| Abstract: | The analyses of the accumulation conditions of lithologic reservoir in Tanan sag showed that，for the open multiplex and half graben like faulted structures，the tectonic framework of the convex concave and concave uplift alternated formed in Tanan sag，which created favorability for the formation of the lithologic reservoir； The high quality source rocks developed in the sedimentary center of Nantun Formation were material foundation of the development of the lithologic oil reservoirs； Synsedimentary fault and its configuration decided the characters of gullies controlling sources，transform zones controlling fans and faulted slopes controlling sands，and that the middle fan of subaqueous fan，delta front and infralittoral subaqueous fan were the the most favorable hydrocarbon accumulation zones； The phase changes of the oil in the reservoir，rich volcanic debris and the development of the faults make the deep oil gas accumulation more development，which provided effective reservoir space for the development of the lithologic oil reservoir； Tectonic activity and sedimentary evolution formed the optimal configuration relationships of the source reservoir cap，which created favorable conditions for the formation of multi types lithologic oil reservoirs.According to the lithologic oil reservoir types，spatial distribution characteristics and oil accumulation characters in Tanan sag，four kinds of lithologic oil reservoir forming modes are summarized，including the fault terrace steep slope break belt，fault terrace gentle slope break belt，cliff steep slope break belt and inner basin slope break belt reservoir forming mode of Tanan sag，combining the geological structure characters and fault slope break types of each sub sag in Tanan sag and the study results of the lithologic reservoir forming mode in Bohai Bay，Erlian Basin. |
