The study of forming conditions of fault block oil reservoir in Beier Depression shows that the accumulation conditions were superior. The main controlling factors of hydrocarbon accumulation were sealing characteristics of faults, tectonic setting and types of sand body, etc. And there were three kinds of hydrocarbon accumulation modes, which were respectively controlled by sand bodies connecting carrier beds, unconformity carrier beds and fault carrier beds. This paper systematically analyzed hydrocarbon accumulation conditions in Nantun Formation in western slope belt of Beier Depression, summarized controlling factors of oil reservoirs and established perfect hydrocarbon accumulation mode, which had certain guiding significance in the exploration of Nantun Formation. Key words: Beier Depression,western slope belt fault block oil reservoir hydrocarbon accumulation mode controlling factor. 员 成藏因素 气藏遥生油研究证实 贝尔凹陷大磨拐河组下段或南屯
