摘要
低渗透油藏所占比例越来越大,为了提高低渗透油藏原油采收率,综述了目前广泛研究的注气驱,分别介绍了CO_2驱,N_2驱,烟道气驱和天然气驱的驱油机理,分析了目前的研究现状,并指出了研究中所遇到的问题。
Low permeability reservoir the proportion is increasing, in order to improve the crude oil recovery in low permeability reservoir, this paper discusses the widely studied gas injection flooding, introduces CO2 flooding, Nz flooding, flooding mechanism of flue gas flooding and gas drive, analyzes the current situation of the research, and points out the problem in the study.
