Mathematical model for predicting yielding stress of mixed crude oil
摘要
Abstract
According to the experimental yielding stress of 5 crude oil samples and 42 mixed crude oil samples composed of them, a model for estimating the yielding stress of mixed crude oil is proposed by referring to gel-point and viscosity models of mixed crude oil. The prediction results of the yielding stress of 80 mixed crude oil samples shows that the average absolute error of the model is 1.92 Pa,and the average relative error is 50. 18%. Taking into account the fact that it is difficult to accurately measure yielding stress of oil crude,especially minor yielding stress,the estimating errors of this model is acceptable.关键词
