摘　　要：气井产水量的不断增加对天然气生产构成严重威胁,其影响越来越受到人们的关注和重视。使用井下气液分离及回注技术,可以降低举升和处理费用,增加生产寿命,提高采收率,减少环境污染,简化地面分离设备,提高投资效益。针对井下分离及回注技术研究现状进行了分析,给出了井下气液分离及回注形式、适用条件和技术设计、应用方面的结论。People raise more and more concern about ever increasing water production, a terrible threat to gas production. Applying the technology of downhole gas/water separation and reinjec-tion can reduce lifting and disposal costs, increase production life and rates, diminish environmen-tal pollution, eliminate surface handling of water, and increase investments profit. In this article, we generally analyze the technology downhole gas/water separation and reinjection; give the con-crete style and applied situation, and some useful conclusions in technology design and applica-tion.
