| 摘 要： | 根据河南省板厂矿区ZK1403孔前期钻探施工基本情况及定向纠斜地质要求确定了纠斜方案。从小直径螺杆定向纠斜的理论准备、设备仪器、施工过程以及钻进参数方面确定了有效的定向纠斜施工工艺，实现了自孔深958 m、顶角10°、方位角143°至孔深1100 m、顶角7°、方位角18°的成功纠斜。通过矿区纠斜效果，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借鉴。

| Abstract: | With analysis of the existing drilling information of Hole ZK1403 in Henan Banchang Mining Area, a deviation correction plan was determined according to the geological requirements of directional deviation correction. An effective directional deviation correction process with the slim hole mud motor was developed in terms of deviation correction drilling theory with the slim hole mud motor, drilling equipment, instruments, drilling procedure and drilling parameters. Successful deviation correction was achieved from the hole depth 958m, inclination 10° and azimuth 143° to the hole depth 1100m, inclination 7° and azimuth 18°. Based on the correction results in the mining area, both the advantages and disadvantages of the process were summarized, providing reference for deviation correction in deep geological hole drilling. |
