摘　　要：针对油藏地质特征进行再认识,分析目前开发现状,通过对目前注水技术、方式和注采关系的适应性研究,调整注采井网,提出可操作的精细注水和稳油控水综合治理对策,达到控制油井含水上升、减缓产量递减,提高地质储量动用率。为保持区块稳产,取得好的注水开发效果奠定基础。N oilfield is a low porosity and low permeability oilfield,which is difficult to exploit and has high technical requirements.Through years of research and production practice,a breakthrough has been found,that is,fracturing and water injection to the target layer.However,with the continuous water injection of the reservoir,some problems also appear.In view of the problems in water injection development,only some adjustment can not be solved.Through the evaluation of water injection development effect of N oilfield,find out the factors affecting the development effect,analyze the problems existing in development,explore comprehensive treatment measures,improve the water injection development effect,and achieve the purpose of improving the final oil recovery of the reservoir.
