| Abstract: | This paper presents a theoretical analysis and experimental study on the flow properties of Power-law fluids in the annuli of directional wells. The physical model for annulus flow in directional wells is given. The formulae of velocity profile, flow rate and pressure loss for axial laminar flow of Power-law fluids are developed. The analysis stand for simulating directional well annulus has been designed and set up. Also included in this paper are the measurements of velocity profile and pressure loss for axial laminar flow of Non-Newtonian polyacrylatnide solutions taken from the simulating stand. The transitional properties of flow regions, the turbulent flow pressure loss and the effect of rotating inner pipe on the flow properties of Power-law fluids are experimentally studied. |
