摘要/Abstract

摘要： 结合大吉深层煤岩气田勘探开发实践，系统梳理煤层（岩）气科学价值及战略定位的演变，明确深层煤岩气突破的战略意义，提出关键技术攻关方向。研究结果表明，煤炭共伴生天然气主体经历了“煤成气—浅层煤层气—深层煤岩气”3个阶段，深层煤岩气的突破确立了煤层（岩）气的独立资源地位，丰富了非常规天然气理论体系。深层煤岩气突破具有4重价值：（1）拓展了煤层气勘探深度，重塑非常规资源格局；（2）提出了“二元富集”模式，丰富非常规油气成藏理论认识；（3）构建了大规模体积压裂等核心工程技术体系，实现深层资源效益开发；（4）建成了全球首个深层煤岩气田，实现煤层（岩）气领跑。未来仍须攻关甜点评价与高效建产、高效钻井与体积压裂和精细采气与智能集输技术，构建低成本、智能化、绿色开发路径。深层煤岩气已成为我国非常规天然气新的战略接替资源，助力我国能源结构调整和双碳战略目标实现。

Abstract: Based on the exploration and development practice of Daji deep coal rock gas field, the scientific value and the evolution of strategic position of coal bed (rock) gas are systematically reviewed, the strategic significance of breakthroughs in deep coal rock gas is clarified, and key technological research directions are proposed. The study results indicate that the main theoretical system of coal associated natural gas has gone through three stages of “coal derived gas–shallow coalbed methane–deep coal rock gas”. The breakthrough of deep coal rock gas has established the independent position of coalbed (rock) gas resources and enriched the theoretical system of unconventional natural gas, which has values in four aspects: (1) The exploration depth of coalbed methane has been expanded and the pattern of unconventional resources has been reshaped; (2) The “binary enrichment” mode has been proposed, enriching the theoretical understanding of unconventional oil and gas reservoir accumulation; (3) The core engineering technology system has been constructed such as large-scale volume fracturing, achieving the beneficial development of deep resources; (4) The world’s first deep coal rock gas field has been built, achieving a leading position in coalbed (rock) gas. In the future, it is still necessary to conduct research on sweet spot evaluation and high-efficiency capacity construction, highefficiency drilling and volume fracturing, fine gas production, and intelligent gas gathering and transportation technologies, so as to build a low-cost, intelligent and green development path. The deep coal rock gas has become a new strategic replacement resource of unconventional natural gas in China, which helps to adjust energy structure and achieve the dual carbon strategic goals in China.
