天然气饱和度预测方法研究及应用

摘要

基于对AVO技术研究现状的深入调研，重点研究了基于叠前地震资料预测天然气饱和度的线性岩石属性变换的犖犐反演方法，探讨了如何对反演结果进行敏感性分析来正确预测有商业开采价值的天然气储层。实际应用结果表明，本文提出的天然气饱和度预测方法可行有效。%Based on probing into the research sta-tus of AVO technique,a NI inversion method oflinear rock-attribute transformation was emphati-cally researched,which can be used to predict gassaturation on a basis of prestack seismic data.Furthermore,it was discussed how to make thesensitivity analysis of the inversion results in orderto correctly predict commercial gas reservoirs.The practical applications have shown that thismethod to predict gas saturation is feasible and ef-fective.
