The log-log formulae recommended in this paper can be used for calculating the viscosities of mixed liquids with multicomponents whose viscosity indexes are close to each other. The formulae in other relevant literatures are only suitable for special oil products and diluents. and some of them are not applicable or have no practical value because of the high error rate on calculation or the incorrectness of the formula itself.

通过将稀油掺入稠油的降粘试验,总结分析了混合液粘度的有关计算公式及曲线,并推荐使用双对数公式。该公式可用于计算粘度指数接近的多组份混合液的粘度。而其他有关文献介绍的公式,只适用于特定的油品及稀释剂,其中有的公式还因计算的误差率甚高或公式本身有误,不宜使用或无实用价值。

In this paper chemical compositions of some magmatic rocks of Mesozoic and Cenozic era in china were analysed. The melting points, refractive indexes and specific gravity of artificial glasses in these rocks were determined, as well as their viscosities at different temperatures were calculated.

本文研究了我国中、新生代一些岩浆岩的化学成分、熔点、人工玻璃的折射率和比重以及它们在不同温度下的粘度。在常压下岩石酸度愈大,熔点愈高。熔点与岩石的Fe~(2+(+Fe~(3+)+Mn+Mg±Ca为反相关;与Si+Al+K+Na为正相关。计算粘度与温度的关系表明,酸度愈大,粘度愈大;碱度愈大,粘度愈小,温度愈高,粘度愈低;同一温差下,酸度愈大,粘度变化愈大。

This article systematically gives the hydraulic calculation formulas of oil-water emulsion using the process flow of gathering and transferring mixed with surfactant water emulsifying the mixed fluid and decreasing its viscosity in heavy crude oilfields. The article also introduces a simple and convenient method used by Bechtel Co. at Dagang Oilfield.

本文系统地给出了稠油油田采用稠油掺活性水乳化降粘集输工艺流程时,油水乳状液的水力计算公式.当流态为层流时,介绍了塑流型、假塑流型和胀流型非牛顿流体的水力计算公式;当流态为紊流时,应通过实验确定摩阻系数,然后按达西公式计算压降.当油水乳状液为牛顿流体时,先按流态计算出水力摩阻系数,然后根据文献中给出的公式计算粘度,再按达西公式计算压降.最后介绍了美国Bechtel公司在大港油田采用的一种简便方法,即已知纯油在某温度下的粘度和油水乳状液的含水(盐)量,并根据本文附图曲线和公式(乳状液粘度=纯油粘度×粘度比),可估算出该温度下油水乳状液的粘度,进而计算出压降.
