利用注水井测试资料识别油层高渗透带

对于已进入高含水后期的水驱油田而言,控水是延长油田有效开发期,提高油田寿命的必由之路,而高含水后期水驱控水重点是针对导致注入水低效无效循环的高渗透带,因此必须开展高渗透带的识别,进而使水驱控水措施有的放矢,为高含水后期的水驱控水提供技术支撑。本文从高渗透带的基本特征出发,应用其在测井资料上的鲜明特征结合动静态等资料加以识别,并开展了应用,其效果表明应用测井资料识别高渗透带油层是可行的。

To Identify Zones of High Permeability in a Reservoir Using Testing Data of the Injector

As to a water flood field of high water-cut, water control is the only way to prolong the development period and oilfield life.The emphases of water control is the high permeability zones which will cause low-efficiency water injection and futile cycle.So the high permeability zones must be identified so that waterflood control measures have a definite object.It will provide technology support for waterflood at later stage of high water-cut.This paper describes how to identify high permeability zones according to the characteristics of them with well logging data and dynamic and static data. It was carried out into practice. The result shows that it is feasible.
