Abstract: High resolution 3-D seismic exploration in panel clearly detected the gateways that depth of burial of 460 m, section of 3.2 m× 3.8 m, at a distance of 50 m. It has not been reported at home and abroad. this paper expounds the detection of forming reflection waves by gateways-the particular geological bodies and their display features in 3-D data bodies. From which several pieces of useful enlightenment are resulted.
