Abstract
The invention relates to a cable electric submersible permanent-magnet linear reciprocating pump, on which are mounted an electric pump head and an electric cotrol gear. The electric pump head is connected with the cable jointed of the pump body via the cable. There are an oil tube and a casing outside the cable. A pump plunger is fixed at the bottom in the pump, and is mounted on the top of the pump plunger linear electric motor. A wire-armoured power cable is disposed in the oil tube. The oil winding of the linear motor is mounted on the active cell of the motor and the cable with the active cell is lifted from the oil well via the lift winch on the ground.
Description
Technical field
The present invention relates to a kind of electromechanical assembly, be specifically related to a kind of steel wire cable type electro immersion permanent magnet linear reciprocating pump, be mainly used in the well recovery of petroleum industry, belong to International Classification of Patents F04B17/03 " motor driving pump " technical field.
Background technique
Electro immersion permanent magnet formula straight reciprocating pump of the prior art, its power cable is bound on the outer wall of oil pipe, causes the damage of cable when the oil well operation removes oil pipe easily.Under abominable underground working, it is the main cause that electro immersion permanent magnet formula straight reciprocating pump damages that winding insulation lost efficacy.The electro immersion permanent magnet formula straight reciprocating pump of prior art, the coil winding of its electrical submersible linear electric motor is installed on the stator of motor, in case winding lost efficacy, have only tubing string is proposed from oil well together with the whole pump of electro immersion permanent magnet formula straight reciprocating pump, both delayed oil well production, a lot of workover costs has taken place again, has influenced the utilization efficiency in oil field.
Summary of the invention
Purpose of the present invention is to overcome above-mentioned deficiency, and a kind of steel wire cable type electro immersion permanent magnet linear reciprocating pump is provided.
Technological scheme of the present invention is as follows.
A kind of steel wire cable type electro immersion permanent magnet linear reciprocating pump is made up of electric controller, electric pump well head, oil pipe, sleeve pipe, cable joining, linear electric motor, the pump housing, pump plunger, annular flow path, steel wire cable, pipe nipple.The whole upper end of this device is equipped with electric pump well head and electric controller, and the electric pump well head is connected with the steel wire cable joint of the pump housing by steel wire cable, and the outside annular space of steel wire cable is oil pipe and sleeve pipe.The whole lower end of this device is equipped with pump plunger, and pump plunger is arranged at the inside, lower end of the pump housing, and the upper end of pump plunger is equipped with linear electric motor.
Described linear electric motor mainly are made of motor stator and the electric mover that is positioned at the motor stator inner chamber, and are provided with annular flow path, and electric mover does reciprocating linear motion in motor stator.
The lower end of the pump housing is equipped with pipe nipple and (connects electrical submersible synchronous permanent-magnet linear electric motor and plunger oil-well pump.
Steel wire cable is connected in series with electric mover and pump plunger and connects, and is arranged in oil pipe.
The present invention has overcome deficiency of the prior art, and a kind of solution of steel wire cable type electro immersion permanent magnet linear reciprocating pump is provided.Its power cable is not to be bundled on the oil-pipe external wall, but adopts the wire armoring power cable to be connected with the mover of electrical submersible linear electric motor.The wire armoring power cable is positioned at oil pipe, before the oil well operation removes oil pipe, earlier cable is proposed, and damages the phenomenon of cable when having avoided the oil well operation to remove oil pipe easily.The coil winding of electrical submersible linear electric motor is installed on the mover of motor, even winding lost efficacy, by the ground winch, only needs the mover of steel wire cable together with electro immersion permanent magnet formula straight reciprocating pump proposed to get final product from oil well, needn't propose the tubing string well workover.
