STUDY OF THE VISCOSITY-TEMPERATURE PROPERTIES OF HEAVY OIL FROM THE YABLUNIVSKY FIELD OF UKRAINE

Abstract

Viscosity-temperature properties of high-viscosity oils from 3 wells of the Yablunovsky field (Poltava region, Ukraine) were studied using a rotary viscometer. According to the nature of the curves of the dependence of dynamic viscosity and shear stress on the shear rate, the nature of the flow of these oils is established, which is of practical importance for effect evaluating of various methods of action on the rheological behavior of these oils during their extraction and transportation.
