中国煤层气发展战略探讨——以中石油煤层气有限责任公司为例

A discussion on CBM development strategies in China based upon a case study of PetroChina Coalbed Methane Co., Ltd.

近年来我国煤层气产业增速放缓,为了促进产业发展,亟需围绕做大做强我国煤层气产业这一重大课题开展研究工作。为此,以中石油煤层气有限责任公司为例,系统研究和总结了该公司自2008年成立以来在鄂尔多斯盆地东缘煤层气产业基地建设、新疆地区煤层气勘探开发等方面取得的技术进展和成果,分析了我国煤层气产业发展面临的机遇与挑战。在此基础上,提出了有利于煤层气产业发展的5大主攻方向:①突出加快新疆地区中低煤阶煤层气战略接替规模突破;②持续攻关已开发区增产和提高采收率技术,大幅度提升开发效益;③强化深部煤层气及煤系地层天然气综合开发,提高资源综合利用率;④建立基于人工智能和大数据的煤层气田智能信息技术,提升煤层气田开发水平;⑤开展煤层气效益开发创新管理体系研究,为煤层气效益开发提供科学的制度保障。结论认为:①鄂尔多斯盆地东缘煤层气的规模开发为国家提供了宝贵的清洁能源,为煤矿安全生产、节能减排提供了新路径、做出了新贡献;②应持续推进管理创新和技术创新,突出加快在新疆地区建设我国第3个煤层气产业基地,促进我国煤层气产业加快发展。

In recent years,the growth rate of coalbed methane(CBM)industry in China has slowed down.In order to promote its development,it is in urgent need to do the researches focusing on enhancing domestic CBM industry.In this paper,PetroChina Coalbed Methane Co.Ltd.was taken as an example.Its technical progress and achievements in the construction of CBM industrial base in the Eastern margin of the Ordos Basin and the CBM exploration and development in Xinjiang since it was founded in 2008 were systematically studied and summarized.Then,the opportunities and challenges of domestic CBM industry in the process of its development were analyzed.Finally,five main study directions for accelerating the development of CBM industry were put forward.First,speed up the scale breakthrough of the strategic replacement of medium-and low-rank CBM resources in Xinjiang.Second,continuously research the technologies for increasing production and recovery factor of developed areas,so as to enhance the development benefits greatly.Third,strengthen the comprehensive development of deep CBM and coal measure gas,so as to improve the comprehensive utilization ratio of resources.Fourth,develop the intelligent information technology based on artificial intelligence and big data suitable for CBM fields,to improve the development level of CBM fields.Fifth,study the innovative management system of CBM benefit development,to provide a scientific institutional guarantee for the benefit development of CBM.It is concluded that the scale CBM development in the eastern margin of the Ordos Basin supplies the nation with precious clean energy and provides new ways and contributions for the safe production and energy saving&emission reduction of coal mines.In addition,it is recommended to continuously promote management innovation and technological innovation and speed up the construction of the third CBM industrial base in Xinjiang so as to accelerate the development of CBM industry in China.
