Construction Technology of Screw Directional Deviation Correction for Deep ZK5407 in Zhuxi Mining Area of Jiangxi

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.
