Seismic profile data visualization method and system based on adaptive mosaic

Abstract

The invention relates to a seismic section data visualization method and system based on adaptive mosaic, and the method comprises the steps: carrying out the coloring of grid vertexes corresponding to different amplitude seismic sampling points and pixels between the vertexes through different colors; calculating a sampling point most relevant to the current seismic sampling point on the next trace in a pixel shader; the relative offset of the most relevant sample points in the time direction is mapped into an inclined mode and rendered to the texture, and when the vertex index is filled, the inclined mode of adjacent sample points on the same channel is fully considered to realize self-adaptive embedding of the vertexes. The embedding mode provided by the invention can be adaptively selected according to the inclination mode of the seismic sample point, effectively solves the problem of embedding errors in the aspect of grid embedding in the three-dimensional visualization of the two-dimensional seismic section, can effectively improve the display capability of the seismic microstructure, facilitates the interpretation and analysis of seismic data, and improves the accuracy of the seismic data. The method has important significance in the fields of oil-gas exploration, geological exploration and the like.

Description

technical field [0001] The invention relates to the field of three-dimensional visualization of seismic sections, in particular to a method and system for visualization of seismic section data based on adaptive mosaic. Background technique [0002] Seismic data section visualization technology plays a key role in the interpretation of seismic exploration. The intuitive, correct, and hierarchical visualization of seismic data can greatly facilitate geological researchers to make accurate analysis of relevant data and draw correct conclusions, which is of great significance to oil and gas exploration, geological exploration and other fields. [0003] For the visualization of seismic section data, experts and scholars at home and abroad have carried out some research and made great progress. Seismic data visualization technology is mainly divided into two categories: one is two-dimensional visualization, and the other is three-dimensional visualization. Two-dimensional visuali...
