“煤层气(煤矿瓦斯)开发利用基础研究薄弱。现有煤层气勘探开发技术不能适应复杂地质条件,钻井、压裂等技术装备水平较低,低阶煤和高应力区煤层气开发等关键技术有待研发。煤与瓦斯突出机理仍未完全掌握,深部低透气性煤层瓦斯抽采关键技术装备水平亟待提升。”《煤层气(煤矿瓦斯)开发利用“十二五”规划》提出的技术关键,为煤层气发展提出了攻坚攻关课题。
“The basic research on the development and utilization of coalbed methane (coal gas) is weak. Existing coalbed methane exploration and development technologies cannot adapt to complex geological conditions, and the level of drilling and fracturing technologies and equipment is low, and low-rank coal and high-stress coalbed methane development are key. The technology needs to be developed. The coal and gas outburst mechanism is still not fully understood, and the level of key gas and gas extraction technology for deep-low permeability coal seams needs to be improved urgently.“The development of coal bed methane (coal gas) ”12th Five-Year Plan " proposed The key technology for the development of coal-bed methane has raised the key issues.
