The invention provides a three-dimensional geologic model modeling method and device and a readable storage medium, and the method comprises the steps: obtaining a plurality of drill holes in a working area, wherein each of the plurality of drill holes comprises a plurality of stratums; carrying out primary coding on a plurality of stratums of a drilled hole based on an original standard stratum table to generate primary stratum codes; judging whether the drill hole is reversed or not according to the primary stratum code, and if the drill hole is reversed, carrying out secondary coding on the primary stratum code to generate a secondary stratum code; acquiring the drilling data, the stratum elevation and the geological background of the plurality of drilling holes, and establishing the topological relation of the plurality of drilling holes according to the drilling data, the stratum elevation and the geological background; and establishing a three-dimensional geologic model according to the topological relation among the plurality of drill holes and the secondary stratigraphic codes. According to the invention, the reliability of the established three-dimensional geologic model is improved.
Description
technical field [0001] The invention relates to the technical field of geological modeling, in particular to a three-dimensional geological model modeling method, device and readable storage medium. Background technique [0002] 3D geological modeling has always been a technical hotspot and difficult issue in the research of engineering, geology, and mining industries. Restoring the underground geological structure and petrophysical parameters through limited geological data plays a very important role in engineering geological analysis, oil and gas and mineral exploration and development. Due to the diversity and multiple solutions of geological data and the limited means of data acquisition, 3D geological modeling is difficult and the implementation process is complicated. Among them, 3D geological modeling by coding strata is a common method. The three-dimensional geological model constructed in this way can relatively accurately reflect complex geological phenomena in ...
