本文通过对柴窝堡凹陷永丰次凹、达板城次凹中各时代地层的若性特征、赋存状况、沉积环境、断裂性质及展布诸方面的综合分析,探讨了凹陷的构造演化,并结合凹陷的构造格局,形成圈闭的时空配套关系和热演化史的研究,分析了油气的富集规律和含油气远景。提出了今后的勘探设想。

Through the comprehensive analysis of the lithologic feature,enrichment condition,sedimen tary environment,fracture behavior and distribution of various epoch strata in the Yongfeng andDabanchen subsags of the Chaiwobao sag,the structural evolution of the sag has been approached.Combining with the study of the structural framework. time space coordinative relation,and ther-mal evolution history of the sag, I analyze the hydrocarbon enrichment law and potential. The fu-ture exploration assumption is put forward in the paper.
