| Abstract: |
| A new technique is proposed in the present paper for the three-dimensional pressure prediction of the super-high pressure gas deposit of the Xinchang Gas Field in western Sichuan. The technique is employed by using the time-equivalent interval velocity and Fillippone's formula on the basis of the three-dimensional seismic data and improved S/N ratios of the pre-stack CDP gather and velocity spectrum, and then the three-dimen-sional pressure and deviation pressure data can be computed directly. As a result, this technique turned out to be feasible, and may provide an important base for the oil and gas exploration and development. |
