NEW METHODS OF STRUGGLE WITH ASPHALT-RESIN-PARAFFIN DEPOSITS IN THE PROCESSES OF OIL TRANSPORTATION

Modern views on the state of the problem considered asphalt-resin-paraffin deposits (ARPD) in oilfield equipment and possible methods for its solution. The main factors of the ARPD formation listed in this paper. Special focus given to the group chemical composition of the crude and mutual influence of separate high-molecular crude oil components on the structurization in the oil system at low temperatures. The chemical methods concerning with application of various additives, reagents and removers are considered in more detail. The mechanism of action of reagents on ARPD was clarified and was it determined that the reagents of BAF-1 and BAF-2 in interaction with sediments, grind associates and ensure there uniform distribution in oil.
