PRESENT SITUATION AND PROSPECT OF WIDE-AZIMUTH 3D INSPECTION SYSTEM
Feng Kai · 2006
In view of some analyses and comparisons on parameters and attributes of several kind of common inspection system used in production practice at present, such as wide-azimuth and narrow-azimuth inspection system, multi-line receive and repeat shot points wide-azimuth inspection system, land water system area and shallow-beach transitional zone wide-azimuth inspection system, the authors indicate the wide-azimuth inspection system of the 3D seismic data acquisition is a technology which at present and even the certain time in future should be supposed to popularize massively. It is put forward that the most ideal target is the omni-directional 3D seismic acquisition inspection system in which, the trace-spacing, the receive line-spacing and the shot point-spacing are completely regular and equal, and it is indicated the popularization of the ocean bed cable (OBC) technology, ten-thousand-trace acquisition system in land and PC cluster technology will make the 3D seismic acquisition of the omni-directional, the high density and the high cover inspection system possible.
