摘　　要：Y地区发育不同组合类型砂体,受储层岩性、物性、非均质性等因素影响,气水关系复杂;富气河道构造低部位储层也比较发育,但气水过渡带难以准确预测。针对以上问题,利用地震数据在时间域和频率域的优势,开展高精度弹性参数叠前直接反演,以致密碎屑岩岩石物理建模为基础,综合多种弹性参数实现岩石物理参数联合反演,降低参数耦合效应,提高参数预测精度。为川中Y地区沙溪庙组河道砂体的高效开发提供了有利的支撑。Sand bodies of different combination types are developed in region Y,Affected by reservoir lithology,physical property,heterogeneity and other factors,The relationship between gas and water is complicated.The reservoir in the low part of the gas-rich channel structure is also relatively developed.But the gas-water transition zone is difficult to predict accurately.In response to the above problems,Taking advantage of seismic data in the time domain and frequency domain,Carry out high-precision pre-stack direct inversion of elastic parameters,Based on petrophysical modeling of tight clastic rocks,Combining various elastic parameters to achieve joint inversion of petrophysical parameters,Reduce the parameter coupling effect,Improve the accuracy of parameter prediction.It provides favorable support for efficient development of channel sand body of Shaximiao Formation in Y area of central Sichuan.
