| 摘 要： | 针对川西地区新场气田超高压气藏，利用三维采集的地震资料，在改善叠前CDP道集信噪比和速度谱质量的基础上，采用等时间隔层速度法，根据Fillippone的压力计算公式，直接预测地层压力，得到了全三维的压力和偏差压力数据体。压力预测结果表明，该方法具有较好的可信度。

| 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. |
