摘　　要：单一的岩性或物性参数均无法很好的满足复杂油气藏流体检测的需要。从测井岩石物理参数统计入手,找出与油气特征关联程度高的多个敏感参数进行交会分析,优选出流体敏感参数。基于叠前弹性参数反演成果,探索了井—震联合进行流体检测的方法。通过实际应用,明显的改善了叠后反演的多解性问题,取得了较好的应用效果。Single lithology or property parameters can not satisfy the need of complicated oil and gas reservoirs. Based on a study of statistics of logging rock physies parameters, the authors found several sensitive parameters which are linked intimately with oil and gas characteristics. Based on pre-stack seismic elastic： parameters inversion results, the auttlors explored the fluid detection method by a borehole-seismic comprehensive technique. Practices show that the results obtained by the authors obviously improve the muhi-solution problem of post-stacked inversion, and can achieve good applied effect in the oilfield.
