【摘要】 弹性波阻抗反演是近年来地震反演技术的一个"亮点",也是反演研究的热点。由于弹性波阻抗反演包含转换横波的信息,其结果不仅能更好地区分岩性,而且能够预测油气等流体。在论述了弹性波阻抗概念和原理的基础上,介绍了其反演用于储层描述的地质效果。在大量资料调研的基础上,认为角度或偏移距叠加反演与AVO反演相结合、弹性波阻抗与声波阻抗反演相结合的联合反演将成为地震数据解释的新方法。更多还原

【Abstract】 The elastic wave impedance inversion is a "bright point" of the seismic inversion technique in recent years, and al-so a "hot point" of the inversion research. Using this technique, we can not only distinguish lithologies but also predictfluids such as hydrocarbon because the elastic wave impedance inversion includes the converted transverse wave. Thegeologic effects of doing reservoir description by this technique was introduced based on the concept and principle ofthe elastic wave impedance. Through study on large quantity of data, we considered that the combination of the angleor offset stack inversion and AVO inversion, and the combination of the elastic wave impedance inversion and accous-tic impedance inversion will be the new seismic data interpretation method in the future.更多还原
