The Sulige area is an important area of natural gas exploration and development with complex surface conditions and lateral variable continental sedimentary reservoirs. In recent years, in view of the complex geological conditions and the Paleozoic gas exploration, the higher-coverage acquisition techniques with long array, small interval and single digital receiver were formed through the seismic exploration study of the all-digital seismic acquisition,processing and interpretation. The seismic pre-stack processing techniques, pre-stack inversion and post-stack interpretation methods have been gotten many achievements. All above could meet the needs of seismic pre-stack effective reservoir prediction and help the rapid and efficient exploration and development in the Sulige area.
