摘　　要：通过试验研究了大港油田 4个区块的稠油在不同温度、不同剪切速率及不同含水条件下的流变特性。结果表明 ,大港油田稠油在油层中具有牛顿流体的特性 ;而在井筒中 ,将会出现非牛顿流体的流动特性。含水原油在井筒中流动时将不会出现明显的乳化现象 ,粘度将随含水率增加而降低。Through experiments in lab,the rheological property of high viscous oil in 4 blocks of Dagang oilfield are studied at various shear rates, different temperature and water cuts The result obtained shows that the viscous oil in reservoir behaviors as Newtonian fluid and as non Newtonian in wellbore No apparent emulsion occurs when watered oil is flowing in wellbore, and the oil viscosity decreases with the increase of water cut
