Different from polycrystalline diamond compact drill bits (ie, PDC bits) ,cone bit is harder to design more balanced state, because of its geometric space limitations, rolling cone and its many design variables. To overcome this difficulty, foreign researchers have developed optimization techniques, making the cone bit to get the balance of the first evaluation, followed by its volume and pressure has been re-balanced. The volume of the cone is a balanced equilibrium between the amounts of debris removal, the balance of the pressure roller is able to ensure suffered WOB, bending moment and bearing pressure is almost the same. Thus, there is nothing a cone or bearing system generates excessive force situation.

When all rollers and the bearing are under the same pressure, the cutting structure achieved a pressure balanced condition. During the drilling cuttings discharged when all cutters the same amount, the cutting structure to achieve a volume balance condition. Energy balance (EB) refers to both the drill reached a pressure balance', also reached a volume balance. Energy balance cone bit has the advantage that by balancing the amount of rock drilled by the force of each roller, to improve cone rock bit cutting structure and the dynamic state of the interface. Laboratory and field tests show that the energy balance of the down hole drill bit of the smoother, Tricone bit and the impact forces suffered the smallest drill, thus improving the cutting ability of the bit. Smooth, low vibration directional drilling also helps improve response, reduce the risk of fatigue failure palm teeth and damage sensitive components drill string.
