摘　　要：2013年9月国家能源局批准设立了“重庆涪陵国家级页岩气示范区”(以下简称示范区),示范区于2015年12月建成,经过近10年的开发已成为国内页岩气产量的主要阵地。为加快我国页岩气理论认识与勘探开发技术集成和突破,有效推动中国海相页岩气的大发展,在对示范区发展建设历程、地质理论认识、工程工艺技术、关键装备进展等内容进行系统地梳理、总结和回顾的基础上,展望了示范区未来的发展方向。研究结果表明:(1)示范区页岩气勘探开发经历了勘探评价、一、二期建设、立体开发调整三个阶段;(2)创新建立了海相页岩气“二元富集”理论和高效开发气藏工程理论认识;(3)创新形成了页岩气丛式水平井优快钻井技术、差异化缝网压裂技术、高效采气集输技术、岩溶山地绿色开发技术等配套技术体系,实现了关键装备和工具国产化;(4)实现了示范区埋深3 500 m以浅超压页岩气藏高效开发,埋深3500~4000m页岩气藏有效开发;(5)示范区未来建设主要包括加快推进深层、常压页岩气发展、持续攻关页岩气提高采收率技术、积极推广新技术新方法现场应用、着力强化绿色示范区建设等方面。结论认为,该示范区是4个国家级页岩气示范区中最早建成的,示范区取得的成果将继续指导中国页岩气勘探开发,对推动我国页岩气地质理论和勘探开发技术发展具有示范和指导作用。In September 2013, the National Energy Administration approved the establishment of "Fuling national shale gas demonstration area"(hereinafter referred to as the demonstration area), whose construction was completed in December 2015. After nearly one decade of development, it has grown into the main shale gas production base in China. In order to speed up the integration and breakthrough of China’s shale gas theoretical understanding and exploration and development technology and effectively promote the great development of marine shale gas in China, this paper reviews and summarizes the development and construction history of the demonstration area,geological theory understanding, engineering technology and key equipment progress. And based on this, the future development direction of the demonstration area is predicted. And the following research results are obtained. First, shale gas exploration and development in the demonstration area is divided into three stages, i.e., exploration evaluation, phase I and II construction, and three-dimensional development adjustment. Second, the "binary enrichment" theory of marine shale gas and the engineering theory of efficient gas reservoir development are innovatively established. Third, a series of supporting technologies are innovatively developed, such as optimized and fast drilling technology for shale gas cluster horizontal wells, differentiated network fracturing technology, high-efficiency gas production, gathering and transportation technology, and green development technology for karst mountains, and the localization of key equipment and tools is realized. Fourth, the efficient development of shallow overpressure shale gas reservoirs above 3 500 m in depth and the effective development of shale gas reservoirs at the depth of 3 500 – 4 000 m are realized in the demonstration area. Fifth, the construction of the demonstration area in the future includes accelerating the development of normal-pressure deep shale gas, continuously tackling key shale gas EOR tec
