1. The function of the tricone bitThe top of the tricone bit adopts diamond compound teeth on the top of the cone to enhance the wear resistance of the teeth and increase the service life of the bit. ...

Diamond bit is a cutting tool which uses diamond material as cutting edgeThe mining drill bit is the main component of the drilling equipment, and its main function is to break the rock and form a bor...

PDC bit is made of polycrystalline diamond cutting blocks, and then a certain number of cutting blocks are mounted (or sintered) on the bit body.The cutting block is sintered into a whole by a thin la...

As a tool for drilling rock formations, rock bits have been widely used. Significant improvements in bit performance have directly reduced drilling costs, especially in the past decade. Service life a...

Water well drill bits can be regarded as the lowest cost drill bit, because we all know that water well drill bits are used in the upper stratum, and the wear on the drill bit is very small, so the ha...

Ⅰ. The common phenomenon of PDC drill bit balling　　1. The footage is obviously slower when drilling, or it is obviously higher when drilling;2. Increasing or reducing WOB has no obvious effect on d...

The main parameters of the rock reamer operation control are the push-pull force applied to the reamer by the drilling rig (pull force during reverse reaming, thrust force during forward reaming), or ...

Choosing the suitable under reamers hole openers according to the characteristics of the stratum during construction is the main way to improve construction efficiency.In order to adapt to different f...
