Abstract

The invention discloses a seismic data processing method and system, and belongs to the field of seismic data processing. The method comprises the steps that a CPU determines the imaging aperture corresponding to pre-stack seismic data, target seismic data corresponding to an imaging line corresponding to the pre-stack seismic data are determined according to the imaging aperture, the target seismic data corresponding to the imaging line are transmitted to a GPU, and the GPU performs high-frequency energy compensation on the target seismic data corresponding to the imaging line so that imaging of the pre-stack seismic data is determined. The problem of low efficiency of data processing can be solved and the efficiency of data processing can be enhanced so that the seismic data processing method and system are used for processing of the pre-stack seismic data.

Description

technical field [0001] The invention relates to the field of seismic data processing, in particular to a seismic data processing method and system. 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 strata by observing and analyzing the response of the earth to artificially excited seismic waves. [0003] In related technologies, acquisition equipment can be used to collect seismic waves to obtain pre-stack seismic data, and the pre-stack seismic data can be processed to determine the nature and shape of strata, and then determine the distribution of strata. For example, when processing the pre-stack seismic data, the central processing unit (English: Central Processing Unit; CPU for short) of the computer may be controlled to process the pre-stack seismic data using the pre-stack time migration method to determine the pre-stack seismic ...
