雁翎油田雾迷山组潜山油藏剩余油分布与预测

提高高含水期裂缝性碳酸盐潜山油藏开发效果的关键是预测剩余油的分布。在分析雁翎油田雾迷山组潜山油藏剩余油形成机理及其分布规律的基础上，对该油藏的剩余油分布潜力区作了预测。剩余油的形成与储层层的储集空间结构密切相关，剩余油的分布形式可分成微观和宏观两种，预测该油藏的剩余油主要分布在岩块油水界面以上，远离主断层井区，井间油水界面低凹区，流动屏蔽层完整分布部位以下以及水淹带Ⅲ类储集层区。

DISTRIBUTION AND PREDICTION FOR REMAINING OIL IN BURIED HILL RESERVOIR OF YANLING OIL FIELD

The key to enhance the development efficiency of fractured carbonate buried hill reservoir is the prediction of remaining oildistribution. 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. Remaining oildistribution has two patterns. It is predicted that the remaining oil of this reservoir is mainly located above the oil-waterinterface, in wells far from the main fault, in crosswell low water-oil level zone, in flow barrier lay6r and watered-out zone oftype 3 reservoir. The research results provide a scientific geological basis for the successful pilot test of N,-injection.
