摘要
川东地区在早三叠世飞仙期沉积环境是在继承晚二叠世沉积环境的基础之上发展起来的 ,台地上相带分化明显 ,广泛的发育鲕粒滩体 ,滩体随着台地的发展而逐渐迁移。根据勘探资料 ,可以划分出 4个较厚的鲕粒岩分布区。川东飞仙关组目前已钻获众多的鲕滩工业井 ,其储层均位于鲕粒岩发育较厚的区块的溶孔白云岩及溶孔灰岩中 ,并获得了较大的工业储量 。
In the eastern Sichuan basin, the sedimentary environment of early Triassic inherited that of late Permian. The zonation in the platform was obvious with well-developed oolitic shoal. Migration of shoal occurred in the process of platform development. Four relatively thick oolitic rock area could be classified in reference to the drilling data. Mang industrial gas wells have been drilled in the oolitic shoal of Feixianguan Formation in the eatern Sichuan basin.The result showed that the reserriors lay in the dolomite and limestone with solution pore in the thick oolitic rock area where abundant industrial gas reserve has been obtained.Therefore, the oolitic shoal rock in Feixianguan Formation in the eatern Sichuan basin pocessed great exploration prospect of gas.
