EQUATIONS DETERMINE FLOW STATES FOR YIELD-PSEUDOPLASTIC DRILLING FLUIDS

A new calculation method can determine the state of flow and pressure losses, for all ranges of flow, for a yield-pseudoplastic drilling or cementing fluid. This method can evaluate the flow regimes without considering the fluid density as a determinant parameter. The method uses parameters related to fluid rheology, average flow velocity, and the geometry of the hydraulic circuit for conventional drilling and cementing conditions. Data from circulation tests in a well in Southern Italy have correlated well with calculated data using these equations.
