Embodiment 1
[0042] In this embodiment, there are n strata in total from 1 to n according to the order of new and old strata, wherein No. 1 stratum is the latest and No. n is the oldest. strata within the map area. This embodiment provides a method for generating an isopach map of a certain stratum (target stratum X) demarcating the stratum boundary of a certain region.
[0043] refer to figure 1 As shown, the method for automatically generating the stratum contour map described in this embodiment includes the following steps:
[0044] S10. Obtain the drilling information of all holes in the mapping area. The drilling information includes point information and layer information, wherein the point information is the spatial coordinate of the drill hole, and the layer information includes stratum age, lithology, and buried depth. Wait.
[0045] Specifically, according to the stratum information of the borehole, all the boreholes are divided into three categories: holes with target stratum...
Embodiment 2
[0076] An embodiment of the present invention provides a device for automatically generating stratum contour maps, including:
[0077] The information acquisition module is used to obtain the drilling information of the target layer hole and the non-target layer hole in the mapping area. The drilling information includes point information and layer information; the target layer is the stratum boundary that needs to be divided currently strata within the mapped area;
[0078] The first calculation module is used to calculate the thickness value T of the target layer with holes in the target layer 目+ , and calculate the average thickness of the target layer, denoted as "T 1 ";
[0079] The first interpolation module is used to use the point information of the hole in the target layer and its corresponding thickness value T 目+ Take point data as discrete data, interpolate it to generate thickness DEM, denoted as DEM_T 目+ ;
[0080] The second calculation module is used to ex...
Embodiment 3
[0084] An embodiment of the present invention provides a terminal device, including a processor and a memory, the memory is used to store a computer program; the processor is used to execute the computer program and realize the embodiment of the present invention when executing the computer program 1 provides a method for automatically generating stratigraphic contour maps.
[0085] It should be understood that the processor may be a central processing unit (Central Processing Unit, CPU), and the processor may also be other general-purpose processors, digital signal processors (Digital Signal Processor, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), Field-Programmable Gate Array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. Wherein, the general-purpose processor may be a microprocessor or the processor may be any convention...
