摘　　要：旺隆-太和-宝元构造嘉陵江组地层为一套浅海碳酸盐岩沉积,嘉五1段储层以孔、缝、洞发育为特点,属于裂缝-孔隙型储层。嘉五1储层测井曲线的相应特征表明,含气后阻抗明显降低,因此对其地震预测主要采用波阻抗反演。结合储层的地质、测井、钻井特征及地震波阻抗反演分析,得到嘉五1储层综合预测平面图。The Tlj stratum of Wanglong - Taihe-Baoyuan stlucture is a set of shallow sea carbonate sediments. T1j5^1 reservoir belongs to fracture pore type characterized by pore, slot and hole. The characteristics of T1j5^1 logging curves indicate that impedance reduced distinctly with gass.The seismic prediction is adopted mainly by wave impedance inversion. Combined with the characteristic of geology, logging and drilling and seismic wave impedance inversion analysis, we can get comprehensive prediction plane of T1j5^1reservoir. It has an important directive function for the exploration of that area.
