实施不稳定注水提高井组稳升率

Implementation of Unsteady Flooding to Improve Rise Rate for Wells Group

不稳定注水是提高水驱开发的一种重要手段,它能够提高注入水波及系数,控制含水上升速度,最终达到提高采收率的目的。针对坨85断块平面矛盾突出、含水上升快、多次调整注采关系,减缓油井含水上升速度效果均不明显的特点,在该断块实施不稳定注水,取得了控水增油的效果,达到改善区块开发效果的目的。

Unsteady flooding is an important means to improve water flooding, which can improve the injection of waves and the coefficient, control moisture rising velocity, and ultimately to improve oil recovery purposes. For flat contradiction Tuo 85 fault block, water rose quickly, repeatedly adjust the injection and production relations, slowing the speed of the effect of rising water cut wells are not obvious features in the block implementation of the unstable water, water control achieved by the effect of oil, achieve the purpose of improving the effectiveness of block development.
