| 摘 要： | 采用RS75 旋转粘度计对稠油的粘温特性及流变特性进行了测量及研究。结果表明, 稠油的粘温特性在测量区间内(80～ 20 ℃)较好地符合Arrhenius 方程;温度越低, 稠油粘度对温度变化越敏感;不同温度区间稠油的活化能不同, 低温区间(36 .5 ～ 20 .3 ℃)内的活化能比高温区间(80 .0 ～ 55.9 ℃)内的活化能增长了45%;反常点温度为35 ℃, 当温度高于35 ℃时, 稠油表现为牛顿流体, 温度低于35 ℃时, 稠油表现为非牛顿流体;在非牛顿流体区, 稠油不具有触变性。

| Abstract: | Viscosity-temperature characteristics and rheology behavior for heavy oil were measured and researched by using RS75 rotary viscosimeter.The results show that viscosity-temperature characteristics are according with Arrhenius equation in temperature interval(80~20 ℃),viscosity is more sensitive to temperature changes in lower temperature,the activation energy rises 40% in lower temperature interval(36.5~20.3 ℃)more than in higher temperature interval(80.0~55.9 ℃),and heavy oil is Newtonian fluid above anomalistic point(35 ℃),non-newtonian fluid and without thixotropic property below anomalistic point. |
