原油老化对流变性的影响

Influence of Crude Ageing in Its Rheological Properties

对老化给原油流变性带来的影响进行了实验研究。以东黄线原油、中原原油为例，分别进行了自然状态下以及预处理后原油的老化实验，结果表明，原油的老化程度因原油的组成、原油状态、环境状况和老化时间等条件的不同会有所不同。不管是未经预处理的原油，还是已经预处理的原油，或是重复预处理的原油，都存在老化而使原油流变性恶化的问题，应引起科研和生产领域的重视。还对原油老化机理进行了探讨。

Test result shows that with the difference of its composition, state, environmental condition' and ageing time etc, the crude ageing levels may be different. Crude whether unpretreated or pretreated or repretreated are all having ageing problems and making crude rheological Properties worsen.
