摘要: 针对湖南保靖地区地表覆盖层复杂、地下高陡构造多变、地震勘探资料信噪比低,以及页岩气储层与周围泥岩层波阻抗对比度小等特点,研究敏感测井曲线重构与优化处理、地震资料相控非线性反演和叠后地震属性流体检测的综合储层评价方法。通过对多条测线的地震资料反演和流体检测并与实钻井结果对比,获得了良好的地质效果,初步验证了所研究方法的有效性和实用性。Abstract: Facing the difficulties of various near surface formations in Baojing area, Hunan province, and significant tilt of the subsurface formation and structure, and hence caused low signal/noise ration of the seismic data, and the low contrast of seismic impedance between the shale gas reservoir and the shoulder shale, we have investigated integrated evaluation method that consists of four steps of sensitive well logs reconstruction and optimal processing, nonlinear inversion of seismic data constrained with sedimentary facies, and fluid detection by using poststack seismic data. Comparison of the seismic inversion results and fluid detection results of several inlines with that of the borehole shows sound consistency, and verified the effectiveness and practical usefulness of our method.
