Optimization of Bit Hydraulic Horse Power for The Maximum Drilling Rate

This paper introduces a new method for calculation of the maximum obtainable bit horse power and jet impact force at all depths. In this method, unknown theoretical constants parameters are optimized with using nonlinear multivariable optimization methods in order to achieve maximum hydraulic power and jet impact force after defining proper objective functions and the linear and nonlinear constraints. The only data required for implementing this method are drilling flow rate, pump pressure and physical properties of bit. Bit hydraulic horse power and jet impact force are drown versus flow rate at all depths after optimization of the mentioned parameters.To validate the proposed approach we have used field simulations with using Hydraulic software. We have shown that there is a reasonable agreement between the result of hydraulic simulation and the prediction from the proposed approach.
