Study of Drilling Fluid Behavior in the String During Drilling

Abstract

This study investigates the steady, turbulent, forced flow of an incompressible non-Newtonian fluid (Bingham or pseudoplastic Power-law) in an isothermal cylindrical pipe. The finite volume method is adopted to solve the energy balance using ANSYS FLUENT. The objective of this work is to analyze the hydrodynamic and thermal behavior of the drilling fluid as it circulates through the drill string. The results reveal an interaction between drill string rotation, flow rate, the rheological nature of the drilling fluid, and other boundary conditions.
