碳减排背景下难采稠油提质增效研究进展OA
Research progress of quality improvement and efficiency enhancement of difficult-to-recover heavy oil reservoirs in context of carbon emission reduction
中国稠油资源总量比较丰富,开发方式以高能耗、高排放的热采技术为主,年排放CO2量超过1 600×104 t.而随着"双碳"目标的提出,中国稠油资源开发的提质增效与节能减排成为能源领域的研究热点之一.梳理了4种常规热采技术的应用现状,其中占据主导地位的蒸汽吞吐已处于开发后期亟需转换开发方式,蒸汽驱、SAGD和火驱技术尚且存在诸多问题,影响其推广应用.分析了"双碳"背景下包括非凝析气体辅助蒸汽热采增效技术、化学辅助蒸汽热采增效技术、驱泄复合强化热采技术、稠油原位催化改质水热裂解技术、低渗透稠油油藏注CO2压裂吞吐开发以及普通稠油气体-化学复合冷采技术在内的6种新型稠油提质增效开发技术现状,着重描述其提高采收率机理以及研究应用情况,并综合中外经验和开发状况,提出未来的攻关方向与发展趋势.研究认为,"双碳"背景下,需要依靠提高全环节效率,优化油田能耗结构,大力发展低碳热采技术,推动热采工艺向冷采工艺过渡,大力发展高效冷采技术等,实现难采稠油的提质增效与节能减排.
The heavy oil resources is relatively rich in China,and the development mode is mainly thermal recovery with high energy consumption and high emissions,which emits more than 1 600×104 tons of CO2 annually.With the proposal of carbon peaking and carbon neutrality goals,the quality improvement and efficiency enhancement of heavy oil resources development,as well as energy saving and emission reduction,have become one of the research hotspots in the energy field in China.In this paper,the application status of four conventional thermal recovery technologies was reviewed,in which the dominant steam huff and puff has been in the late stage of development and needs to be converted in terms of the development mode;the steam drive,SAGD,and fire drive technologies still have a lot of problems,which affects the promotion and application of these technologies.Under the background of carbon peaking and carbon neutrality,non-condensate gas-assisted steam thermal recovery and efficiency enhancement technologies,chemical-assisted steam thermal recovery and efficiency enhancement technologies,drive-drain composite enhancement thermal recovery technologies,in-situ catalytic reforming hydrothermal cracking technology for heavy oil reservoirs,CO2 fracturing and huff and puff mining for low-permeability heavy oil reservoirs,and gas-chemistry composite cold recovery technologies for ordinary heavy oil reservoirs were analyzed.The recovery enhancement mechanism and research application were described,and by synthesizing Chinese and international experience and development status,the study proposed the future direction and development trend of the research and development.The study concludes that under the carbon peaking and carbon neutrality,it is necessary to improve the efficiency of the whole process,optimize the energy consumption structure of oilfields,vigorously develop low-carbon thermal recovery technology,promote the transition from thermal to cold recovery process,and vigorously develop high-efficiency cold recovery technology and other technologies and means,so as to realize the quality improvement and efficiency enhancement of difficult-to-recover heavy oil reservoirs,as well as energy saving and emission reduction.
