Flow Analysis and Approximate Expressions of Factors Related to Frictional Loss for Laminar Flow of Viscoplastic Fluids through a Concentric Annulus

The mud flow between the borehole and the drill pipe in well drilling can be regarded as the flow of nonNewtonian fluids through a concentric annulus. In recent years, the Herschel-Bulkley rheological model is recommended as a general fluid model of drilling mud because it encompasses the power law...
