The tri-cone bit is an important tool for oil drilling, and its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. Tri-cone bit designs are mostly based on practical experience, combined with the method of trial and error, and repeated design and calculation. We have more than 20 years of experience in supplying roller cone drills. The quality of our products is guaranteed.

According to the type of teeth, the roller cone bit can be divided into milling tooth (steel tooth) roller cone bit, insert tooth (tungsten carbide teeth are installed on the roller cone) roller cone bit; according to the number of roller cones, it can be divided into single roller cone bit, three tooth Rotary bit and assembled multi-cone bit. The most widely used at home and abroad is the tri-cone bit. We can provide all kinds of roller cone drills according to customers' requirements.

Working principle:

Under the action of drilling pressure and drill string rotation, the teeth of the roller cone bit are crushed and eaten into the rock, and at the same time, a certain amount of sliding is generated to shear the rock. When the cone rolls at the bottom of the well, the teeth on the cone impact and press into the formation in turn. This action can crush a part of the rock at the bottom of the well, and at the same time, the shearing action caused by the sliding of the cone cuts off the remaining remaining between the teeth. A part of the rock breaks the rock at the bottom of the well, and the wellbore can be extended.
