API water oil gas drilling tricone bits TCI rock bits
Tricone bit is an important tool for oil drilling, its work performance will directly affect the quality of drilling, drilling efficiency and drilling costs
1. Working principle
The cone bit is crushed and eaten into the rock under the action of the bitter and drill string rotation, and produces a certain slip to shear the rock.When the cone rolls in the bottom of the hole, the teeth on the cone in turn impact, into the formation, this effect can be part of the bottom of the rock crushed, while the sliding action caused by the rotation of the teeth cut off the remaining teeth between the remaining Part of the rock, so that the bottom of the rock completely broken, the hole can be extended.
2. Product advantages
Oil drilling and geological drilling is the most used or cone bit.The cone bit has the effect of rocking, crushing and shearing the formation rock in rotation, so the cone bit can be adapted to soft, medium and hard layers.Especially in the jet cone bit and long nozzle after the emergence of cone bit, the cone drill bit drilling speed greatly improved, is the history of the development of cone bit a major revolution.The cone bit can be divided into teeth (tooth) by tooth type, tooth (bit) (tooth set inlaid with carbide teeth) cone bit;According to the number of teeth can be divided into single cone, double , Three-cone and multi-cone bit.At home and abroad use the most, the most common is the three cone bit.
