我国煤矿区钻进技术装备发展与应用

Development and application of drilling technique and equipment in coal mining area of China

基于"十一五"期间以来地面、井下钻进技术装备取得的代表性成果,总结了煤矿区煤层气(煤矿瓦斯)"时空一体化"高效开发模式;介绍了地面、井下钻进技术装备的最新发展现状,结合现场应用分析了地面远端对接井、井下大直径及超长定向孔配套钻进技术装备的特点与应用前景;最后针对煤矿区生产需求,进一步剖析了煤矿井下钻进施工面临的问题,提出煤矿区钻进技术装备发展方向,以期为煤矿区钻进技术装备的研发应用提供参考。

Based on representative achievements of both surface and underground drilling technique and equipment since＂11 th Five-Year Plan＂,new pattern of high-efficiency ＂spatial-temporal integration＂development of coalbed methane（ gas） in coal mining area is summarized. Then the latest development of both surface and underground drilling technique and equipment is introduced,followed by analysis of characteristics and application prospects of the matching drilling technique and equipment for ground remote butted wells,and underground directional borehole with large diameter and length,combined with field applications,Finally,in light of the production demand in coal mining area,the problem faced with underground drilling in coal mine is further analyzed,and corresponding development direction is put forward which is expected to provide a reference on the application of drilling technique and equipment in coal mining area.
