Research and Practice of Cyclic Water Flooding in Horizontal Well of Fluvial Reservoir——B y Taking Bohai N Oilfield as the Example
摘要
Abstract
In this paper,Bohai N oilfield is taken as an example for horizontal well oriented development interlayer reservoir,to carry out alternate cycle water injection,because the water content rises fast and there is low utilization of reserves.The results show:for these reservoirs,the alternating cycle injection is better than conventional water flood development cycle injection.In the strong injection half cycle,injection-production ratio improving to 1.3 can control water coning speed to a certain extent and reduce water cut in production wells.In the weak injection half cycle,the injection-production ratio controlled at about 0.8, can delay the time that the injection of water breaks through to the bottom of the well.According to the results,field pilot tests of 2 injection in 2 wells are car-ried out,water cut decreases by 1%to 14%,the average increasing oil rate is 6~22 m3/d.关键词
