📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではCBM開発は限定的だが、メタン漏出抑制は温暖化対策上有効。中国の技術進展は、LNG輸入国である日本にとって供給源多様化の観点から注視すべき。
In the global GX context
Globally, CBM technology reduces methane emissions from coal mining, supporting climate goals. China's deep coal rock gas breakthroughs offer lessons for other countries with similar geological conditions.
👥 読者別の含意

🏢実務担当者:Offers insights on technology selection for CBM projects in high-rank, low-permeability reservoirs.
🏛政策担当者:Highlights the need for policy support to advance CBM as a low-carbon energy source.
📄 Abstract（原文）
Coalbed methane (CBM) possesses the triple attributes of being an energy source, a greenhouse gas, and a mine disaster gas, making it a critical target for increasing reserves and production of unconventional natural gas, as well as for coal mine safety governance. This paper systematically reviews the current status of CBM development technologies in the United States, Australia, Canada, and China through literature review and case analysis. It focuses on comparing the technological path differences among these countries in terms of resource endowment, well type selection, reservoir stimulation, and drainage systems. Research indicates that North America and Australia have formed mature models centered on vertical wells or multi-seam co-production, primarily targeting shallow, medium-to-low rank, and high-permeability coal seams. Under the conditions of high-rank, low-permeability, and deep-buried coal seams, China has developed characteristic technologies such as "geology-engineering integration," horizontal well volume fracturing, and full life-cycle drainage, achieving breakthroughs in the medium-shallow high-rank coals of the Qinshui Basin and the deep coal rock gas of the Ordos Basin. Future efforts should continuously focus on sweet spot evaluation and construction, deep fracturing and intelligent drainage, green and low-carbon development, and policy synergy to enhance the safety, economic viability, and strategic support capacity of the CBM industry.
