【摘要】 为了提高波阻抗反演的分辨率,在密度资料对反演结果产生重要影响的基础上,利用岩心、测井及地震资料,从岩石物理性质-测井响应-地震响应角度分析,提出应用测井-地震多属性密度曲线重构技术合成拟密度曲线,其结果用全井连续取心样品测试分析数据验证的平均误差为0.05g/cm3。应用反演效果分析表明,反演结果吻合率从重构前的78%提高到重构后的86%,密度曲线重构反演技术提高了反演精度和分辨率。更多还原

【Abstract】 To improve the resolution of inversion,based on the fact of that the density data in a great impact on inversion results,making using of the core data,logging data and seismic data,from this perspective of analyzing the physical properties of rock-logging response-seismic response,the log-seismic multi-attributes density curve reconstruction technique was proposed to synthesis the pseudo-density curve.The results was verified with the analyzed data of the entire well continuous coring samples and the average validation error is about 0.05 g/cm3.The practical application shows that the coincidence rate of inversion results increase from the 78% to 86% after reconstruction.This can be concluded that the density curve reconstruction inversion technique can improve the precision and resolution of inversion.更多还原
