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。

Abstract: Waterflooding is a kind of conventional measure for improving production and recovery factor in an oil-field, but there exist some formation damages such as water sensitivity, emulsification, etc. In terms of geological fea-tures of reservoirs and waterflood condition in Turpan-Hami oilfield,laboratory waterflood simulation test is conducted in order to check damages of illite/montmorillonite interbeded minerals to the reservoirs by means of centrifugal tech-nique, scanning electron microscope analysis,X-ray diffraction analysis, fluorescent microscope identification and per-meability detections.This paper proposed an idea that emulsion block in migrated illite/montmorillinite interbededminerals has greater damages to oil reservoirs during waterflooding.
