进口混合原油互溶稳定性的研究

Study on miscibility and stability of imported mixed crude oil

对委内瑞拉Merey原油及安哥拉Nemba原油的性质进行了分析,并采用显微镜法和稳定性分析仪,考察了2种原油混合时的相容性及其混合原油的稳定性。结果表明:Merey原油的S分离值较高,储存稳定性较低,而Nemba原油的储存稳定性高。当 m (Merey原油)∶ m (Nemba原油)为2∶3时,混合原油S分离值随着储存时间的延长快速增加,不适宜长期储存;当 m (Merey原油)∶ m (Nemba原油)为 4∶1 时,混合原油S分离值随着储存时间的延长缓慢增加,可以储存较长时间。

The properties of Merey crude oil from Venezuelan and Nemba crude oil from Angolan were analyzed, and the miscibility and stability of the two kinds of crude oil were investigated by the microscope and stability analyzer. The results showed that the S separation value of Merey crude oil was higher and the storage stability was lower, while the storage stability of Nemba crude oil was higher. S separation value of the mixed crude oil with m (Merey crude oil)∶ m (Nemba crude oil)2∶3 increased rapidly with the extension of storage time, and the oil was unsuitable for the long-term storage;while S separation value of the mixed crude oil with m (Merey crude oil)∶ m (Nemba crude oil) was 4∶1 increased slowly with the storage time, and the oil was suitable for the longtime storage.
