俄联邦多数油田己进入晚期开发阶段，原油含水已很高，在调整注水开发方案和处理井底油层等方法对提高石油采收率效果明显下降的情况下，本文提出一种用木屑堵水工艺来提高注水油田高含水期开发效果。本文主要叙述了该工艺的作用机理和方法，并给出了木屑堵水工艺在一些油田上的 推广应用结果。
Most oilfields of the Russian Federation have entered the late stage of development and the water content of crude oil has been very high. Under the circumstances that the effect of adjusting the water injection development scheme and handling the bottom oil layer is obviously decreased on improving the oil recovery rate, To improve the high water cut waterflooding oilfield development effect. This paper mainly describes the mechanism and method of the process, and gives the popularization and application results of sawdust water-blocking technology in some oil fields.
