EFFECTIVE HYDROCARBON MIXTURE FOR REMOVAL OF ASPHALTENES AND METHOD OF DISSOLVING OF ASPHALTENE ACCUMULATIONS

摘要

FIELD: hydrocarbon mixtures for dissolving of asphaltene accumulations and methods of treatment of oil wells with hydrocarbon mixture for removal of asphaltene deposits. SUBSTANCE: hydrocarbon mixture contains saturated hydrocarbons, polyaromatic compounds and alkyl benzenes. Content of components is selected by triple diagram. Starting point of boiling of hydrocarbon mixture is above 150 C. Method consists in introduction into wells of claimed mixture. EFFECT: economic efficiency and safety of composition, reduced time of dissolving of asphaltene deposits. 5 cl, 1 dwg
