辽河坳陷西部凹陷西斜坡齐40块地质概况研究

摘要

齐40块地层发育完整，根据现有的井资料显示，钻遇地层自下而上依次发育的是下第三系沙河街组沙三段、沙一段和沙二段及新近系馆陶组、明化镇组和第四系平原组地层。从区域概况，地层概况，构造特征和储层特征这4个方面来描述其地质概况，通过研究能对下一步勘探开发提供一定的指导意义。%The formation of Qi40 block is well developed.According to the current well data,the sequence of bottom-up development of the stratum is Shahejie Formation,including Shahejie Formation,Shahejie Formation and Neogene Guantao Group,Minghua town group and Quaternary plain group.In this paper,the geological profiles are described from four aspects,such as regional profiles,stratigraphic profiles,structural features and reservoir characteristics,which can provide some guidance for the next exploration and development.
