​​then retrieved through the function and displayed as image data. For example, Figure 2 This is a geological stratum image based on data from a portion of the geological strata.

[0073] In this embodiment of the invention, geological stratigraphic data of the target area is acquired, including surface data and subsurface data. Based on the first horizontal and first vertical coordinates of the stratigraphic points in the geological stratigraphic data, the second horizontal and second vertical coordinates of the stratigraphic points in the model coordinate system are determined, achieving integrated management of above-ground and subsurface data. Based on the vertical coordinates of the stratigraphic points in the geological stratigraphic data, the depth characteristics of the stratigraphic points are determined, converting the three-dimensional data into two-dimensional data. Based on at least two resolutions, the coordinate data of each stratigraphic point in the model coordinate system are downsampled at least twice to obtain at least two data matrices. According to the size and scaling ratio of the preset display area, a first data matrix whose resolution meets the preset requirements is determined from the at least two data matrices, satisfying the user's needs for images of different clarity. Color rendering is performed on the first data matrix based on the depth characteristics to obtain a geological stratigraphic image corresponding to the geological stratigraphic data, so that different depth feature numerical ranges correspond to different colors, facilitating intuitive understanding and analysis of geological data by the user.

[0074] Optionally, determining a first data matrix whose resolution meets preset requirements from the at least two data matrices based on the size and scaling ratio of the preset display area includes:

[0075] Step 11: Determine the first resolution based on the width and height of the preset display area and the scaling ratio;

[0076] Step 12: Determine the data matrix with the first resolution from the at least two data matrices as the second data matrix;

[0077] Step 13: The user selects a sub-data matrix from the second data matrix, and crops the data in the second data matrix other than the sub-data matrix to obtain the first data matrix; the resolution of the sub-data matrix is ​​equal to the number of pixels that the preset display area can display.

[0078] The width and height of the preset display area are in pixels. The first resolution consists of two parts (best_image_width, best_image_height). best_image_width refers to the number of pixels in the horizontal direction of the image, and best_image_height refers to the number of pixels in the vertical direction of the image. The product of best_image_width and best_image_height equals the total number of pixels contained in the image.

[0079] It should be noted that the first resolution is determined by the product of the width, height and scaling ratio of the preset display area; specifically, the width of the preset display area and n raised to the power of the scaling ratio are used to determine the number of pixels in the horizontal direction in the first resolution; the height of the preset display area and n raised to the power of the scaling ratio are used to determine the number of pixels in the vertical direction in the first resolution.

[0080] The formula for determining the first resolution is as follows:

[0081] best_image_width=viewport_width×n zoom_level (1)

[0082] best_image_height=viewport_height×n zoom_level (2)

[0083] In equations (1) and (2), viewport_width refers to the width of the preset display area, viewport_height refers to the height of the preset display area, and zoom_level refers to the scaling ratio. The value of n is a positive integer greater than 1, such as 2, 3, 4, etc. In general, n is set to 2.

[0084] As can be seen from equations (1) and (2), when the scaling ratio increases, the first resolution increases accordingly. Since the size of the preset display area remains unchanged, the information displayed in the preset display area is more detailed and more local. When the scaling ratio decreases, the first resolution decreases accordingly. Since the size of the preset display area remains unchanged, the information displayed in the preset display area is coarser and more macroscopic.

[0085] It should be noted that if the resolution of the second data matrix is ​​greater than the number of pixels that the preset display area can display, the user can manually select a sub-data matrix from the second data matrix to be displayed in the preset display area. The resolution of the sub-data matrix is ​​equal to the number of pixels that the preset display area can display. After selecting the sub-data matrix, the data in the second data matrix other than the sub-data matrix is ​​cropped to ensure that the displayed data can completely and accurately reflect the geological stratigraphic information.

[0086] In this embodiment of the invention, a first resolution is determined based on the width, height, and scaling ratio of a preset display area. A second data matrix is ​​defined from at least two data matrices that have the first resolution. The size and scaling ratio of the preset display area are set by the user to meet the user's needs for images of different resolutions. The user selects a sub-data matrix from the second data matrix, and the data in the second data matrix excluding the sub-data matrix is ​​cropped to obtain a first data matrix, thus meeting the user's needs for data at different positions within the second data matrix.

[0087] Optionally, determining the second horizontal and second vertical coordinates of the stratum point in the model coordinate system based on the first horizontal and first vertical coordinates of the stratum point in the geological stratigraphic data includes:

[0088] Step 21: Select at least three stratigraphic points from the geological stratigraphic data, and set the first position of the at least three stratigraphic points in the model coordinate system;

[0089] Step 22: Determine the correspondence between the initial coordinate system and the model coordinate system based on the second position and the first position of the at least three layer points in the initial coordinate system;

[0090] Step 23: Based on the first horizontal axis coordinate and the first vertical axis coordinate of the stratum point in the geological stratum data and the corresponding relationship, determine the second horizontal axis coordinate and the second vertical axis coordinate of the stratum point in the model coordinate system.

[0091] The first position refers to the coordinate data of at least three layer points in the model coordinate system. For example, if three layer points p1, p2, and p3 are selected, the coordinates of p1 in the model coordinate system are (x1, y1), the coordinates of p2 in the model coordinate system are (x2, y2), and the coordinates of p3 in the model coordinate system are (x3, y3). The first position refers to the array composed of (x1, y1), (x2, y2), and (x3, y3).

[0092] It should be noted that three factors—scaling factor, shear factor, and offset—can be used to represent the correspondence between the initial coordinate system and the model coordinate system. For example, three stratigraphic points are selected from the geological stratigraphic data. Based on the first coordinates of these three stratigraphic points in the initial coordinate system and the second coordinates of these three stratigraphic points in the model coordinate system, the scaling factor, shear factor, and offset are calculated using the following formulas:

[0093] to_point_x=Para[0]×from_point_x+Para[1]×from_point_y+Para[2] (3)

[0094] to_point_y=Para[3]×from_point_x+Para[4]×from_point_y+Para[5] (4)

[0095] In equations (3) and (4), from_point_x and from_point_y represent the horizontal and vertical coordinates of the layer point in the initial coordinate system, and to_point_x and to_point_y represent the horizontal and vertical coordinates of the layer point in the model coordinate system. Para[0] represents the scaling factor of the horizontal axis, which determines the scaling of the layer point in the horizontal direction; Para[1] represents the shear factor of the horizontal axis, which represents the influence of the coordinate change in the vertical direction on the horizontal axis coordinate; Para[2] represents the translation amount in the horizontal direction, which represents the offset of the horizontal axis coordinate after transformation. Para[3] represents the shear factor in the vertical direction, which represents the influence of the coordinate change in the horizontal direction on the vertical axis coordinate. Para[3] represents the scaling factor of the vertical axis, which determines the scaling of the input point in the vertical direction. Para[5] represents the translation amount in the vertical direction, which represents the offset of the vertical axis coordinate after transformation.

[0096] According to formulas (3) and (4), a six-variable linear equation is listed. By solving Gaussian equations, the values ​​of the six coefficients Para[0], Para[1], Para[2], Para[3], Para[4], and Para[5] are obtained. The first horizontal axis coordinate and the first vertical axis coordinate of all layer points in the initial coordinate system are substituted into the known formulas (3) and (4) of Para[0], Para[1], Para[2], Para[3], Para[4], and Para[5] to determine the second horizontal axis coordinate and the second vertical axis coordinate of all layer points in the model coordinate system.

[0097] In this embodiment of the invention, at least three stratigraphic points are selected from geological stratigraphic data, and a first position of at least three stratigraphic points is set in the model coordinate system. Based on the second and first positions of the at least three stratigraphic points in the initial coordinate system, the correspondence between the initial coordinate system and the model coordinate system is determined. Based on the first horizontal axis coordinate, the first vertical axis coordinate, and the correspondence of the stratigraphic points in the geological stratigraphic data, the second horizontal axis coordinate and the second vertical axis coordinate of the stratigraphic points in the model coordinate system are determined, thereby improving the efficiency of determining the second horizontal axis coordinate and the second vertical axis coordinate of the stratigraphic points in the model coordinate system.

[0098] Optionally, the method further includes:

[0099] Step 31: Construct a first target range based on the distribution range of all layer points in the model coordinate system; the first target range is greater than or equal to the distribution range.

[0100] Step 32: When the first target range is larger than the distribution range, interpolate the void point according to the values ​​of the adjacent layer points of the void point; the void point exists between the first target range and the distribution range.

[0101] It should be noted that, based on the distribution range of all layer points in the model coordinate system, the first target range is constructed, including: obtaining the coordinate data of all layer points in the model coordinate system, and determining the minimum x-coordinate of the horizontal axis in the horizontal direction of all layer points in the model coordinate system. min Maximum value x max The minimum value of the vertical axis coordinate y along the vertical axis. min Maximum value y max The width of the first target range is determined by the first absolute value s1, which is the difference between the minimum and maximum values ​​of the horizontal axis coordinates; the height of the first target range is determined by the second absolute value s2, which is the difference between the minimum and maximum values ​​of the vertical axis coordinates. The width of the first target range is greater than or equal to the first absolute value, and the height of the first target range is greater than or equal to the second absolute value.

[0102] Since the distribution range of all layer points in the model coordinate system can be rectangular, circular, or irregular polygonal, the first target range is set to a rectangular range to adapt to the shape of the display area. The first target range needs to completely cover the distribution range; therefore, the first target range is greater than or equal to the distribution range. When the distribution range is irregularly shaped, there are gaps between the first target range and the distribution range. These gaps refer to areas between the first target range and the distribution range where there is no coordinate data or depth feature of the layer points.

[0103] Interpolating void points refers to setting corresponding depth features for the horizontal and vertical coordinates of the void points.

[0104] It should be noted that before interpolating the void points, the x-axis and y-axis coordinates of the void points need to be obtained. Based on the x-axis and y-axis coordinates of the void points and the layer points, the adjacent layer points corresponding to each void point are determined. Various methods can be used to represent the distance between void points and layer points, and this embodiment of the invention does not limit this. Specifically, Euclidean distance can be used to represent the distance between void points and layer points, and layer points whose Euclidean distance from the void point is less than or equal to a preset threshold are considered as adjacent layer points of the void point. For example: select a void point, obtain the Euclidean distance between the void point and all layer points, and consider layer points whose Euclidean distance from the void point is less than or equal to a preset threshold as adjacent layer points of the void point.

[0105] After determining the adjacent layer sites of the cavity, the depth features of the adjacent layer sites are obtained. Various interpolation algorithms can be used to interpolate the cavity, and this embodiment of the invention does not limit this approach. Examples include nearest neighbor interpolation and bilinear interpolation. In the process of nearest neighbor interpolation, the feature values ​​of the depth features of all adjacent layer sites can be averaged, and the average value is used as the depth feature corresponding to the cavity.

[0106] In this embodiment of the invention, a first target range is constructed based on the coordinate data of all layer points in the model coordinate system. If the first target range is larger than the distribution range, void points exist between the first target range and the distribution range. The void points are interpolated based on the depth features of adjacent layer points. By constructing the first target range, the shape of the subsequent display area is adapted. Interpolating the void points based on the depth features of adjacent layer points ensures that the depth features corresponding to the void points are close to the depth features of the adjacent layer points.

[0107] Optionally, the step of interpolating the cavity point based on the values ​​of adjacent layer points includes:

[0108] Step 41: Add all void points to the preset queue;

[0109] Step 42: If the preset queue is not empty, perform the interpolation process sequentially on each empty point in the preset queue.

[0110] Step 43: After the interpolation of the first void point is completed, remove the first void point from the preset queue and perform the interpolation process for the next void point;

[0111] Step 44: If the interpolation of the first void point is not completed, perform the interpolation process for the next void point and add the first void point to the tail of the preset queue.

[0112] Step 45: Repeatedly execute the interpolation process for each empty point in the preset queue until the preset queue is empty.

[0113] During the interpolation process for void points, a preset threshold is set. Layer points whose distance to the void point is less than or equal to the preset threshold are identified as adjacent layer points corresponding to the void point. A void point is retrieved from a preset queue, and it is checked whether there is a layer point whose distance to it is less than the preset threshold. If no layer point with a distance less than the preset threshold exists, the void point is added back to the end of the preset queue, awaiting the next interpolation process.

[0114] It should be noted that an interpolation function is defined, whose inputs are: the coordinate data of the cavity point, the coordinate data of adjacent layer points, and the depth features of the adjacent layer points; the output of the interpolation function is: the depth features of the cavity point. For example, when a cavity point is detected to have layer points whose distance from it is less than a preset threshold, these layer points are identified as the adjacent layer points corresponding to the cavity point. The depth features of the layer point closest to the cavity point among the adjacent layer points are identified as the depth features of the cavity point; or the median of the depth features of all adjacent layer points is identified as the depth features of the cavity point; or the mode of the depth features of all adjacent layer points is identified as the depth features of the cavity point; or the depth features of the cavity point are predicted by combining the overall geological undulation trend.

[0115] In this embodiment of the invention, all void points are added to a preset queue. If the preset queue is not empty, an interpolation process is performed on each void point in the preset queue sequentially. If the interpolation of the first void point is completed, the first void point is removed from the preset queue, and the interpolation process is performed on the next void point. If the interpolation of the first void point is not completed, the interpolation process is performed on the next void point, and the first void point is added to the tail of the preset queue. The interpolation process for each void point in the preset queue is executed cyclically until the preset queue is empty. Based on the first-in-first-out (FIFO) data structure characteristic of the queue, void points are added to the queue and re-entered, while adjacent layer points are directly interpolated and then dequeued, thus improving the memory pressure drawback caused by the recursive method.
