| description | FIELD: devices of cathodic protection of the oil field equipment. ^ SUBSTANCE: the invention is dealt with devices for cathodic protection of the oil-field equipment, in particular, the deep-well pump. The device for a cathodic protection of the well pump includes a station of a cathodic protection - SCP connected by an interconnect cable on a daylight surface to the casing string and to the anodic earth electrode. At that the SCP is additionally connected to the housing of the well pump by an additional current core of the electric cable for power feeding to the electric motor of the well pump. The electric cable for power feeding to the electric motor of the protected well pump is equipped with the additional current conductive core intended for connection of the well pump housing to the SCP. At that in the capacity of the additional core of the cable they use the core similar to the other cores of the electric cable and all current conductive cores of the electric cable are packed into the armor. The technical result is development of the device for a cathodic protection of the well pump sinking in the borehole without decrease of efficiency of the device operation as the well pump is sinking away from the daylight surface. ^ EFFECT: development of the device for a cathodic protection of the well pump ensuring its effective operation as sinking in the borehole. ^ 4 cl, 2 dwg, 1 tbl |
