      Torque reduction sub is a new type of torque reducing tool, It is mainly connected between short radius horizontal section and large angle well section, propose to connect a torque reduction sub by every 60ft, it can reduce 25-35% torque after using this tool, it’s slip spiral inner sleeve, straight rib outer sleeve and body mandrel are relatively in non-rotating condition. An isolation point supported by the straight rib outer sleeve can be formed between the drill pipe and the casing, which can reduce the torque of the rotary table; It can effectively prevent the direct contact between the drill pipe and the casing, reduce the wear of the drill pipe and the casing, and protect the casing; Reduce the frictional contact force between the drill pipe and the casing, and reduce the resistance of the drill. Greatly improve the service life of drill Pipe.
