Фотоколориметрический метод контроля осаждения асфальтенов при вытеснении природных битумов растворителями на основе легких 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 de-asphalted oil is effective enough stabilizer of asphaltene precipitation is not conceding ecologically dangerous aromatic hydrocarbons and petroleum resins as inhibitors of the effectiveness is not much different from the expensive synthetic products.
