| 摘 要： | 原油的升温过程和降温过程有着本质区别，单凭某一过程的剪切应力－温度曲线来确定析蜡点等特征温度必然存在误差。针对这一问题提出了连续升降温过程平均粘温曲线法，该方法可经在较高的温度范围内同时测定油样的析蜡点、异常点和凝点等特征温度。介绍了该方法的操作过程，利用常规方法证实了其可靠性。

| Abstract: | The characteristic temperatures of crude oil mean the special temperatures, such as wax appearance point and pour point and so on,corresponding to the abrupt change of the rheological properties of the oil. In the light of super-cooling and the super-heating problem of wax crystallization and melting during the continuous cooling and heating process,it is impossible to exactly determine the characteristic temperatures such as wax appearance point only depending on the shear stress and temperature curves for one of the processes. At the same time,it is difficult to exactly measure the wax appearance point or cloud point of crude oil by means of eye-measurement method because of oil always is fuscous. Therefore,a method of mean viscosity and temperature curve for continuous heating and cooling process is presented. To a wider extent of measuring temperature, this method can measure not only wax appearance point but also abnormal point and pour point. The conventional methods confirms its reliability. |
