Development of new electrical technological systems and complex in the production of hard-to-remove oil reserves

When developing hard-to-recover hydrocarbon reserves, enterprises use various complexes and systems to facilitate technological processes that contribute to the lifting of heavy and viscous oils to the surface, as well as the extraction of light oils from lowpermeability reservoirs. During the operation of fields, abnormal situations also arise, caused by the appearance of asphalt-resin-paraffin deposits (ARPD) and salt deposits on the walls of tubing pipes, Christmas trees, process pipelines and equipment at the bottom. The existing methods of combating and preventing the manifestations of ARPD and salt precipitation can be conditionally divided into mechanical, chemical, thermal. To prevent and combat ARPD, as well as to reduce the viscosity of produced oils, thermal methods are most preferred, among which electrothermal methods are considered effective. In the case of salt sediments, technologies based on electrical energy are also an effective means of prevention, in particular, exposure of the well emulsion to a magnetic field.
