摘要
我国煤层气资源量极为丰富 ,居世界第三位。其中陆上埋深 2 0 0 0m以浅的煤层气资源量达 30×1 0 1 2 ～ 35× 1 0 1 2 m3,2 0 0 0m以深的煤层气资源量达 67× 1 0 1 2 m3。目前中国煤层气产业面临着形成和发展的历史机遇 ,主要表现在 :①在洁净能源和环保的双重要求下 ,我国政府重视煤层气开发利用 ,优惠政策纷纷出台 ;②中国煤层气开发利用 ,已成为世界煤层气工业关注的焦点 ;③国内煤层气自营勘探轰轰烈烈 ,成效显著 ;④全国煤层气规范管理正步入正轨。目前中国煤层气产业发展面临的挑战及应采取的对策是 :①我国输气管网基本建设相当薄弱 ,煤层气长输管网应纳入国家中、长期发展规划 ;②我国虽然基本掌握煤层气开发的主要工程技术 ,但远不够完善 ,对其核心技术应在政府有关部门大力支持下组织协同攻关 ;③中国缺乏寻找煤层气高渗富集区的有效方法和手段 ,增加了勘探风险 ,应尽快启动系统研究工程 ;④中国煤层气赋存条件与美国有较大差别 ,建议国家有关部委应尽快启动低、高阶煤煤层气基础理论研究 ;⑤建议国家给予更加优惠的煤层气政策。
China is very rich in coal-bed gas resources,occupying third place in the world,in which the coal-bed gas resource extent above 2 000 m(buried depth)is 30×10 12 ～35×10 12 m 3 and that below 2 000 m(buried depth)is 67×10 12 m 3 in the land.At present the historical opportunity faced by forming and developing the coal-bed gas industry in China is mainly shown as follows:①according to the requirements of both clean energy resources and environmental protection the government departments in China have attached great importance to the development and utilization of coal-bed gas and a series of preferential policies are making up one after another;②the development and utilization of coal-bed gas in China have become the focal point concerned by the world coal-bed gas industry;③the self-operating exploration for coal-bed gas in China is vigorously carrying out with significant achievements;and ④ the standardized management of coal-bed gas in China has been led onto the correct path.At present the competitions faced by developing the coal-bed gas industry in China and the countermeasures which should be adopted are:①the capital construction of gas line network in China is very weak and the long-distance transmission pipeline network of coak-bed gas should be brought into the state middle- and long-term development planning;②although the marjor engineering of developing coal-bed gas has been basically grasped in China,it is far inferior to perfection and its key techniques should be overcome in coordination under the support and organization by relevant government departments;③certainly,the exploration risk inicreases for lack of the effective methods and means to survey high-permeability accumulation regions in China,so that a systematic research work should be carried out as quickly as possible;④because the occurrence condition of coal-bed gas in China is much different from that in U.S.A.,it is suggested that relevant ministries and commissions should organize the basically theoretical research on the coal-bed gas of low- and high-rank coals as quickly as possible;and ⑤it is suggested that relevant government departments should give the development and utilization of coal-bed gas much more preferential policies.
