摘　　要：柳洛峪区块1996年初期勘探在三叠系长2段发现了油层。2006年泉40-1开始试注水,月注水量372m^(3),到2017年12月,开始转注4口井,后期注水井陆续增加,到2012年1月注水井增加到53口,月注水量17837m^(3),开始规模化注水。受层间矛盾、平面矛盾、层内矛盾,水驱状况的影响,不同区域剩余油分布规律不同,不同层位剩余油分布规律不同。oil layer was found in Chang 2 member of Triassic in the initial exploration of liuluoyu block in 1996.In 2006,quan40-1 began trial water injection,with a monthly water injection volume of 372m^(3). By December 2017,it began to inject 4 wells. Later,the number of water injection wells gradually increased. By January 2012,the number of water injection wells increased to 53,with a monthly water injection volume of 17837m^(3),and large-scale water injection began. Affected by interlayer contradiction,plane contradiction,interlayer contradiction and water drive condition,the distribution law of remaining oil in different regions and different horizons is different.
