摘　　要：我国东部大部分油藏属于注水开发油田,随着这些油田大部分进入特高含水期,油田的常规注水开发效果越来越差,挖潜的难度也越来越大。要利用不稳定注水技术对进入特高含水期的油田进行高效开发,提高挖潜效率,必须了解特高含水期油田不稳定注水的机理及适用条件。以双河油田437块Ⅱ1-2层系为实例,利用油藏工程和油藏数值模拟方法,研究特高含水期油田不稳定注水驱油机理,得到特高含水期油田进行不稳定注水的适用条件。The development of oilfields in Eastern China is mostly water flooding, with these oilfields entering into extra high water cut period. The effort becomes worse and worse, which makes tapping potentiality more difficult. In order to use the unstable water injection technology to develop those oilfields efficiently for enhancing oil recover- y, it is necessary to make clear for the enhanced oil recovery mechanisms and the conditions of unstable water in- jection. This article, based on the Shuanghe oilfield 437 1[ 1 - 2 fault block, uses reservoir engineering and numerical simulation method, studies the enhanced oil recovery mechanisms and finds applicable conditions of unstable water injection in super high water cut stage to provide the basis for field practices.
