Abstract
The effect of natural surfactants (SA) on the efficiency of the polymer additive against the formation of deposits in high-paraffin oil with increased content of resin-asphaltene components is investigated. It is demonstrated that the addition of the polymer to oil, either individually or with natural SA, causes a decrease in the amount of the formed deposits. It is determined that the maximal inhibiting ability is exhibited by the composition containing the polymer and 0.03 wt. % naphthenic acids (SA). Natural SA, either alone or together with the polymer, when added to oil, cause a decrease in the size of associates of paraffin hydrocarbons and their aggregates in the oily fraction of the oil deposits under investigation.
