A lithologic trap model has been established to simulate hydrocarbon migration and accumulation in sand lens reservoir. The differences in the process and mechanism of hydrocarbon accumulation in sand lens reservoir under different geologic conditions have been confirmed. Episodic accumulation is outstanding for high efficiency and high speed.Hydrocarbon-source conditions, transport conditions, the distance between source rocks and reservoir rocks as well as sand body properties control the formation of sand lens reservoir.
