| 摘 要： | 常规地震资料解释主要利用纵波来识别岩性和检测气水层,其结果多解性较大,而利用多分量地震资料提供的纵波和转换波速度及由此导出的泊松比、纵速度比、纵波、道积分和转换波的波阻抗反演联合解释来直接预测含油气性,预测结果与实际情况吻合很好,说明利用多波资料能提高地震预测油气藏的可靠性和精度.

| Abstract: | In interpretation of conventional seismic data, p-wave is used to detect lithology, gas and oil. The results are not one and only. Using multi -components seismic data which have much seismic information can reduces possible mutli-result. In this paper , we use p -wave and ps -wave velocity of multi -components seismic data and their velocity ratio, Poisson ratio, quadrature trace and impedance of p -wave and ps -wave to predict gas and oil in reservoir. The predicted results are the same as that of drilling. This study shows that using multi -components seismic data can enhance the precision and reliability of prediction of reservoir. |
