摘　　要：针对深海边际断块油田岩层开采难度高、经济投入大风险高等问题,利用油藏工程和数值模拟手段,对海上边际断块油藏开发方式进行研究,主要论证了开发井型,布井位置、井数、产液速度等开发参数,并对后期生产井转注进行了分析。最终得出该类油藏最优开发方式为初期采用天然能量开发,中期调整注水补充能量。井网优化和地层能量的补充对该类油藏尤为重要。在提高采收率的同时也可节约开发成本。It is difficult to develop the rock stratum,and the economic risk is high in the marginal fault block oilfield.The first demonstration of development well.And then set up the numerical model,the development mode of the reservoir is put forward.Next the well location,well number,production rate and other development parameters are determined.Finally,the production wells by injection water is considered.The best way for the development of this type of reservoir is to use natural energy in early stage and adjust water injection toreplenish energy in middle stage.Optimization of the well patterns and complement formation energy are important to the reservoir.Increasing the recovery rate and saving the development cost.
