摘要
CO2驱油技术是指把CO2注入地层,利用CO2自身特性驱替原油到采油井的工艺.文章分析了 CO2驱油机理,总结了 CO2注入方式的优缺点、提高采收率的基本原理、设备防腐的措施、降低最小混相压力的方法,指出了 CO2驱油技术面临的设备腐蚀严重、难以混相等问题及今后发展的方向.
Abstract
CO2 flooding technology refers to the process of injecting CO2 into the formation and using CO2's own characteristics to displace crude oil to oil production wells.This paper analyzes the mechanism of CO2 flooding,summarizes the advantages and disadvantages of CO2 injection methods,the basic principles of enhanced oil recovery,the measures of equipment anti-corrosion,and the methods of reducing the minimum miscible pressure,and points out the problems of serious equipment corrosion and difficult mixing of CO2 flooding technology and the direction of future development.
