Problems solved by technology

[0005] However, such techniques all indirectly infer the distribution of fracture phylogenetic zones, and can only qualitatively predict the relative development of fractures but cannot predict the orientation and density of fractures.

Abstract

Disclosed is a crack fused data volume obtaining method. The method may comprises that a post-stack optimal data volume is obtained on the basis of a post-stack seismic data volume; a linear crack inthe post-stack optimal data volume is reinforced linearly in a graded way to obtain post-stack crack data; a pre-stack crack is predicted on the basis of a pre-stack seismic data volume; the predicated pre-stack crack is compared with the post-stack optimal data volume and a logging data volume to obtain a pre-stack optimal data volume and further pre-stack crack data; and the post-stack crack data and the pre-stack crack data are normalized to obtain a crack fused data volume. Optimal improved fusion is carried out aimed at symptoms of cracks in different scales, the different attribute volumes are represented as an integrated symptom volume in a fused way, and the whole crack system with different scales of cracks is represented in a full-scale way.

Description

technical field [0001] The invention relates to the technical field of oil and gas geophysics, and more specifically, to a method for obtaining fracture fusion data volumes. Background technique [0002] As part of the effective storage space and the main seepage channel of oil and gas in the reservoir, fractures control the occurrence and productivity of oil and gas. Favorable fracture development zones often indicate the existence of high oil and gas production areas. In tight sandstone and volcanic rock reservoirs, it is more There is a theory that "seamless reservoirs will not form", so it can be seen that the fracture system plays a vital role in the enrichment and accumulation of oil and gas in fractured reservoirs. [0003] As early as the 1970s, foreign countries began to use seismic methods to detect fractured oil and gas reservoirs, and experienced several stages of development, including shear wave exploration, multi-wave and multi-component exploration, and longi...
