摘要: 中国页岩气勘探开发历经10余年的坚持不懈探索,初步实现了技术迭代与逐年上产,但要实现规模效益开发仍面临相关科学与技术瓶颈。为了进一步推动页岩气效益开发,实现“中国页岩气革命”,通过川南地区与美国页岩气地质特征及开发方式等差异对比分析,明确中国页岩气未来发展方向。研究表明:(1)川南页岩气藏受多期构造运动叠加影响,具有构造复杂、应力差异大、储层非均质性强的特点,尽管其有机质丰度(TOC)与成熟度(Ro)具备优势,但孔隙度、渗透率、单井控制储量等关键参数显著低于美国典型页岩气田,导致规模效益开发面临天然瓶颈;(2)美国成熟的“水平井+体积压裂”技术体系虽具借鉴价值,却难以直接复制,中国必须立足复杂地质条件,突破甜点精准刻画、超长水平井钻井、高效压裂工艺等技术瓶颈,构建适配本土地质工程条件的技术体系;(3)美国页岩革命的成功核心在于项目制管理与日费制合同机制,实现了高风险条件下的高效迭代,反观中国传统的“接力棒”管理模式,严重制约开发效率,亟须推行扁平化项目制改革激发管理效能。近年来川南地区页岩气勘探开发实践表明开展“中国页岩气革命”是实现高质量发展的必由之路,需建立一套适配中国页岩气高效组织的特色管理体系,走适合中国页岩气发展的创新道路,同时重点开展地质工程甜点精细刻画、工艺技术迭代与立体开发实验,才能奋力实现中国页岩气产业发展的二次跨越。

Abstract: After over a decade of persistent efforts, preliminary technological iteration and sustained production growth have been obtained in shale gas exploration and development in China. However, it still faces scientific and technological challenges in realizing the large-scale and beneficial development. In order to advance the beneficial shale gas development and achieve “China’s Shale Gas Revolution”,  comparative analysis of shale gas geological characteristics and development methods between Southern Sichuan Basin and the United States has been conducted, and future development direction of shale gas in China has been clarified. The study results indicate: (1) Affected by multi-stage tectonic events, shale gas reservoirs in Southern Sichuan Basin are characterized by complex structure, great stress difference, and high reservoir heterogeneity. Despite its superior organic matter abundance (TOC) and maturity, critical parameters including porosity, permeability, and single-well controlled reserves are poorer than those in typical U.S. shale gas fields, posing inherent constraints to the large-scale and beneficial gas development. (2) Although the U.S. “horizontal drilling + volume fracturing” system offers valuable references, it is infeasible for direct replication. In response to the complex geological conditions in China, oil companies should overcome technical barriers in sweet spot delineation, ultra-long horizontal well drilling, and high-efficiency fracturing technology, and construct a technological system adapted to the native geological and engineering conditions. (3) The core factor for successful shale revolution in the U.S. lies in project-based management and day-rate contracting system, which achieves high-efficiency iteration given the high-risk conditions. In contrast, China’s traditional “relay-style” management mode severely impedes operational efficiency, so it is urgent to promote the flattened project system reform to stimulate management efficiency. Recent field practices in Southern Sichuan Basin show that the “China’s Shale Gas Revolution” is imperative for high-quality development, which demands establishing a tailored management system with operational autonomy, pursuing innovation aligned with China’s geological realities, and prioritizing geological–engineering sweet spot characterization, technological iteration, and stereoscopic development pilots to achieve a second leap in the development of shale gas industry in China.
