Abstract

In this study 2 samples of polyalkenyl succinimide were prepared by reaction between diethylenetriamine and pentaethylenehexamine with alkenyl succinic anhydride with a C20-26 alkyl chain length. The influence of alkenyl succinimides on the aggregative stability of petroleum dispersed systems was studied. The ability of alkenyl succinimides to influence the processes of crystallization of paraffins in oil and gas condensate, as well as their ability to influence the processes of aggregation of petroleum asphaltenes, was analyzed. The resulting compounds did not affect the crystallization processes in oil, but showed a depressant effect in gas condensate, the depression of the pour point was 13 °C, which turned out to be better than the industrially used additive (DMN-2005), which did not show an effect. PEHA-based alkenylsuccinimide was able to inhibit the aggregation of asphaltenes, increasing the ONCET point by 1.5 times compared to the original asphaltenes.
