摘要
针对中国海上天然气资源丰富与低渗储量逐年增加的情况,对海上油田注气提高采收率的潜力进行了分析。在分析、总结国内外海上油田注气项目的实施情况与特点的基础上,归纳了海上油田注气提高采收率的必要性、优缺点及关键技术,并阐述了对中国海上油田注气技术发展的启示;同时对海上油田注CO_2提高采收率与埋存的前景进行了展望。该研究对中国海上天然气资源的高效利用、低渗油藏提高采收率及温室气体埋存等研究具有现实意义。
In view of this situation that offshore natural gas resources are rich in China and low permeability reserves increase year by year,analyzed are application and characteristics of offshore Oilfield gas flooding projects,generalized are necessity and key techniques through actual cases and expounded is the enlightenment of offshore oilfield gas flooding development.Expected is the prospect of offshore oilfield gas flooding for oil recovery enhancement and CO_2 storage,which has practical significance in efficient development of tight reservoirs and reducing greenhouse gas emission in offshore field development.
