| Abstract: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. |
