Comparative study of prediction methods of gel point of mixed crude oil

Abstract

Abstract:Gel point is an important parameter of the safe pipeline transportation of the waxy crude oil, and predicting the gel point of the mixed crude oil quickly and precisely has a certain practical significance for this kind of mixed transportation. By adopting the scientific evaluation method of the prediction model, the adaptation of the Model Li Chuangwen, Model Liu Tianyou I, Model Liu Tianyou II, and Model Chen Jun to predicting the gel point of mixed crude oil transported in a certain pipeline is analyzed and compared, by which the most appropriate model for the prediction of the mixed crude oil is confirmed. It is found that Model Liu Tianyou I is most suitable for the mixed crude oil. Therefore, from the engineering point of view, for the mixed crude oil mentioned in this text, the gel point calculated by Model Liu Tianyou I has a certain reference value.
