研究表明,东濮凹陷文东地区沙河街组深层碎屑岩岩石类型主要为长石砂岩、岩屑石英砂岩和长石石英砂岩,文东地区沙河街组储层受多因素控制,以沉积作用、成岩作用为主要控制因素,表现为储层岩石结构成熟度低且压实作用强。此外,作者还对构造作用等储层控制因素对该区的影响进行了分析。 The study shows that the deep clastic rocks of Shahejie Formation in Wendong area of ​​Dongpu Depression are mainly feldspar, lithic quartz sandstone and feldspar quartz sandstone. The reservoir of Shahejie Formation in Wendong area is controlled by many factors, , Diagenesis is the main controlling factor, which shows that the rock structure of reservoir has low maturity and strong compaction. In addition, the authors also analyzed the influence of reservoir control factors such as tectonics on this area.
