Torque reduction sub is to reduce the excessive torque generated by drilling in short radius horizontal section and large angle well section. According to its structural components, the torque reduction sub is divided into: mandrel body, upper and lower sliding bearings, slip spiral inner sleeve, straight rib outer sleeve, stop collar etc.
Torque reduction sub is mainly connected between short radius horizontal section and large angle well section, propose to connect a torque reduction sub by every *0ft, it can reduce *5%**5% torque after using this tool, its slip spiral inner sleeve, straight rib outer sleeve and body mandrel are relatively in non-rotating condition.
Advantages
1. 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;
2. 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;
3. Reduce the frictional contact force between the drill pipe and
the casing, and reduce the resistance of the
drill;
4. Greatly improve the service life of drill Pipe.
