摘要(Abstract)：
高含水后期分层采油技术是在精细地质研究基础上,依靠细分注水、细分采油工艺技术对油水井不同水淹层位进行分压力系统注采,旨在提高弱水淹层位(部位)动用能力,控制强水淹层位(部位)的产液强度。通过初步实践证明,机采方式下的分层采油技术可以实现高含水后期,控含水、控递减,治理无效循环的目的。
Separate zone production in the late high water cut period is used to increase the productivity of weak water flooding zones or parts and to control the produced fluid intensity in high water flooding zones. It is based on the fine geologic research, relying on subdivision technology of water injection and oil production under separate pressure systems for oil wells and water wells in different water flooding zones. Initial practice has showed separate zone production technology can control the water cut, production decline and invalid water circulation in the late high water cut stage under the mechanical oil production mode.
