摘　　要：研究大民屯凹陷西部沙河街组已知油气藏类型和油气藏分布规律,认为该区沙四段发育有安福屯、平安堡等多个生油洼陷,其南北与荣胜堡洼陷、三台子洼陷相接,油气成藏条件优越。油气藏类型主要包括构造油气藏、岩性油气藏及构造-岩性油气藏3种。从生储盖组合特点、断层特征、圈闭形态与源储特征等方面研究其对油气成藏的控制作用。This paper studies it deeply on types and distribution law of known hydrocarbon reservoirs of shahejie formation of western slope in damintun sag. The results show that there are four oil generation sags of Es4 in the study area, including pingan Pu, anfu Tun, rongsheng Pu and santaizi subsag. The types of reservoir in this area include structural reservoirs, lithologic reservoirs and structural -lithologic reservoirs. By analyzing source -reservoircap rock assemblages characteristics ,fault characteristics, trap geometry and source -reservoir relationship, their con- trol on oil pool formation has been studied.
