摘要
注水是油田提高产量及采收率的一种常规措施和采油方法，但注水也存在着地层伤害，如水敏、乳化等。针对吐哈油田的储集层地质特征和注水情况，在应用离心法将样品分两批离心不同时间的基础上，经扫描电镜分析、X—衍射分析、荧光显微镜鉴定、渗透率检测等手段，探讨了室内注水模拟实验中伊／蒙间层矿物对储集层产生的伤害，提出了注水中迁移的伊／蒙间层矿物的乳化液堵将对油田油层产生较大伤害的观点。
Waterflooding is a kind of conventional measure for improving production and recovery factor in an oilfield, but there exist some formation damages such as water sensitivity, emulsification, etc. In terms of geological features of reservoirs and waterflood condition in Turpan-Hami oilfield, laboratory waterflood simulation test is conductedin order to check damages of illite/montmorillonite interbeded minerals to the reservoirs by means of centrifugal technique, scanning electron microscope analysis, X-ray diffraction analysis, fluorescent microscope identification and permeability detections. This paper proposed an idea that emulsion block in migrated illite/montmorillinite interbeded minerals has greater damages to oil reservoirs during waterflooding.
