辽宁煤层气资源赋存特征及开发利用

OCCURRENCE FEATURES AND EXPLOITATION OF CBM (COALBED METHANE) RESOURCE IN LIAONING PROVINCE

伴随全球性的能源紧缺及环境问题,煤层气开发利用将作为新能源产业支持辽宁产业结构调整,其对于寻找新能源、改善大气环境质量、煤矿安全生产、实现辽宁可持续发展战略都具有深远的意义。为此,依据辽宁省铁法、阜新等五个地区的煤炭、煤层气地质报告,分析了辽宁煤层气赋存特征、煤储层特征及区内煤层气资源状况,并对辽宁省主要煤田煤层气赋存特征及开发利用现状和开发潜力进行了研究评价,同时对辽宁省煤层气市场与煤层气开发效益进行了分析,进而提出了重点目标区和开发利用建议。结论指出:辽宁中部煤田煤矿区有较丰富的煤层气资源,应以多种方式进行开发(包括地面钻探、矿山井下抽放、利用报废矿井抽放等方法)。

Facing up with the global issues like being short of energy and seriously polluted environment, Liaoning province began to find out how to tap the resources like CBM and take full use of CBM, which have become meaningful works at present in Liaoning province to adjust its industry structure, search for new and alternative energy, improve the atmosphere quality, keep the running of coal mines safely, and complete its strategy on the sustainable development. According to geological reports on coals and CBM in Liaoning's five districts such as Tiefa, Fuxin, etc., this paper analyzed the concurrence of CBM, the features on coal beds, and CBM resource distribution within the districts in the whole province. It also studied on the behaviors of concurrence of CBM and its development status quo while evaluating the potentiality of developing CBM, its current market, and its economy analysis. It then put forward the key targets for CBM development and some suggestions on how to tap and utilize CBM. It is concluded from studies that there are abundant CBM resource in the central Liaoning province so many ways of exploitation should be adopted to excavate the CBM as much as possible, i. e. ground drilling and exploration, borehole drainage, and the abandoned drainage and so on.
