摘要:

在简述朱溪矿区ZK5407孔前期钻探施工的基本情况后，根据定向纠斜地质要求等情况确定了纠斜总体思路。详细介绍了自孔深1288.70 m、顶角8.6°、方位角30°至孔深1637.25 m、顶角2.7°、方位角257°共17次的包括螺杆定向纠斜的理论准备、设备仪器、实施经过和钻进工艺在内的螺杆定向纠斜施工工艺，并阐述了开创江西省地矿系统深孔螺杆定向钻探先例之成果意义。

Abstract:

Based on the previous construction situation of ZK5407 in Zhuxi mining area and according to the geological requirements of directional deviation correction, the general idea of directional deviation correction was determined. This paper introduces in detail the screw directional deviation correction technologies used 17 times in the segment from the hole depth of 1288.70m, angle 8.6 and azimuth 30 to the hole depth of 1637.25m, angle 2.7 and azimuth 257 , including the theoretical preparation, instrument and equipment, implementation process and drilling technology.
