摘要
无线随钻测斜仪、Φ65螺杆钻具在大口径定向工程钻孔中配合使用,可精确控制钻孔轨迹,进行随钻定向钻探,成功实现定向钻进。这些技术结合使用在煤矿钻井技术中,可为该技术在同类地层中的使用,提供有益的经验。
Clinoretee of wireless while drilling can be closely used with Ф 165 helicoid hydraulic motor in construction of large diameter directional hole. It can precisely control the trail of drill hole. Moreover, the directional drilling and wireless while drilling can be done based on this technology. In this paper, these technologies can be combined together in coal mine drilling process. These techniques are perfect matched with each other in practice. The experience can do good to the drilling of coal geology in Ningxia Hui Nationality Autonomous Region under similar stratum.
