Simulation of Thermal Power on Bottomhole on the Basis of Experimental Studies of Drilling Tool Operation

This work analyzes analytical dependences used for determination of power on bottomhole, the influence of negative temperatures on rock destruction tool is estimated. The experimental study of power on bottomhole is described including its influence on the temperature of borehole. On the basis of experimental results, the conclusion is made of strong correlation between power on bottomhole and volumetric rock destruction, mathematical model of this dependence has been developed. The proposed model can be applied for optimization of hole drilling modes.
