本文研究区为川东地区 ,在对其沉积发展史研究的基础上 ,分别在川西、川东、川南选择了三个典型的露头剖面 ,进行地面露头的层序地层学分析 ,并结合井下 (梁向 1井 )剖面资料划分出基本的二、三、四级程序 ,进而在研究区内东西向、南北向剖面进行井间层序划分对比 ,从而建立起川东地区上二叠统层序地层模式 ,为生物礁的预测提供了有力的理论依据 Based on the research on the history of depositional development in this area, three typical outcrop sections were selected in western Sichuan, eastern Sichuan and southern Sichuan for sequence stratigraphy analysis of outcrops in the study area, Liangxiang 1) profile data are divided into basic two, three and four levels program, and then in the study area east-west, north-south section cross-well sequence comparison and comparison, so as to establish the East Sichuan Permian sequence Stratigraphic model provides a strong theoretical basis for the reef prediction
