[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some, rather than all, of the embodiments of the present disclosure. Usually, the components of the embodiments of the present disclosure described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the present disclosure to be protected, but only represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present disclosure.

[0049] It should be noted that similar reference numerals and letters indicate similar items in the following accompanying drawings. Therefore, once an item is defined in one accompanying drawing, it does not need to be further defined and explained in subsequent accompanying drawings.

[0050] As used herein, the term "and / or" merely describes an associated relationship and indicates that there can be three relationships. For example, A and / or B can represent three cases: A exists alone, both A and B exist simultaneously, and B exists alone. Additionally, the term "at least one" as used herein means any one of a plurality or any combination of at least two of a plurality. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0051] Through research, it has been found that existing contour software cannot freely control the direction of the generated contours and the source direction. Using the method of adding virtual wells and constraint lines also fails to achieve the required effect. Areas that should be connected often remain unconnected, forming circular areas. Therefore, there are still problems with the poor generation effect of the contour map.

[0052] Based on the above research, the present disclosure provides a method, apparatus, and electronic device for generating an oilfield contour map. By obtaining basic oilfield data, a basic oilfield plan view is drawn according to the well attribute data included in the basic oilfield data. The data to be plotted included in the basic oilfield data is determined, and the inverse distance weighted difference algorithm is used to interpolate and construct a target value grid for the data to be plotted, and a basic contour map is generated according to the target value grid. A brush tool configured with preset contour anisotropy parameters is provided, and in response to a user's movement operation of the brush tool on the basic contour map, according to the preset contour anisotropy parameters, the grid value at the target value grid corresponding to the position where the brush tool is located is updated. A target contour map is generated according to the updated target value grid. Multiple parameter sources can be plotted within a single contour range, improving the generation effect of the contour map.

[0053] To facilitate the understanding of this embodiment, first, a method for generating an oilfield contour map disclosed in the embodiments of the present disclosure will be introduced in detail. The execution subject of the method for generating an oilfield contour map provided in the embodiments of the present disclosure is generally a computer device with certain computing capabilities. Such a computer device includes, for example: a terminal device or a server or other processing devices. The terminal device can be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementation manners, the method for generating an oilfield contour map can be implemented by a processor calling computer-readable instructions stored in a memory.

[0054] See Figure 1As shown in the figure, it is a flowchart of a method for generating an oilfield isogram provided by an embodiment of the present disclosure. The method includes steps S101 to S104, where:

[0055] S101. Obtain basic oilfield data, and draw a basic oilfield plan view according to the well attribute data included in the basic oilfield data.

[0056] In a specific implementation, obtain the basic oilfield data within the current oilfield range, and draw a basic oilfield plan view corresponding to the current oilfield range according to the well attribute data included in the oilfield basic oilfield data and the drawing scale selected by the user.

[0057] Here, the basic oilfield data may include the data to be plotted for which the user needs to correspondingly display continuous and gradually changing quantitative characteristics in the isogram and well attribute data.

[0058] Among them, the well attribute data may include: well point data, work area data, attribute body data, geological data, etc.

[0059] As a possible implementation manner, step S101 may be implemented through the following steps 1 to 3:

[0060] Step 1. Determine the well attribute data included in the basic oilfield data.

[0061] Step 2. Organize the well attribute data into target format data in GeoJson format.

[0062] Step 3. Draw a basic oilfield plan view marked with the well attribute data according to the target format data.

[0063] In a specific implementation, organize the basic oilfield data in GeoJson format, and import the standard data into the software system by means of import or API loading. The imported data includes work area boundaries, well point coordinates, attribute body data, etc. After the data loading is completed, draw a basic plan view, draw each well point on the map according to the selected drawing scale, and mark each attribute body beside the well.

[0064] Here, GeoJson is a format for encoding various geographical data structures, a geospatial information data exchange format based on JavaScript Object Notation (JSON for short). A GeoJson object can represent geometries, features, or feature collections. GeoJson supports the following geometric types: point, line, polygon, multi-point, multi-line, multi-polygon, and geometry collection. A feature in GeoJson contains a geometric object and other attributes, and a feature collection represents a series of features.

[0065] S102. Determine the data to be plotted included in the basic oilfield data, use the inverse distance weighted difference algorithm to interpolate the data to be plotted to construct a target value grid, and generate a basic contour map according to the target value grid.

[0066] In a specific implementation, for the data to be plotted included in the basic oilfield data, and according to the data values corresponding to the data to be plotted, the inverse distance weighted interpolation method is used to construct a network, and a target value network with a grid structure is constructed. After the target value network is constructed, the grid points with the same data value in the target value network can be traced to generate a basic contour map.

[0067] Specifically, the method for constructing the target value grid can be realized through the following steps 1 - 5:

[0068] Step 1. Determine the sampling point positions corresponding to the data to be plotted, and select the target position to be interpolated.

[0069] Step 2. For each of the sampling point positions, determine the distance index value between the target position to be interpolated and the sampling point position.

[0070] Step 3. According to the distance index value, determine the target weight corresponding to each of the sampling point positions.

[0071] Step 4. Perform a weighted average operation on the data values to be plotted corresponding to each of the sampling point positions according to the target weight to determine the target interpolation result.

[0072] Step 5. According to the target interpolation result and the target position to be interpolated, and the data values to be plotted and the sampling point positions, construct the target value grid.

[0073] In a specific implementation, first determine the position to be interpolated and the known sample point positions. According to the Euclidean distance or other distance indexes between the position to be interpolated and the known sample points, calculate the weight of each sample point, and perform a weighted average on the function values of each sample point using the weight to obtain the interpolation result. At this point, the value construction of the grid structure is completed, and the operation of generating the contour map can be performed.

[0074] Furthermore, for the generated basic contour map, parameter settings for the provenance direction and anisotropy can also be provided based on the actual situation to intervene in the generation of the contour lines; the generated contour lines meet the needs of the initial mapping.

[0075] S103. Provide a brush tool configured with preset contour line anisotropy parameters. In response to the user's movement operation of the brush tool on the basic contour map, update the grid value at the target value grid corresponding to the position where the brush tool is located according to the preset contour line anisotropy parameters.

[0076] In a specific implementation, a brush tool is provided. The brush is configured with preset contour anisotropy parameters for data adjustment of the underlying target value grid in the basic contour map. The grid values in the area passed by the brush are visually modified according to the modification intensity and modification range configured for the brush. After the modification, the corresponding grid values actually change.

[0077] Here, the responsive user movement operation can be a mouse movement event. According to the movement route and residence time of the brush in the value grid, and in combination with the modification intensity pre-configured for the brush, the value modification control of the selected grid values is controlled.

[0078] Among them, the preset contour anisotropy parameters include: a contour direction parameter and a contour angle parameter; the direction weight corresponding to the contour direction parameter and the angle weight corresponding to the contour angle parameter.

[0079] Optionally, the input parameter format of the brush tool can be the brush attribute BrushAttr: {Strength: 8, Alpha: 15} original grid [[x: 0, y: 0, v: 0], [x: 0, y: 0, v: 0], [x: 0, y: 0, v: 0]], and the output parameter format can be the result value: [[x: 0, y: 0, v: 0], [x: 0, y: 0, v: 0], [x: 0, y: 0, v: 0]].

[0080] Among them, xy are the horizontal and vertical coordinates of the well equipment coordinates, and v is the brush attribute value.

[0081] As a possible implementation, see Figure 2 As shown, it is a flowchart of a grid value update method provided by an embodiment of the present disclosure. The method includes steps S1031 to S1034:

[0082] S1031. After the brush tool is started, initialize the initial position corresponding to the brush tool.

[0083] S1032. Determine the movement position corresponding to the brush tool according to the movement operation.

[0084] S1033. Determine the target grid area covered by the brush tool in the target value grid according to the movement position and the adjustment range corresponding to the brush tool.

[0085] S1034. Adjust the grid values corresponding to the target grid area according to the preset contour anisotropy parameters.

[0086] As a possible implementation, after adjusting the grid values corresponding to the target grid area to access the preset filling attribute database, it is also possible to determine the target filling attribute corresponding to each grid value in the updated target value grid according to the correspondence between the grid values and the filling attributes stored in the filling attribute database; and fill the target image style at the corresponding position of the grid value in the target isogram according to the target image style corresponding to the target filling attribute.

[0087] Here, after the grid values are modified, the grid can be refilled according to the filling attributes of the grid values. The filling attributes can be the image styles preset for different ranges enclosed by the isograms in the isogram to distinguish different isograms. For example, for different ranges enclosed by the isograms, different range filling color styles are preset according to the data values of the isograms.

[0088] Specifically, a brush tool can be used to correct the parameter values of the triangular grid, draw the color of the triangular grid in real time, and add traced isograms after refreshing.

[0089] Exemplarily, the brush tool can have a mode setting parameter, a brush size parameter, an intervention range value parameter, and a concentration parameter. Among them, the mode setting parameter includes an enhancement mode, a weakening mode, and a smoothing mode; the brush size is in screen pixels; the minimum value of the intervention range value is 0, and the maximum value can be custom-set according to actual needs; the concentration parameter ranges from 1% to 100%.

[0090] Here, when the brush tool is started, a circular brush tool icon will appear in the work area. When moving the brush tool in the area to be modified, the grid values of the grid area covered by the brush tool are modified according to the mode setting parameter and the intervention range value parameter set by the brush. During the modification process, the modification amplitude of the grid values can be determined through the set concentration parameter, thereby achieving effects such as connection, shortening, smoothing, and range change of the isograms.

[0091] S104. Generate a target isogram according to the updated target value grid.

[0092] In a specific implementation, each of the grid values in the target value grid is traversed, and the grid values with the same numerical value are screened; the grid values with the same numerical value are connected. After the grid is refilled according to the filling attributes of the grid values and the isogram tracing is performed again according to the data, the isogram desired by the user can be obtained.

Multiple parameter sources can be drawn within a contour range, improving the effect of generating the contour map.
