-
摘要: 我国具有丰富的致密油资源,但目前整体上开发规模仍然较小,油藏认识和工程技术处于发展阶段。在介绍致密油藏特征及中国石化致密油开发概况的基础上,分析了致密油开发面临的主要问题及发展机遇,指出地质条件复杂、开发技术需要进一步发展以及在低油价下如何实现致密油的效益开发是我国致密油开发面临的主要挑战,并给出了我国致密油开发技术的5个发展方向,即富集规律研究、开发机理研究、进一步发展致密油开发工程技术、加强致密油藏提高采收率技术攻关、创建致密油开发模式和管理模式等。这对于实现我国致密油规模效益开发,保障国家能源供应和能源安全,具有一定的指导意义。Abstract: Tight oil resources are abundant in China, but they are only developed in small scale presently, understanding of the reservoir and engineering technologies are still at initial stage of development. On the basis of introducing the characteristics of tight oil reservoirs and Sinopec’s current development, the major challenges and opportunities for development of tight oil reservoirs were analyzed. It is indicated that main challenges in developing tight oil reservoir include complex geologic conditions, development technologies need to be improved, and the ways to develop tight oil reservoirs efficiently under the situation of low oil prices. Moreover, it is proposed in five aspects for developing tight oil reservoir in China, i.e. (1) identifying enrichment laws, (2) analyzing development mechanism, (3) further exploring the engineering technologies, (4) making more efforts in EOR technologies, and (5) establishing development and management modes, which will play an important part for efficient development of tight oil reservoirs, and keep national energy supply and security in China.
