In the drilling process of a diamond drill bit, to a certain extent, the drill bit is the main tool for crushing the rock. During the production process, the wellbore is formed by breaking the rock with a drill bit, and a wellbore of the diamond drill bit is formed well. The length of time used, in addition to the properties of the rock being drilled and the performance of the drill itself, is related to the degree of mutual match between the drill bit and the formation.
The reasonable selection of diamond drill bits plays an important role in improving the drilling speed and reducing the overall drilling cost to a certain extent. Diamond drill bit is, to some extent, one of the important tools for oil drilling, whether the drill bit adapts to the nature of the rock and The quality of the product plays a very important role in the selection of the drilling process, especially in terms of drilling quality, drilling speed, and drilling costs.
In order to control the inclination of the well, diamond drill bits often adopt light pressure lifting measures to reduce the drilling speed. The formation pressure system is complex, and the pressure from the negative pressure to the abnormal high pressure is intertwined with the pressure system in the longitudinal direction. Sexual and lateral pressure systems are relatively independent.
The diamond drill bit breaks the rock through its own cutting teeth during operation. During operation, the drilling fluid channel is the drill bit's water eye. During the oil drilling work, the transverse shear during the drilling process is used. With the action of shearing and longitudinal vibration, the cone bit will achieve the purpose of crushing the rock, which can increase the drilling speed.
