摘要： 三叠系是塔里木盆地S油田主要含油气层，三角洲前缘砂岩储集层物性好，但含气后纵波速度趋近于泥岩。以地震多波多分量资料为基础，用测井资料分析确定了有效储集层敏感参数；在纵波、转换波精细标定及匹配的基础上，开展纵波、转换波联合反演，得到了纵波阻抗、横波阻抗、纵横波速度比等参数。用横波阻抗有效识别出砂岩分布特征，用纵横波速度比预测了储集层的含油气性。结果表明，多波资料储集层预测较单一纵波预测精度更高。

Abstract: The Triassic is the major exploration area of S oilfield in Tarim basin, with good physical property of sandstone reservoir in the delta front sedimentary facies. However, its P?wave velocity of gas?bearing sandstone appears to that of mudstone velocity. Based on the multi?wave and multi?component data, the effective reservoir parameters are determined by the crossplot of logging data. According to the fine calibration and P?wave and PS?wave match, the joint inversion is carried out to get those parameters, including P?impedance, S?impedance, vp /vs . The S?impedance is used to accurately identify the sandstone distribution, and the hydrocarbon property of reservoirs is predicted by vp /vs . The study result shows that the reservoir prediction by using multi?wave data is more accurate than that of P?wave data. It provides important information for the well deployment of the oilfield
