Multipoint geologic statistics method based on geologic vector information

Abstract

The invention provides a multipoint geologic statistics method based on geologic vector information. The multipoint geologic statistics method based on the geologic vector information comprises the steps that vectorization partition is conducted on a training image and a modeling area, so that multiple stable sub-blocks are obtained, stochastic simulation is conducted based on comprehensive geologic research achievements, the problem that according to a multipoint geologic statistics modeling method in the prior art, the instability of a training image and condition data is hard to overcome is solved, the reliability and rationality of a geologic model are effectively improved, and the method can be widely applied to the fields such as the geological exploration field, and the environmental monitoring field.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a multi-point geological statistical method based on geological vector information. Background technique [0002] The traditional geostatistical modeling method is represented by the two-point geostatistical method, and its core is to use the variogram to characterize the variability of regionalized variables in a certain spatial range under different distance relationships. The variation characteristics of the variables in the area to be simulated are obtained through the variogram fitting process of the conditional data, and the kriging interpolation process is applied to complete the estimation of the unknown points. Algorithms based on variogram and kriging interpolation methods can be collectively referred to as two-point geostatistical methods. [0003] The variogram can only count the variability between any two points in the three-dimensional space, but the geologic...

Problems solved by technology

This method cannot fundamentally solve the problem of instability, but also brings another problem: after each block is simulated separately, there are great differences in the splicing of the edges of each sub-block, and there are discontinuous geological bodies and splicing methods. Principles of non-composite sedimentology and other issues

Although this type of method is reasonable to a certain extent, mechanically splitting the simulation block will bring greater problems
