摘要
CO_(2)驱油技术是指把CO_(2)注入地层,利用CO_(2)自身特性驱替原油到采油井的工艺。文章分析了CO_(2)驱油机理,总结了CO_(2)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CO_(2)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。
CO_(2)flooding technology refers to the process of injecting CO_(2)into the formation and using CO_(2)'s own characteristics to displace crude oil to oil production wells.This paper analyzes the mechanism of CO_(2)flooding,summarizes the advantages and disadvantages of CO_(2)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 CO_(2)flooding technology and the direction of future development.
