RHEOLOGY OF STRUCTURED NON-NEWTONIAN OILS IN THE GAS-LIFT RECOVERY METHOD

Consideration has been given to the problems of rheology of non-Newtonian oils in the gas-lift method of recovery. An analysis of the state of a non-Newtonian oil containing asphalt resinous substances has enabled the authors to investigate structuring and its infl uence on rheological properties. The formation of adsorption fi lms on the surface of water droplets and gas bubbles leads to obtaining stable oil emulsions. The thickness of the adsorption layer as a function of the content of asphalt resinous substances has been calculated. Experimental investigations into the rheology of non-Newtonian oils have been proposed and rheological models have been obtained.
