摘要:

实验考察了温度、含水率、剪切速率和聚合物浓度等因素对渤海油田原油乳状液流变性的影响,结果表明乳状液黏度随温度上升而下降,随含水率上升而上升,随剪切速率上升而下降,随聚合物浓度增加而上升。在0~55℃含水率高于40%时,乳状液体系呈现非牛顿流体特性,在55~70℃含水率低于40%时,乳状液体系呈现牛顿流体特性,渤海油田一号平台原油的转相点为含水率70%左右,二号平台原油的转相点为含水率60%左右。

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
