摘　　要：俄罗斯是世界油气资源最丰富的地区之一,2009年,俄罗斯石油产量为4.94×108t,天然气产量为5560×108m3,高居世界榜首。前苏联及俄罗斯非常重视提高采收率(EOR)问题,早在20世纪70年代,提高采收率技术就已成为油气开采的热点,研发运用了包括热法、气法、流体转向技术等多种EOR技术。另外,EOR技术对俄罗斯国家石油产量的贡献也非常突出,2006年,俄罗斯EOR技术贡献产量达(17～18)×106t。俄罗斯EOR技术分类与世界通用分类存在一定差别,水动力学法、侧钻水平井等所有增产措施都纳入到EOR技术范畴。回顾了前苏联和俄罗斯提高采收率发展历史,分析俄罗斯EOR技术与世界通用分类之间的差异,总结近30年来俄罗斯EOR技术的发展现状,并对流体转向技术、气驱、热采、水动力学方法、微生物EOR和非常规EOR等技术应用情况进行总结与评述。Russia is one of the regions with the richest petroleum resources in the world.In 2009,oil production had reached 4.94×108t,and natural gas production was 5560×108m3 in Russia,the highest production in the world.Former Soviet Union and Russia have paid more attention to enhance oil recovery(EOR),and many EOR technologies,such as thermal recovery,gas drive,flow diverting technologies(FDT),etc,have been researched and put into use in oilfield since 1970s.EOR had a great contribution to oil production in Russia,the oil production in Russia based on EOR implementation can be estimated as(17-18)×106t in 2006.Russian EOR classification has some differences from the system recognized all over the world,hydrodynamic techniques and side tracks and some other stimulations are all regarded as EOR.This paper reviewed the EOR history and summed up the development status during the past 30 years of former Soviet Union and Russia,particularly,discussed FDT,gas drive,thermal recovery,hydrodynamic techniques,microbiological EOR and unconventional EOR.
