摘　　要：我国大部分注水开发油田已经进入特高含水期,为了实现稳油控水,寻找合理的注入压力水平,针对魏岗某断块油藏注采系统,从井网储量动用程度、井网密度、注采比评价、压力保持水平四个方面入手,借助油藏数值模拟技术和油藏工程方法,分析了整个断块注采系统的情况,确定了注采压力系统合理组合,对现场注采比调整具有一定的指导作用。Most of the waterflood oilfields have entered into ultra-high water cut stage in China. In order to stabilize oil production and control water cut, and look for reasonable injection pressure level, injection-production system of a Weigang fault block was analyzed by using reservoir simulation techniques and reservoir engineering methods from four aspects of reserves produced degree, well spacing density, injection-production ratio and Pressure maintenance. At last, rational combination of pressure injection-production system was determined.
