Working theory of TCI tricone bit
Tricone bit is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air.
INTERRELATIONSHIP BETWEEN INSERTS REQUIREMENTS AND THE FORMATION
Formation Characteristics | Insert Spacing | Insert Properties | Penetration and Cuttings Production | Cleaning Flow Rate Requirement |
| Soft | Wide | Long and sharp | High | High |
| Medium | Relatively wide | Shorter and stubbier | Relatively high | Relatively high |
| Hard | Close | Short and rounded | Relatively low | Relatively lower |
