[0028] Furthermore, some solutions further include: The step of inputting the water surface data into the geological model to obtain a fusion model further includes the step of modifying the formation name to be the same as the water level layer name.

[0029] Some solutions based on the above solutions further include extracting the drilling layer points on the layer, and constructing a discrete point set of the formation nodes under the formation nodes of the modeling module by interpolation method for the discrete point set of the formation.

[0030] Some solutions further include: The step of exporting the generated discrete points of the water surface support rules to a shp file.

[0031] Some solutions based on the above solutions, the step of inputting the water surface data into the geological model to obtain a fusion model specifically includes the following steps:

[0032] In the step of the discrete point set node under the formation node of the structural modeling module executed in the 3D modeling software, import the contour data in shp format as the discrete point data of the formation surface for generating the formation surface.

[0033] If the data stored in the shp file is the water level contour, it can be used to generate the water level surface;

[0034] If the structural contour is stored in the shp file, it can be used to generate the structural formation surface.

[0035] In the preferred solution of the above embodiment, export the formation surface in the structural model to common formats such as OBJ, IFC, FBX, Geo3dml, STL.

[0036] The following details the steps in the above solution through a specific embodiment.

[0037] All steps of this embodiment are executed in the data management software (prospecting geoscience modeling software), and the specific operation steps include:

[0038] In the right-click menu of the borehole set node in the data management software, select "Download borehole data from the geological big data center".

[0039] When downloading the borehole data, select to download the water level stratification and attributes.

[0040] If the option to download the water level stratification attributes is checked, first detect whether there is a water level stratification scheme node. If not, create a water level stratification scheme node first; then download the water level stratification and attribute data and save them under the water level stratification scheme node.

[0041] Open the 3D modeling software and select the project information setting function. When the 3D modeling software needs to load borehole data from the database, it is necessary to set the project information in advance. If the option to obtain the planar working area range of the project is checked, the range information of the selected project in the database will be obtained to initialize the planar working area range of the 3D working area. The user can modify the working area range manually.

[0042] Switch to the borehole management window of the 3D modeling software. Right-click on the borehole management node and select "Load basic borehole information" in the pop-up right-click menu.

[0043] In the 3D modeling software, load the borehole water level stratification. When loading the borehole stratification, first pop up a dialog box to select the stratification scheme, and select the water level stratification to load the water level stratification data on the borehole into the well management module of the 3D modeling.

[0044] Switch to the structural modeling window, right-click on the formation set node, and select "New Formation" in the pop-up right-click menu. Select the formation node and modify the name in the property page. Note that the formation name needs to be modified to be the same as the water level stratification name.

[0045] Before generating the surface, it will be detected whether the model has been saved. If not, a dialog box for saving the model and setting the model file path will pop up.

[0046] The generated water surface supports exporting regular sampled discrete points to a shp file.

[0047] In the right-click menu of the structural model node, there is a function to export the surfaces in the structural model to common formats such as OBJ, IFC, FBX, Geo3dml, STL, etc.

[0048] In the new surface function of the data management software, open the 3D modeling software, switch to the structural modeling window, right-click on the formation set node, and select "New Formation" in the pop-up right-click menu.

[0049] Select the formation node and modify the name in the property page. Note that the formation name needs to be modified to be the same as the water level stratification name.

[0050] In the right-click menu of the discrete point set node under the formation node in the structural modeling module of the 3D modeling software, shp format contour data can be imported as the discrete point data of the surface for generating the surface.

[0051] If the data stored in the shp file is the water level contour, it can be used to generate the water level surface;

[0052] If the shp file stores structural contours, it can be used to generate structural surfaces.

[0053] It is necessary to select the corresponding attribute name of the elevation attribute in the file.

[0054] After extracting the work area range, you can also view and modify the work area range in the property page of the structural model node. Note that when extracting the work area range according to the actual data, it is the smallest range containing the data. The longitudinal z-value range usually needs to be modified and set slightly larger to prevent the situation where the surface cannot be generated or is not fully generated due to exceeding the work area z-range.

[0055] Select the "Generate Surface" function in the right-click menu of the formation node in the 3D modeling software.

[0056] Before generating the surface grid, it will be detected whether the current model has a modeling working directory, that is, whether it has been saved. If the current model has not been saved, a file directory selection window for saving the model will pop up. The user selects the model storage directory, sets the model file name, and then clicks "Save".

[0057] Set the generation method of the layer before generating the layer, such as the inverse distance weighting method, to generate visual effects such as Figure 3 of the water level surface.

[0058] Right-click on the structural model node, select Export STL in the pop-up right-click menu, and then the following Export STL Export Path Settings dialog box will pop up; select a file directory for storing the exported file, and click the "OK" button, then the file will be saved to this location.

[0059] Right-click on the structural model node and select Export OBJ in the pop-up right-click menu.

[0060] Select a file directory for storing the exported file, and click the "OK" button, then the file will be saved to this location.

[0061] Right-click on the structural model node, select Export IFC in the pop-up right-click menu, and then the following Export IFC Parameter Settings dialog box will pop up:

[0062] Export Path: Select a file directory location for storing the exported file;

[0063] Select IFC Version: Supports exporting two versions, IFC2x3 and IFC4.

[0064] Project Base Point Settings:

[0065] Set the x, y, and z coordinates of the base point, which is default to the lower left corner point of the working area of the current structural model;

[0066] Set the rotation angle of the y-axis of the project coordinate system relative to true north, which is default to 0 degrees.

[0067] Export Formation Surfaces: If checked, the surfaces of the formations currently checked and displayed in the structural model will be exported to the IFC file;

[0068] Export Formation Bodies: If checked, the formation bodies of the formations currently checked in the structural model will be exported to the IFC file.

[0069] Separate Export: If not checked, all objects to be exported will be exported to the same IFC file. If checked, an IFC file will be exported separately for each object.

[0070] The effect of the fused water level surface is as Figure 3 .
