Mechanism of magnetic field effect on hydrocarbon systems

Purpose. The aim is to analyze the problem of preventing the asphalt-resin-paraffin deposits (ARPD) in the oil industry equipment and to justify application of paraffin control methods; to review modern approaches to ARPD problem and possible methods of its solution; to analyze existing methods of hydrocarbons ‘treatment by magnetic field. Methods. Investigations showed that application of magnetic anti-paraffin device (MAPD) makes it possible (during 24-hour operation of the oil well) to double the time between overhauls of oil wells equipped with sucker rod pump installations. Findings. The results obtained due to MAPD application in oil wells equipped with sucker rod pumps give an opportunity to use it in oilfield practice employing free-flow production method or in wells serviced by centrifugal pumps and in oil pipe lines. Originality. Application of up-to-date magnets with poles from 60 to160 kA/m enables to decrease ARPD in oil equipment. Practical implications. The results of MAPD implementation at Boryslav field, in particular in wells No 1343, 797, 948 proved the efficiency of the device application and doubled the overhaul period. Magnetic field effect on hydrocarbons is analyzed in the article.
