Synthesis and Mechanism of Dendritic OilSoluble Visbreaking Agent

Abstract

Abstract: In view of problems that the oil?soluble heavy oil visbreaking agent has limited conditions for application and low response for visbreaking, a new kind of dendritic oil?soluble heavy oil visbreaking agent was developed. Its visbreaking mechanism is that the polar group in the agent can form hydrogen bond by combining with colloidal asphaltene, and the long?chain alkyl group in it could adsorb a part of colloidal asphaltene, thus inhibiting the accumulation of colloidal asphaltene. In addition, the dendritic structure of this agent allows the colloidal asphaltene to be further dispersed for the purpose of visbreaking. Case study indicates that this agent is better than the oil?soluble visbreaking agent available at present and suitable for visbreaking of multiple heavy oils
