Creating a new brilliance of mountain seismic exploration in sichuan basin

In the paper, after having reviewed the course of developing mountain seismic exploration for 51 years in Sichuan and the glorious achievements obtained and in light of the problems existing in the seismic exploration in Sichuan, the methods of carrying out exact static correction are proposed; it is considered that the exact migration imaging of single fold data received by the geophones in shot-holes can be finished by use of CT and τ-P layer-stripping methods; it is painted out that, through raising the resolution factor of original data, the effectiveness of predicting oil-gas-and water-bearing strata can be improved; and it is put forward that, for the high-steep structures in the high mountain, region of East Sichuan, the single-fold 3-D acquisition test received by the geophones in shotholes is a correct method and the high-angle formation may be correctly determined by use of the shooting and receiving techniqus carried out in deep development wells. The novel and high-quality products used for the methods mentioned above will dominate the domestic and foreign markets, thus creating a new brilliance of mountain seismic exploration.
