Method and device for double-layer flood fill seismic horizon space automatic tracking

Abstract

The embodiment of the invention provides a method and a device for double-layer flood fill seismic horizon space automatic tracking. The method comprises the following steps: dividing a seismic work area into a plurality of blocks according to the size of the seismic work area; taking the common mid-points of horizon values greater than zero as seed points, and determining the block to which each seed point belongs according to the coordinate value of the seed point; and for each block containing seed points, carrying out automatic seismic horizon space tracking on the common mid-points around each seed point of the block by taking the seed point as the center, and determining the blocks containing seed points around the block by taking the block as the center. The technical problem that computer memory consumption is high during automatic space tracking of a three-dimensional seismic horizon in the prior art is solved. Thus, on the premise of ensuring the accuracy of seismic horizon space automatic tracking, the computer memory consumption in the process of automatic tracking of super-large-scale seismic work area horizon is reduced, and the efficiency of seismic horizon space automatic tracking is improved.

Description

technical field [0001] The invention relates to the technical field of seismic data processing, in particular to a method and device for automatic tracking of seismic horizon space filled by double-layer floods. Background technique [0002] In seismic exploration, it is an important part of seismic data analysis to extract stratum structure information from seismic data according to seismic reflection characteristics. Structural interpretation of seismic data, especially horizon interpretation, is a very time-consuming and laborious work. In the past few decades, this work often accounted for 50%-80% of the entire seismic data interpretation and analysis work. Therefore, the automatic identification and interpretation of horizons based on computer intelligence technology (abbreviated as automatic seismic horizon tracking or horizon tracking) is very important. [0003] Automatic tracking of seismic horizon space is one of the most critical technologies in modern seismic da...
