江西城门山矿区ZKJ4-10孔螺杆定向纠斜技术
|
摘要
江西省九江县城门山矿区补充勘查项目设计钻孔多为超斜孔,钻孔弯曲度要求高,施工难度大。该矿区多个钻孔都面临着纠斜的难题。本文结合矿区深孔ZKJ4-10孔定向纠斜实例,详细介绍了螺杆钻定向纠斜技术的工作原理、配套设备、操作方法及注意事项。通过矿区钻孔纠斜效果,总结了该技术的优点及不足,为今后地质深孔定向纠斜施工提供了借鉴。
In Chengmenshan mining area of Jiangxi Province,the most boreholes designed for the supplementary mining exploration project were ultra inclined with high requirement of drilling curvature,which made drilling construction difficult.There were difficulties of drilling straightening for many boreholes. Combining the instance of directional correction in deep hole ZKJ4-10,this paper introduces the working principles of screw directional correction of inclination,supporting equipments,operation methods and the points for attention. Based on the correction effects,the advantages and disadvantages of this technology are summed up,which provide reference to straightening construction in future deep geological holes drilling.
