以辽河油田锦45区块22-023号井稠油和矿化水为实验原料,采用等效黏度的方法,制备了与现场性质相近的稠油水乳状液。研究了分散相微观形态对稠油水乳状液流变性的影响。结果表明,在分散相浓度较低时,乳状液流变性符合Bingham模型,而在高浓度时流变性符合Power law模型,分散相浓度一定时,微观粒径越小,乳状液的表观黏度越大,非牛顿流体性质越强,剪切稀释特性越明显。

Heavy oil and mineral water from 22-023 oil wells in Jin 45 of Liaohe oilfield were used as experimental materials. Through the equivalent viscosity methods,emulsion with similar properities to gathering site was prepared.The influence of droplet morphology on rheology of heavy crude oil emulsion was researched.The results showed that the rheology met Bingham model when the concentration of disperse phase was low,rather,the rheology met Power law model.The smaller of the dispersed micro particles,the greater of the apparent viscosity,the more significant of the non-Newtonian fluid properties and the more obvious of the shear thinning characteristics were.
