MAGNETIC WELL ACTIVATOR Russian patent published in 1995 - IPC

FIELD: oil producing industry. SUBSTANCE: magnetic well activator is a device designed to apply a magnetic field to water-oil-gas emulsion in the well. The device has a cylindrical body with a magnetic system mounted co-axially in the body on an attachment fixture. The magnetic system has a cylindrical hydraulic channel running along its longitudinal axis. The magnetic system is provided with rectangular permanent magnets. The magnets are mounted parallel with the body walls and the hydraulic channel. The magnetic system has two coupled blocks of diamagnetic material with its electrochemical potential close to zero. The blocks are cast as a hole spatial figure Maltese cross in its cross section. The magnets are paired diametrically with alternation of their poles NNSS, and they are turned through an angle of 45 deg relative to each other. The magnetic field strength is 38-42 kA/m. There is a clearance between the magnetic system and the body. The activator is placed in the string below the interval of start of complications: deposits of paraffin or salts, or above the oil well tubing in injection wells to enhance their intake capacity. EFFECT: higher activation efficiency. 3 cl, 3 dwg
