摘要
Based on detailed field geological investigation, lateral tracing and correlation of lithosomic bodies, profile survey about typical depositional systems and systematic sampling and lab analysis, the composition of genetic facies and reservoir property have been studied about platform margin reef-shoal depositional system of Yijianfang Formation in the Middle Ordovician and platform margin slope-slope fan depositional system of Lianglitake Formation in the Upper Ordovician in Yijianfang outcrop area of western Tarim Basin. The study suggested that platform margin depositional system had complex internal structure,whose genetic facies have relatively fixed space framework and different reservoir properties. Reef-shoal depositional system always developed on the platform margin near the carbonate platform, which consists of reef, bioclastic beach and background deposit of platform margin.
