Viscosity Conversion of Viscometer Viscosity to Macroscopic Flow Viscosity of Non-Newtonian Fluid

Abstract In porous media, fluid flows through mesh structure made up of micro-braided capillary. Its flow state is similar to the flow in capillary. For Non-Newtonian fluid, we considered viscosity changes with shear strain rate (transformed to pressure difference) in reservoir simulator. It directly uses rhelogical relationship measured by viscometers, but it doesn't consider flow factor in micro-pore. Therefore for Non-Newtonian fluid we educed viscosity transfer relationship between macro- viscosity (viscometer rhelogical formula) and apparent viscosity (flow in capillary), it can be used in reservoir simulator, and it can reflect the difference between micro-flow and the normal flow.
