Abstract

The invention provides a seismic data acquisition footprint processing method and device. The method comprises the following steps: carrying out pre-stack preprocessing on seismic data to obtain post-stack seismic data; carrying out vacancy filling processing on the post-stack seismic data to obtain post-stack seismic data after vacancy filling; rotating the post-stack seismic data after the vacancy filling to obtain rotated post-stack seismic data; performing acquisition footprint pressing on each piece of slice data of the rotated post-stack seismic data to obtain suppressed post-stack seismic data; performing reverse rotation on the suppressed post-stack seismic data to obtain reversely rotated post-stack seismic data; and performing recovery processing on the reversely rotated post-stack seismic data to obtain recovered post-stack seismic data. The device is used for executing the method. According to the seismic data acquisition footprint processing method and device provided by the embodiment of the invention, the signal-to-noise ratio and the resolution of the seismic data are improved.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a processing method and device for collecting footprints of seismic data. Background technique [0002] Currently, oil and gas exploration is developing in both breadth and depth. The goal of the former is to discover oil and gas fields in new prospective exploration fields; the latter requires finding those oil and gas reservoirs with large burial depth and high complexity, and at the same time requires solving problems such as fine structure and fine description of reservoir parameters. With the continuous deepening of exploration of lithologic oil and gas reservoirs and subtle oil and gas reservoirs, the geological target has also shifted from the original structural oil and gas search to lithological oil and gas search. To solve the problem of fine description of oil and gas reservoirs and reservoir parameters, it is necessary to involve Imaging data signal-to-no...
