摘　　要：随着大庆油田油气开发的不断深入，油田含水率逐年升高，目前已进入高含水开发期，水驱开发的主要对象已由水淹程度较高的中高渗透层转变为剩余油富集的薄差储层．以大庆油田杏六中区三次加密井网为例，从含水率、采出程度、经济效益三方面研究薄差油层油井压裂措施技术界限，为油田的增产措施设计提供选井参考依据和理论支撑．结果表明：研究区块存在压裂措施控水潜力，压裂油井选井含水率控制在90％以下，采出程度控制在70％以下可以取得较好的压裂措施效果，并给出了不同油价条件下的压裂措施增油量下限．Along with the process of oil and gas field development, ratio of water cut trends to increase gradually, and now even enter high water cut stage, thin and poor reservoirs of remaining oil enrichment are the potential reservoir using the water flooding development instead of the middle and high permeable reservoirs with high degree of water-flooded. Take Xing 6 Middle Block of Daqing Oilfield as an example, the potential and limits of oil well fracturing of thin and poor reservoirs were studied, the results provide reference and theoretical support for the optimization of fracturing design. The results show that, the block has potential of water control by fracturing, the limit of water cut is 90%, the limit of recovery degree is under 70% and get the limit of oil increment under different oil prices.
