摘要
在管流试验装置上研究了含蜡原油的触变性 ,对原有的触变性描述模式进行了改进。实验发现 ,同样的剪切历史 (管道停输前的剪切历史和停输过程中凝油的收缩 )对蜡晶结构的恢复虽然具有一定的不确定性 ,但重新启动后的平衡剪切应力几乎不受这种不确定性的影响。
An experimental instrument for researching pipe flow is used to study thixotropy of waxy oil flowing in pipeline. The results show that the effects of histories, including shear process before shut up of pipeline and the contract of crude oil in the shut up course, on the recovery of the waxy structure are uncertain. The uncertainty has little influence on equilibrium shear stress after restart up of oil flowing.
