ln this paper, based on ana1ysis of the remaining oil forming mechanism and distribution law in the buried hillreservoir of Wumishan Formation in Yanling oil field, the potential zones of remaining oil distribution are predicted for thisreservoir- It is shown, that the formation of remaining oil is related to pore structure of the reservoir.
