摘要

在层序界面识别基础上,综合利用野外露头剖面、钻井岩心、测井和地震资料等,运用经典层序地层学理论,对川西地区海相中二叠统层序地层进行对比与划分,川西地区海相中二叠世划分6个三级层序,建立川西地区海相中二叠统层序地层格架,其中,栖霞组(P2q)储层分布于SQ5层序的高位期,茅口组(P2m)储层发育于SQ6层序顶部。
On the basis of sequence stratigraphic division,and comprehensively using the data of outcrops,drilling cores,logging and seismic data,middle Permian sequence stratigraphy was divided and correlated in west Sichuan Basin by using the theory of sequence stratigraphy.It is divided into 6third-order sequences.And sequence framework is established in the western Sichuan Basin,in which the reservoir of Qixia Formation is in high position of Sequence SQ5,the reservoir of Maokou Formation is on the top of Sequence SQ6.
