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。
Aiming at the characteristics of complex surface cover, high and steep subsurface structure in the Baojing area, low signal-to-noise ratio of seismic exploration data and low contrast of wave impedance between shale gas reservoir and surrounding mudstones, Optimization treatment, seismic inversion of non-linear seismic data and post-stack seismic attribute fluid detection integrated reservoir evaluation method. Through the seismic data inversion and fluid detection of multiple measuring lines and the comparison with actual drilling results, good geological effects are obtained, and the validity and practicability of the proposed method are verified.
