海通集洼陷地层划分与对比的新认识

由于海通集洼陷钻井较少,所以以前对该区地层对比的研究也较少。根据对濮深１４井等地质资料的再分析,结合重新处理的三维地震资料,并与邻区进行对比和分析,拉通了本区与文西断阶带的地层对比剖面,建立了海通集洼陷标准地层剖面,特别是对沙三＾２段提出更为确切的划分依据,探讨了文９盐在本区的变化规律,为开展其他各项研究工作奠定了基础。

Stratigraphic Classification and Correlation in Haitongji Depression

Only a few wells had been drilled and few works had been done on the stratigraphic correla tion of Hai Tongji depression in the past. In this paper,based on reanalysis of geological information, and strati graphic correlation of PS14 well and the wells in neighbour area, combined with 3-D seismic information, It makes the relation of stratigraphic in this arca and Wen Xi step faults belt clear, and established a standard strati graphic section in Hai Tongji depression. The special achievernents of this paper lies in its more accurate basis provided for the classification of Ns23 formation and study lateral distributive regulation of "Wen 9 salt" forma tion,thus laying the foundation for other works in Hai Tongji depression.
