Abstract: 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.
