The Application of MultiWave and MultiComponent Joint Inversion of Seismic Data to S Oilfield in Tabei Uplift, Tarim Basin

Abstract

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
