烟道气驱提高采收率技术发展现状

Status quo of EOR technology development based on flue gas flooding

在国际油价上涨、温室气体减排等因素影响下,使得烟道气驱得到了发展。介绍了气体驱替的发展历程及各种气体驱替的优缺点,重点介绍了烟道气驱的发展概况以及我国烟道气排放情况。论述了烟道气驱提高采收率的机理、烟道气处理技术以及在国内油田的实践情况。国内油田的矿场实践表明:烟道气驱可有效提高油藏的采收率,特别是对稠油油藏效果更好。

International oil price spike and greenhouse gas reduction have a great impact on the development of flue gas flooding.This paper introduces the development,the merits and defects of gas displacement,and the emission of flue gas in China.It mainly discusses the EOR mechanism based on flue gas flooding,the flue gas processing technology and its application in domestic oilfields.Application results show that recovery of oil reservoirs,especially of heavy oil reservoirs,can be effectively enhanced based on flue gas flooding.
