Rapidly progressive three-dimensional geologic modeling method

Abstract

The invention discloses a rapidly progressive three-dimensional geologic modeling method based on drill holes. The method comprises the following steps: generating a two-dimensional exploration cross-section drill hole arrangement diagram according to one-dimensional drill hole data, and directly performing multidirectional cross-section stratum line connecting and cooperative processing, and is characterized by comprising the following detailed steps: according to the actual position, spreading the cross sections of the drill holes in the multiple directions in a three-dimensional space, using an interpolation algorithm to perform cross section interpolation on the stratum lines with the same attribute, generating a three-dimensional stratum surface, and at last using a top-bottom tessellation algorithm to construct the whole three-dimensional geologic body model. According to the rapidly progressive three-dimensional geologic modeling method disclosed by the invention, the stratum lines and the plane position are more accurate by stratum line connection and cooperative processing, and coordinate correction in the three-dimensional space; the speed and the efficiency for the three-dimensional geologic modeling can be obviously improved by utilizing the interpolation algorithm to generate the stratum surface; according to the model modeled by the method, the more the drill holes and the exploration line data are, the finer the division of the stratum is, and the higher the fineness of the established three-dimensional geologic model is; the method can be popularized and applied to multiple professional three-dimensional geologic modeling software.
