摘　　要：近年来,完井工艺技术的发展使得致密油资源实现了商业开发,但致密油藏的原油采收率仍处于较低水平,有必要对致密油提高原油采收率(EOR)技术进行研究。本文在概述国内外致密油资源研究开发现状的基础上,总结了三种研究、应用较为广泛的提高原油采收率技术:注气开发、注水开发、渗吸驱油,并对比了各技术的优缺点,以期为提高致密油资源采收率提供借鉴。In recent years,the development of well completion technology has enabled the commercial development of tight oil resources,but the crude oil recovery of tight reservoirs is still at a low level.So enhanced oil recovery(EOR)in such reservoirs is very important and necessary.This paper briefly summarized the present situation of exploration and development of tight oil,reviewed three of the most widely studied EOR technologies,gas injection,water injection,imbibition displacement,and illustrated their limits of application in detail.It is expected to provide reference for enhancing the recovery of tight oil resources.
