摘要/Abstract

摘要： 通过对流变仪温控原理的研究,分析了行业标准《原油析蜡点的测定旋转黏计法》中采用连续降温方式的不合理性,建议采用分段降温的方式。在低温段曲线呈非线性关系的情况下,若按照标准推荐的计算析蜡点软件计算,会造成析蜡点偏小或偏大。为此,提出了按照低温段曲线偏离高温段拟合直线的程度,判断析蜡点的改进意见。

Abstract: The irrationality of continuous cooling method in industry standard for "Determination of wax appearance temperature of crude oil-test method by rotational viscometer" is analyzed through investigation on temperature controlling principle of rheometer, and the suggestion by staged cooling process is put forward. In the matter of the program of calculating wax appearance temperature, if calculating by software recommended in the standard, low or high wax appearance temperature will appear when the curves of low temperature section become nonlinearity. The improvement suggestion is given that the wax appearance temperature of crude oil should be determined based on the deviating degree of low temperature section curve and simulated straight line of high temperature section.

Key words: rotational viscometer, wax appearance temperature, cooling process, segment temperature decline
