Due to the complexity of both the surface and the subsurface geological structures in the Keshen section of Kelasu Tectonic Belt in the central part of Kuqa Depression, resulting in the seismic imaging difficulties, the conventional 3D data can hardly meet the demands of the precise evaluation and development of gas reservoir. For improving the imaging accuracy of the complex deep subsalt structures, the high-precision 3D seismic acquisition technology characterized by high density and wide azimuth is carried out for the first time in the zone for a brainstorming application. The technical - economic integrative application of the high-density 3D acquisition technology in complex mountains is realized and the seismic imaging accuracy is greatly improved by adopting the prestack depth migration processing demand oriented 3D geometry design technology, the high S/N ratio broadband shooting and their supporting implementation technologies as well as the single-point broadband receiving and its supporting implementation technologies, which lays a data foundation for the evaluation and development of deep complex reservoirs.
