Devices to prevent asphaltene deposits (AFS), scaling and corrosion DEEP WELL EQUIPMENT

摘要

The invention relates to the oil industry in particular to protect the tubing (tubing and pumping deep wells equipment) from corrosive destruction and asphaltene sediments.; The problem is solved in that the device, consisting of tubing pipe with permanent magnets for magnetic treatment, the magnesium element of electrochemical protection (ECP) from corrosion and using centralizers, the permanent magnets arranged in a pipe the same polarity to each other through ferromagnetic gasket in the tube from nonmagnetic material successively to magnesium element and a centralizer arrange holes for oil passage.; The combination in one unit of magnetic treatment of oil and electrochemical protection against corrosion of equipment leads to increased mezhochistnogo and overhaul period, which increases the efficiency of operation of the well as a whole.; 1 n.p.f.i., 1 fig.
