摘要

本文概述了广泛应用的液体混合物粘度计算方法，以及原油的流变特性。它专注于流变特性的评估，特别是为了评估不同温度和流速下管道中的流动条件，尤其是在含蜡原油的情况下。提出并描述了一种适用于实际目的的具体计算程序，即以电子表格计算器的形式在现场实施。使用这种方法，可以计算已知组分混合物在给定温度下，在与指定直径的圆形管道中的指定流速范围相对应的剪切梯度范围内的流变特性。所提出的计算方法在特定类型的油及其混合物的性质上得到了验证。

Determination of rheological properties of crude oil blends

The article presents an overview of widely applicable methods of calculation of viscosity of liquid mixtures, as well as rheology characterisation of crude oil. It is focused on the evaluation of rheological properties, particularly in order to assess the flow conditions in pipelines at different temperatures and flow rates, especially in the case of waxy crude oils. A specific calculation procedure was proposed and described, suitable for practical purposes, i.e. field implementation in the form of a spreadsheet calculator. Using this method, it is possible to calculate the rheological properties of a mixture of known components at a given temperature over a range of shear gradients corresponding to a specified range of flow rates in a circular pipeline of specified diameter. The proposed calculation method was verified on the properties of specific types of oils and their mixtures.
