摘　　要：为探究地震叠前反演预测淮南煤系地层非常规天然气储层中过程,非常规天然气储层弹性、物性等之间的规律,基于现有的淮南实际矿区测井资料,通过建立岩石物理模型来校正、优化密度、纵波阻抗、横波阻抗等测井曲线,并对优化后的测井曲线进行统计分析,分析了非常规天然气储层的岩石物理敏感参数,揭示了储层弹性与岩性、物性之间的关系,为淮南地区非常规天然气储层评价、预测以及高效开采提供保障。In order to explore the law of unconventional gas reservoir elasticity and physical properties in the process of seismic prestack inversion prediction of unconventional gas reservoir in Huainan coal measure strata,based on the existing logging data of Huainan actual mining area,the density,P-wave impedance,S-wave impedance and other logging curves were corrected and optimized by establishing a petrophysical model,and the optimized logging curves were statistically analyzed.The petrophysical sensitive parameters of unconventional gas reservoir were analyzed,and the relationships between reservoir elasticity and lithology and physical properties were revealed,which provided guarantee for unconventional gas reservoir evaluation,prediction and efficient exploitation in Huainan area.
