川东地区北部飞仙关组储层特征及分布

Reservoir Characteristics and Distribution of Feixianguan Formation in North Part of East Sichuan

本文探讨了使四川盆地川东地区北部下三叠统飞仙关组滩相岩类储集性得以改善的白云岩化作用,滩相白云岩化储层的储集性及孔隙白云岩发育的控制因素。最后指出,以龙会场——福成寨——福禄场形成的三角地带是滩相孔隙白云岩储层分布的有利区。

The dolomitization of improving reservoir nature of beach facies rocks in Feixianguan Lower Tri- assic in the north part of east Sichuan Basin and the control factors of reservoir nature of beach facies dolomitic reservoir and porous dolomite growth are discussed in this paper. Finally, it is pointed out that the deltaic area consisted of Longhuichang, Fuchengzhai and Fuluchang is the favorable zone of refer- voir distribution of beach facies porous dolomite.
