Annotation:

A short list of the existing methods applied to prevent and remove asphalt-resin-paraffin deposits (ARPD) from oilfield equipment is presented in the article. Chemical methods related to the use of various additives, reagents and removing agents are considered in detail. The main classes of chemicals used when solving the problem of preventing and removing asphalt-resin-paraffin deposits are briefly describes. It is shown that in order to select the most chemically effective ways to prevent and remove organic deposits, it is necessary to obtain an adequate understanding of the composition, properties and structure of the source oil and the formed deposits. The mechanism of the reagents influence on asphalt-resin-paraffin deposits was clarified and it was revealed that the reagents BAF-1 and BAF-2 (technical conditional name of composites) when interacting with the deposits, grind the associates and ensure their uniform distribution in oil, thus improving its rheological properties.
