水井调剖、调驱措施是裂缝型油藏开发中后期改善注水开发效果的重要手段之一。注水井调剖,油井堵水的效果评价,不仅应从单井注采状况考虑,最终应归结到产油层的利用程度,注入水的波及系数、注水开发油藏的阶段采出程度、注水开发效果和注水采收率等几个方面。本文着重讨论了深部调剖、调驱的评价方法,为调剖堵水改善水驱效果提供理论依据。
Water well profile control and drive control measures are one of the important measures to improve the effect of waterflood development in the middle and later stages of the development of fractured reservoirs. Water injection well profile control, the effect of well water shutoff evaluation, not only should be considered from single well injection and production conditions, and ultimately should be attributed to the production level of oil production, water injection coefficient, water injection reservoir development stage, water injection development effect And water injection recovery and other aspects. This article focuses on the evaluation of deep profile control and flood control, which provides a theoretical basis for controlling the effect of waterflooding by water control.
