摘要
本文详细阐述了全球尤其是北美页岩气开发现状,论述了Marcellus与Haynesville页岩气区的主要特征,认为持续技术创新、高效经营管理模式、多元产业扶持政策是美国页岩气飞速发展的主要驱动力,对我国页岩气的开发具有良好的借鉴作用。作者系统梳理了中国页岩气近20年的探索攻关与实践历程,认为历经评层选区、开发试验、示范区建设、海相页岩气规模开发4个阶段,国内页岩气开发取得了重大成就,建成川南、涪陵等中深层页岩气大气田,实现了海相页岩气规模效益开发,2022年产量达238亿方,成为我国天然气重要的供应来源,同时深层页岩气产能建设稳步推进,新区新层系勘探也取得重大突破。在深入分析我国页岩气地质与资源特征的基础上,文章论证了我国具备年产500亿~800亿的开发潜力,但需要从完善页岩气立体开发配套技术、持续优化页岩气地球物理评价技术、加快钻井与压裂工程技术迭代升级、加大新层系新领域的勘探评价力度4个方面持续攻关。
The paper firstly analyzes the current status of worldwide shale gas development.The status of North America shale gas development and main characteristics of the Marcellus and Haynesville shale gas areas are analyzed in detail.It is believed that continuous technological innovation,efficient management models,and diversified industry support policies have been the main driving forces for the rapid development of shale gas in the United States,which is a valuable experience for the development of shale gas in China.Secondly,the paper systematically reviewed the exploration and development of shale gas in China over the past 20 years.It is believed that China shale gas had made significant achievements with four stages development:the evaluation stage,the in-situ development experiments stage,the demonstration area construction stage and the large-scale development of marine shale gas stage.China has developed several shale gas fields including Southern Sichuan and Fuling.Also,the marine shale gas has achieved large-scale and cost-effective development with the production reaching 23.8 billion cubic meters in 2022,and has become an important part of China natural gas supply.Meanwhile,the deep shale gas development is steadily advancing,the new formation and new area of shale gas exploration has made significant breakthroughs.Lastly,based on the analysis of the geological characteristics of shale gas in China,the paper proposed that China’s annual shale gas production could reach 50 billion to 80 billion cubic meters per annum in the near future.However,it is necessary to continue work on four issues:improving the shale gas three-dimensional development technology,optimizing shale gas geophysical evaluation technology,upgrading shale gas drilling and fracturing technology,and exploring new shale gas formations and areas.
