PP-PS JOINT INVERSION TECHNOLOGY AND ITS APPLICATION TO GAS RESERVOIR PREDICTION
讨论了利用PP波和PS转换横波进行叠前联合反演的理论和实现方法,结合某油田实际多波地震资料,在叠前联合反演的基础上,对深层火成岩气藏进行了含气性预测.经钻井资料验证,根据联合反演资料预测的气藏结果与井资料吻合较好.实践证明,纵横波叠前联合反演可以避免单纯使用纵波信息进行弹性反演而造成的岩石弹性参数的多解性,提高气藏预测的准确性.
This paper investigated the theories and methods of prestack joint inversion hy utilizing PP and PS converted wave data sets. Actual multi-component seismic data from the oilfield were also used to delineate the deep buried volcanic gas reservoir based on the studied methods. Well log data show that the gas reservoir prediction results are consistent well with the well data, suggesting that prestack PP - PS joint inversion can avoid the multiple solutions of…查看全部>>
