Abstract

The invention discloses a method for processing pre-stack wide-line seismic data. The method includes the following steps: step 1, acquiring pre-stack wide-line seismic data; The data were merged into prestack single-line seismic data. Compared with the prior art, using the processing method of the present invention to process the pre-stack wide-line seismic data can further improve the signal-to-noise ratio of the data on the premise of ensuring the correctness of the data processing results, thereby finally obtaining a more ideal pre-stack migration Imaging results.

Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a method for processing pre-stack wide-line seismic data. Background technique [0002] In the process of seismic exploration, pre-stack migration imaging technology is usually used for areas with complex terrain conditions. Since the imaging results of prestack migration imaging directly affect the subsequent interpretation and oil well positioning, prestack migration imaging, as an important part of seismic data processing and oil and gas exploration, plays an important role in seismic exploration in complex areas. played an important role. [0003] In the complex and changeable piedmont zone, the signal-to-noise ratio of the acquired pre-stack seismic data is extremely low due to poor excitation and reception conditions for geological data acquisition. In the prior art, a broad-line observation system is usually used to collect seismic data, and the pre-stack broad-line...
