[0025] Please refer to Figure 1 , Figure 1 The illustration shows a flowchart of a contour line drawing method according to an embodiment of this application. This embodiment provides a contour line drawing method applied to a map page in a browser, the contour line drawing method comprising the following steps: Step 210: Invoke the map editing plugin to obtain data source and parameter information; In this embodiment, the map editing plugins mentioned above include Leaflet, OpenLayers, etc., which enable the function of editing drag-and-drop layers on the page. Among them, Leaflet.pm (Leaflet-Plugin for Draw / Edit / TransformGeometries) is a powerful plugin for Leaflet.js, which focuses on adding functions for drawing, editing, and transforming geometry on maps. This plugin greatly enhances Leaflet's map editing capabilities, allowing users to easily create and modify geospatial data on maps. For ease of explanation, this embodiment mainly uses Leaflet.pm as an example for map editing plugin. Open the map page in the browser and call the map editing plugin. There are two ways to obtain data: one is to obtain the data source by copying and pasting Excel data of well feature values, and then generate a contour map; the other is to obtain the data source by selecting well feature values ​​in an online data table, and then draw the contour map. The above parameter information refers to the parameters used to draw contour lines, including well parameters, gradient, gradient color, etc. The above data source includes a list of well names, feature values, etc.

[0026] In some embodiments, obtaining parameter information includes the following steps: First, obtain the well parameters, contour range, and contour interval; In this embodiment, well parameters include information such as well location, model, and weights, and contour ranges include maximum and minimum contour values. The contour range and contour intervals can be user-defined.

[0027] Then, gradient information is calculated based on the contour range and the contour interval; In this embodiment, the gradient information includes the number of gradients and the gradient values ​​of each contour line. Each gradient value is: minimum contour value + gradient index * contour interval. First, the difference between the maximum and minimum contour values ​​is calculated, and then the difference is divided by the contour interval to obtain the number of gradients, thereby obtaining the gradient index of each gradient.

[0028] Then, based on the gradient information, the contour line color information is obtained; In this embodiment, the contour line color information includes the color corresponding to each gradient. Each gradient has a color selector, and the user can customize the color to obtain the color corresponding to each gradient, so as to distinguish the gradients later.

[0029] Finally, based on the well parameters, the gradient information, and the contour line color information, the parameter information is obtained.

[0030] In this embodiment, the parameter information includes well parameters, gradient information, and contour line color information.

[0031] In practice, the relevant information can be obtained by calling a dialog box, for example: please refer to Figure 3 , Figure 3 The diagram illustrates a contour line drawing interface according to an embodiment of this application.

[0032] 1. After bringing up the contour configuration dialog box, paste the data source (well name list and feature values).

[0033] 2. Click the Parameters tab to select the interval, maximum value, and minimum value data, then click Next to switch to the Contour Configuration tab.

[0034] 3. After editing the gradient color in the contour tab, click the generate button.

[0035] By acquiring well parameters, contour range, and contour interval; calculating gradient information based on the contour range and contour interval; and acquiring contour color information based on the gradient information, parameter information can be accurately obtained, facilitating user operation.

[0036] Step 220: Based on the parameter information and the data source, generate an initial contour map on the map page; The step of generating an initial contour map on the map page based on the parameter information and the data source includes: First, spatial correlation modeling of the data source is performed using the Kriging interpolation method to obtain isosurface data; In this embodiment, the kriging-contour library can be selected to process the source data and output it as geoJSON format. The kriging-contour library is used to generate Kriging interpolation contour lines. This library focuses on generating corresponding contour maps based on Kriging interpolation to visually display the spatial distribution characteristics of the data. The above-mentioned estimation of the values ​​of unknown points using the ordinary Kriging interpolation algorithm by modeling spatial correlation specifically includes the following steps: 1) Data collection and preprocessing a) Collect spatially distributed data points, namely: well coordinates and well parameter attribute values.

[0037] b) Preprocess the data to remove outliers and fill in missing values.

[0038] 2) Semivariogram analysis a) Calculate the semivariogram values ​​between known points to quantify their spatial correlation.

[0039] b) Select a suitable semivariogram model (here, an exponential model is used) and fit the model parameters.

[0040] 3) Construct the weight matrix a) Calculate the spatial correlation between unknown points and known points based on the semi-variogram model.

[0041] b) Construct a weight matrix that reflects the contribution of known points to the interpolation results of unknown points.

[0042] 4) Interpolation calculation a) Calculate the interpolation results for unknown points using the weight matrix and the attribute values ​​(well parameter values) of known points.

[0043] b) The interpolation result is usually a weighted average, with the weights determined by the semi-variogram function.

[0044] 5) Results Verification and Evaluation a) Use methods such as cross-validation to evaluate the accuracy of the interpolation results.

[0045] b) Compare the interpolation results with the actual situation to conduct error analysis and accuracy evaluation.

[0046] In some embodiments, the step of using the Kriging interpolation method to model the spatial correlation of the data source to obtain isosurface data includes the following steps: The first step is to organize the data from the data source according to the preset first data format to obtain the first format data; In this embodiment, the aforementioned preset first data format refers to: value, longitude, and latitude. The data source is organized according to the first data format into data containing feature values, longitude, and latitude. This organization may involve finding the longitude and latitude corresponding to the feature values ​​separately.

[0047] The second step is to organize the first format data according to the preset second data format to obtain the second format data; In this embodiment, the aforementioned preset second data format refers to the geoJSON format. The geoJSON format is an open standard format for representing geospatial data, capable of describing geographic features such as points, lines, and polygons. The data can be formatted into geoJSON using existing technologies, and will not be elaborated upon further here.

[0048] In some embodiments, the step of processing the first format data according to a preset second data format to obtain the second format data includes the following steps: First, based on the preset geographic location information, the first format data is filtered to obtain location data; In this embodiment, the preset geographical location information can be latitude and longitude information, such as: domestic latitude and longitude (72.004 < longitude < 137.8347) (0.8293 < latitude < 55.8271). The above filtering refers to filtering out data whose latitude and longitude meet the preset geographical location information to obtain location data.

[0049] Then, the location data is processed according to the preset second data format to obtain second format data.

[0050] In this embodiment, after obtaining the location data, the data is converted into a second data format to obtain second format data. Specifically, this can be done by iterating through the first format data, extracting the logitude (longitude) and latitude (latitude) field values ​​of each item in the data to form an array called coordinates, then iterating through coordinates, filtering out domestic longitude and latitude (72.004 < longitude < 137.8347) (0.8293 < latitude < 55.8271), and then putting the location data into the coordinates property of gometry in boundaries (geoJSON format). At this point, a standard geoJSON format object is completed.

[0051] In some embodiments, the step of processing the location data according to a preset second data format to obtain second format data includes: First, the location data is converted according to a preset second data format to obtain second initial format data; Then, the second initial format data is sorted according to the preset sorting rules to obtain the second format data.

[0052] In this embodiment, the values ​​of `boundaries.features` must be positive and in ascending order; otherwise, the libraries referenced by the `kriging-contour` library will not be able to return the correct values. Therefore, the `boundaries` object needs further processing to ensure that the values ​​are positive and ordered. That is, the second initial format data needs to be sorted by positive and ascending values. The preset sorting rule refers to positive and ascending value sorting. This sorting can be achieved by calling the `sort` method on the `boundaries.feature` array, comparing adjacent values, placing the smaller one first and the larger one last.

[0053] The third step involves using the Kriging interpolation method to model the spatial correlation of the second format data, thereby obtaining isosurface data.

[0054] In this embodiment, the `kriging.getVectorContour` method is used to generate vector data of isosurfaces, i.e., isosurface data, based on the well's location, model, and weights. Specifically, the `kriging.getVectorContour` function can be used, represented as: `kriging.getVectorContour(dataSet, value, param, level)`, where `dataSet` is a GeoJSON format Feature Collection dataset, i.e., second-format data; `value` is the name of the weighted field; and `param` is: `model`: the interpolation model (here, an exponential model is used), `sigma2`: variance, and `level` is the weighted isosurface classification data. The `kriging.getVectorContour` method mainly uses the ordinary Kriging interpolation algorithm to estimate the values ​​of unknown points by modeling spatial correlation.

[0055] Then, based on the parameter information and the isosurface data, an initial contour map is generated on the map page.

[0056] The step of generating an initial contour map on the map page based on the parameter information and the isosurface data includes the following steps: The first step is to calculate the cache area for each point in the isosurface data to obtain the cache elements for each point; In this embodiment, the vector data of the isosurface can be a buffer that calculates each point in the isosurface data using the turf.buffer function of the turf library.

[0057] The second step is to integrate the cached elements of each point to obtain the clipping region data; In this embodiment, the `turf.featureCollection` method is used to convert the data to a feature collection format in GeoJSON to obtain the final clipped region. The `turf.featureCollection` method then integrates all the previously calculated and buffered features into a single `FeatureCollection` conforming to the GeoJSON specification. This collection represents the final clipped region data.

[0058] The third step is to generate an initial contour map on the map page based on the parameter information, the cropping area data, and the isosurface data.

[0059] In this embodiment, geoJSON data format is used in Leaflet to mark each point, draw the region, and finally plot it on a map to obtain an initial contour map. Specifically, the previously generated GeoJSON data representing the clipping region is added to the Leaflet map. Custom style settings can be applied to different geometric types (points, polygons, etc.) to ensure a clear and aesthetically pleasing display on the map. Figure 2 As shown, Figure 2 A contour map according to an embodiment of this application is illustrated schematically.

[0060] Step 230: Obtain layer operation instructions, and based on the layer operation instructions, edit the layers in the contour map to obtain a new contour map.

[0061] In this embodiment, the editing can be done by clicking on any layer of the contour map to display the control points of that gradient range layer, and then dragging to modify the generated layer style. Alternatively, it can be done by clicking on two adjacent layers, dragging two control points from one layer to the other layer to make them intersect, and then clicking the merge button to merge the layers.

[0062] In the above implementation process, a map editing plugin is invoked on the map page in the browser to obtain data source and parameter information; based on the parameter information and the data source, an initial contour map is generated on the map page; layer operation instructions are obtained, and based on the layer operation instructions, the layers in the contour map are edited to obtain a new contour map, thus realizing the function of online contour map generation. The map editing plugin allows for editing, dragging, cutting, and deleting layers. Compared to the slow map generation and complex operation of professional desktop software, it provides a lightweight web-based drawing display and flexible configuration, offering users a faster and more convenient operating experience. This meets the data mapping needs of the old oilfield potential tapping and evaluation production process and provides graphical numerical references for the evaluation of old oilfields.

[0063] Based on the fundamental capabilities of the map component library Leaflet.js, the function of generating contour maps online is implemented through libraries such as kriging-contour.js, Turf.js, leaflet.pm.js, and leaflet-polylinedecorator.js.

[0064] In some embodiments, the method further includes: creating a legend control on the map page based on the new contour map.

[0065] In this embodiment, a control object can be initialized using the L.control() method provided by Leaflet, and then the onAdd function can be defined to customize the control's content and behavior when added to the map. Creating a legend control can improve map readability and facilitate user interaction.
