摘要
千米定向钻机是目前最先进的定向长钻孔施工设备,其应用将极大的提高防治瓦斯的技术装备水平。实际应用中,千米钻机在软煤层、构造区、瓦斯包等地段较难施工,针对发生顶钻、夹钻甚至发生堵孔、塌孔、喷孔等瓦斯动力现象。改进了千米钻机原有的防喷防突装置和封孔工艺,保障了施工人员的生命安全和成孔率。
The directional drilling dig is the most advanced construction equipment for long borehole and can improve the technical level of gas prevention. According to the difficult construction of directional drilling dig in the sections of soft coal seam,structural zone and gas- rich area,by improving the blowout preventer and sealing technology of drilling rig,the efficiency and safety of the construction was guaranteed.
