Abstract

The invention discloses a method for establishing a speed depth model based on gather data. Compared with a speed depth model established by other methods, the speed depth model established by the method is clearer, more accurate and clearer; and compared with a traditional speed depth model establishing method, the disclosed method has the advantages that modeling work can be accurately carried out on the speed depth model of the high and steep area of the mountainous area. Subsequent pre-stack depth migration processing is carried out by using the speed and depth model obtained by the method, so that a seismic data volume reflecting correct underground geological conditions is obtained.

Description

technical field [0001] The invention relates to the field of petroleum geophysical exploration, in particular to a method for establishing a velocity-depth model based on gather data. Background technique [0002] Seismic exploration is a geophysical exploration method that uses the difference in elasticity and density of underground media to infer the nature and shape of underground rock formations by observing and analyzing the response of the earth to artificially excited seismic waves. Seismic exploration is an important means of surveying oil and natural gas resources before drilling and is widely used. Seismic exploration is of great significance to guide drilling. [0003] In oil and gas exploration in the Sichuan Basin of China, the imaging requirements for high and steep structures are quite urgent. Relevant oil and gas exploration shows that the geological structure encountered by drilling is quite different from the structure in seismic data. Originally, the dr...
