Изменение Состава И Свойств Асфальтенов При Физическом Моделировании Процесса Вытеснения Тяжелых Нефтей Растворителями На Основе Н-Алканов

This paper addresses the problem of asphaltene deposition during oil displacement by n-alkanes. To solve this problem, an experimental modeling of physical and chemical effects of hydrocarbon solvents in oil-saturated reservoir model using a laboratory setting. The purpose was to create a model of oil displacement in the laboratory to determine the optimal number of different inhibitors of asphaltene precipitation. As a result, it was determined that for heavy oil of Tatarstan benzene resins as inhibitors of the effectiveness is not much different from the expensive synthetic products.
