Key words: drilling fluids, well-killing fluids, rheology, pseudoplastic fluid, periodic colloidal structures, surfactants, Darcy equation, non-linear filtration.
This article is devoted to the generalization of rheological models of the flow of various process fluids used in well construction. Particular attention is paid to pseudoplastic drilling fluids at the stage of drilling of reservoirs. It is shown that when filtering through the capillaries of the collector for pseudoplastic fluids, a deviation from the linear Darcy law is observed, which must be taken into account in core studies.
