| 摘要 |
The invention relates to the production and use of an asphaltene-controlling additive compound for oil, which, when added to heavy oil, results in the asphaltenes remaining suspended or being dissolved, producing a viscosity reduction effect and thereby preventing the formation by precipitation of asphaltene aggregates in oil wells and storage tanks, as well as preventing the obstruction of ducts. The molecular binding provided by the components of this novel additive compound is such that the final liquid is miscible in any type of oil. At present solubility models exist that use different methods in order to control asphaltenes; some use solvents that create other problems in terms of the physical and chemical stability of the oil, while others, such as the use of steam or heat, provide a temporary solution since the oil ultimately returns to the initial conditions thereof owing to the use of reversible processes. |
