充分利用已有的钻井、测井、录井、地震等资料 ,应用地震地层学、层序地层学和沉积学理论 ,对准噶尔盆地东部五彩湾 -石树沟地区的中二叠统层序地层进行研究。将中二叠统将军庙组至平地泉组划分为一个层序 ;又根据不同的沉积组合和几何形状 ,把将军庙组划分为低水位体系域 (L ST) ,平地泉组三段至二段下部划分为湖侵体系域 (TST) ,平地泉组二段下部至一段划分为高水位体系域 (HST) ,凝缩段难以确定。低水位体系域主要为冲积扇、滨浅湖沉积 ,湖侵体系域为半深湖 -深湖、水下扇沉积 ,高水位体系域为扇三角洲前缘、水下扇沉积
Making full use of the data of well drilling, well logging, logging and seismic and so on, we apply the seismic stratigraphy, sequence stratigraphy and sedimentology theory to study the Middle Permian sequence stratigraphy of Wucaiwan-Shishuogou area in the eastern Junggar Basin research. The Middle Permian Jiangjunmiao Formation to Pingdiquan Formation is divided into a sequence. According to different sedimentary assemblages and geometric shapes, the Jiangjunmiao Formation can be divided into LST, Pingdiquan Formation three to two The lower part of the segment is divided into TST. The lower part of the second part of the Pingdiquan Formation is divided into a high-water mark (HST) and the condensing section is difficult to be determined. The lowstand system tract is mainly alluvial fan, shallow foreshore and lake sedimentary system. The lacustrine system is semi-deep lacustrine-deep lake and subaqueous fan. The highstand system tract is fan delta front and submarine fan deposits
