彩南原油流变特性试验

Rheology Test of Cainan Crude Oil,OGST

彩南原油属石蜡基原油,析蜡点在48～50℃之间,反常点为20℃,针对这些特性,进行了原油热处理和添加改进剂综合处理试验。试验结果表明,原油的流变特性得到了改善,粘度、凝点、反常点及屈服应力值均有明显下降,根据试验结果确定了原油综合热处理的温度、加剂量等参数,有效地指导了彩南原油管道的安全运行。

Cainan crude oil is a parafin-based crude. Its wax precipitation point is between 48 ~50℃ and anomalistic point is at 20℃. In the light of these characteristics, the heating and drugging treatment tests have been made. The results show that the oil's rheology has been improved. Its viscosity,set point,anomalistic point,and yield stress are obviously reduced. Based on the test results, the parameters concerned of the heating temperature and injection rate of additive have been determined,which effectively guides the operation of Cainan oil pipeline.
