Three-dimensional geological analysis prediction model construction method

Abstract

The invention discloses a three-dimensional geological analysis prediction model construction method. The method comprises the following steps: S1, acquiring drilling data of a three-dimensional geological model construction area; S2, triangularizing and grouping the drilling data to form an initial triangulation network; S3, performing pinch-out processing on the initial triangulation network according to a pinch-out processing rule to generate a pinch-out processing triangulation network; S4, performing interpolation encryption on the pinch-out processing triangulation network to generate anadaptive interpolation encryption processing triangulation network; S5, performing staggered stacking on the adaptive interpolation encryption processing triangulation network to form a stratum, obtaining a stratum set, and generating a three-dimensional geological analysis prediction model; and S6, performing precision verification on the three-dimensional geological analysis prediction model, if the precision is unqualified, skipping to the step S1, and otherwise, taking the three-dimensional geological analysis prediction model generated in the step S5 as a final model. The pinch-out processing and the interpolation encryption processing are adopted, so that the constructed model can fit a space entity to the greatest extent, and the precision of the model is improved.

Description

technical field [0001] The invention relates to the technical field of geological three-dimensional model construction, in particular to a method for constructing a three-dimensional geological analysis and prediction model. Background technique [0002] At present, the acquisition cost of geological survey data in electric power, municipal and other projects is high, and due to the limitation of geological survey costs, it is usually difficult to obtain all the geological survey data of the actual project. The construction cost is too high, and at the same time, there is a big difference between the constructed 3D geological model and the real geology. In addition, the method of "one project, one geological survey" is usually adopted, and historical geological survey data has accumulated a lot, and there is no way to reuse it.

Problems solved by technology

[0003] The present invention mainly solves the technical problem that the three-dimensional geological model constructed by the original three-dimensional geological model construction method is quite different from the real geology; it provides a three-dimensional geological analysis and prediction model construction method, which triangulates the drilling data into groups, and The discrete points in the borehole data are associated to improve the effective utilization of the borehole data. The pinch-out processing and interpolation encryption processing can make the constructed 3D geological model fit the spatial entity to the greatest extent, greatly improving the model quality. the accuracy of
