[0020] In the process of multi-wave seismic data processing, whether an accurate residual static correction value of converted wave can be calculated is directly related to the quality of converted wave data processing. Usually people use the common detection point superposition method to obtain the residual static correction amount of the converted wave. Therefore, it is necessary to perform velocity analysis based ...

Abstract

The invention provides a common detection point data gather velocity analysis method. The method comprises the steps that 1 a common detection point data gather to be subjected to velocity analysis is transformed to acquire a pseudo-co-center point data gather; and 2 velocity analysis is carried out on the pseudo-co-center point data gather through a co-center point velocity analysis technology to acquire superposition velocity based on the common detection point data gather. According to the invention, the method is used for common detection point data gather velocity analysis in multi-wave seismic data processing to acquire accurate superposition velocity based on the common detection point data gather, and an accurate common detection point data gather superposition result is provided for acquiring accurate conversion wave remaining static correction amount.

Description

Technical field [0001] The invention belongs to the field of geophysical prospecting, and specifically relates to the technical field of multi-wave seismic data processing. Background technique [0002] Due to the increasing complexity of underground oil storage structures, the data and information provided by conventional longitudinal wave exploration technologies have been difficult to meet the needs of seismic exploration. In order to meet the requirements of finding oil storage structures, multi-wave seismic exploration technology has begun to be applied to seismic The field of exploration has become an important branch of this field. Compared with conventional longitudinal wave exploration techniques, multi-wave seismic exploration provides much more information about underground structures. How to extract the seismic information related to underground oil storage structures is multi-wave The only goal of seismic data processing is that compared with conventional seismic exp...
