Abstract

Abstract: The rheology of crude oil emulsion of Bohai Oilfield is studied.Experimental results indicate that the viscosity values of the emulsion system decreases with the increase of temperature，rises with the increase of water cut，and drops with the increase of shear rate and grows with the increase of concentration of polymers.Moreover，the emulsion system is non-Newtonian fluid at a low temperature (0～55℃) and high water cut (﹥40%),the emulsion system is Newtonian fluid at high temperature (55～70℃) and low water cut(﹤40%).The reverse phase point of crude oil in NO.1 platform is about 70%,and NO.2 is about 60%.

Key words: crude oil emulsion, viscosity, water cut, temperature, shear rate, rheology, polymer
