The limited world oil reserves force to actively develop and use fields with relatively low debit wells, as well as fields with difficult oil production conditions, with high-viscosity oil and with a significant content of foreign inclusions. One of the most unpleasant and serious complications in oil equipment is asphalt-resin-paraffin deposits. Therefore, one of the most important tasks is to study the mechanism and conditions of formation of asphalt-resin-paraffin deposits, as well as the

Analysis of wells in which asphalt-resin-paraffin deposits are observed, shows that the presence of paraffin, regardless of its amount in oil, poses many technological and technical tasks related to the elimination of complications associated with asphalt-resin-paraffin deposits. The presence of asphalt-resin-paraffin deposits leads to a decrease in the flow rate of wells due to clogging of pores and deterioration of filtration of oil-saturated formations. During downhole oil production, asphalt-resin-paraffins accumulate in the form of deposits on the walls of pump-compressor pipes (tubing) and oilfield equipment, thereby reducing the cross section of pipelines and lead to a decrease in the flow rate of wells. In a given hour, there are close to twenty new ways of fighting with embedded paraffin. Leather with methods of combating paraffin waxing in the process of choosing effective methods for preserving and visualizing paraffin waxes without preserving the trivial mid-repair period of robotics in the drill holes, for improving the efficiency of mathematics. The use of magnetic oil treatment devices is effective in preventing these problems. The high practical efficiency of such devices is evidenced by the increasing attention paid to the development of these devices and their patenting by various foreign firms. One such device, called a magnetic anti-paraffin device, will be discussed in detail in this paper. The device was tested at the Boryslav field from 2002 to 2007, where it gave good results in contrast to other methods. MAP has significantly reduced the percentage of asphalt-resin-paraffin deposits formation in the production area and transferred the process of their utilization to the refinery №10 in Boryslav, which in turn allows to preserve valuable components of asphalt-resin-paraffin deposits for their further use and improve the environmental condition of oil fields. The use of magnetic antiparaffin device can be effective both in the gushing of the well and in the operation of its deep-rod centrifugal and diaphragm pumps, as well as on oil pipelines. The maintenance period due to the use of magnetic antiparaffin device, in particular at OJSC Ukrnafta, increased 1.5-2.6 times. The advanced MAP device differs from other magnetic devices for liquid processing in that no power supply to the device is required for work as it works on permanent magnets. Keywords: pipeline transportation of petroleum products, trunk oil pipelines, high viscosity oil, paraffin deposition, permanent magnetic field.
