注水开发后期油藏调整技术研究

Study on Reservoir Adjustment Technology in the Late Stage of Water Injection Development

对注水开发后期油藏开展精细地质研究,落实构造,寻找局部构造高点及断层遮挡圈闭等剩余油富集区域。从沉积相角度出发,认识储层平面及纵向上的非均质性,挖掘水淹程度弱、剩余油富集区域,进行开发调整并取得了较好的效果,为类似油藏的开发调整提供了新的思路。

In the late stage of waterflooding development,the reservoir develops a fine geological study,implements structures,and seeks for remaining oil-enriched areas such as local structural highs and fault-blocking traps.From the viewpoint of sedimentary facies,the understanding of heterogeneity in the reservoir’s plane and longitudinal direction Sex,digging weak flooding areas,and remaining oil-rich areas,carried out development adjustments and achieved good results,providing new ideas for the development and adjustment of similar oil reservoirs.
