Diameter difference is the primary factor we consider. Diameter difference refers to the difference between the diameter of drill pipe and the diameter of drill bit. As we all know, the diameter of drilling hole is caused by the diameter of drill bit. According to the requirements of drilling technology, the diameter of drill pipe should be smaller than that of drill bit. In the drilling process, it is beneficial to the discharge of cinder. Reasonable diameter difference can reduce the friction force of drill pipe.

It is known that the diameter of the hole is caused by the diameter of the drill bit. According to the requirements of the drilling process, horizontal drilling: drill pipe
The diameter of the drill bit should be smaller than the diameter of the drill bit, which is conducive to the discharge of cinder during the drilling process, and the reasonable diameter difference can be reduced.
Less drill pipe friction force.
