摘　　要：海拉尔油田属于复杂小断块油藏,自然递减和含水上升速度难以有效控制已严重制约油田的开发。通过不断深化油田地质认识、精细油藏描述,系统研究了不同类型油藏注水受效规律。针对不同类型油藏注水受效特征及主要开发矛盾,实施了针对性的综合调整。从而形成了一套适合海拉尔复杂小断块油藏的综合调整技术系列,实践表明该技术可有效控制油田产量递减率、含水率上升速度,应用前景广阔。Haila'er Oilfield belonged to a small fault block complex reservoir,it was difficult for effectively controlling the natural decline and water cut rising velocity,which seriously restricted the oilfield development.Based on the deepening geological understanding,fine reservoir description,the effect law of water flooding of different reservoirs was studied.According to the water flooding characteristic and main development contradictions,comprehensive adjustment was carried out.Then the comprehensive adjustment technology was formed for the small fault block complex reservoirs of Hailaer Oilfield.Practice shows that it can effectively control the natural decline of production and water cut rising velocity,which has broad application prospects.
