Abstract

The invention discloses a geological surface fitting method based on logical neighborhood; it includes constructing a three-dimensional Delaunay triangulation network, searching for seed points corresponding to points to be interpolated and performing interpolation on the points to be interpolated to construct grid point adjacency relations, and according to grid point adjacency Relational fit to geological surfaces. The present invention adopts the search method in the logic field, and by constructing a three-dimensional Delaunay triangular network, the seed points obtained by the search are distributed in all directions of the points to be interpolated, so that the interpolated data is more accurate, conforms to the trend of the space surface, and is fitted according to the interpolated data The resulting surface is more in line with the real shape of the space surface.

Description

technical field [0001] The invention belongs to the technical field of geological surface fitting, in particular to a logical neighborhood-based geological surface fitting method. Background technique [0002] Three-dimensional complex geological structure modeling is the basis of geometric ray forward modeling, Gaussian ray forward modeling and acoustic wave equation forward modeling. However, due to the complexity of the problem, 3D structural modeling has always restricted the development and application of the optimal design of the 3D observation system. [0003] 3D geological structure modeling technology is the key technology in 3D geological modeling, and it plays an increasingly important role in the process of oil and gas resource exploration. The basic process is: based on the data of geological surfaces (horizon planes and fault planes) obtained from seismic interpretation, a certain geological surface reconstruction algorithm is used to generate spatial surfaces...
