1.1.2 Working principle The pump is installed above the hydraulic packer. The seal pump is used to seal the centrifugal pump, the protector and the motor. Only the sieve pipe and the oil pipe are connected through the packer to communicate with the lower reservoir. Below the packer Of the liquid into the unit through the tubing and sealed tube of the annular space into the suction port, the role of the centrifugal pump out of the wellhead.
1.1.3 Sealing scheme The upper sealing principle As shown, remove the cable sheathing and expose the three wires from the through hole in the sealing flange. The two ends of the wire are covered with sealing rubber, and then on the rubber side and Above were covered with baffle, tighten the wire block, so sealed.
1968-), Shandong Linyi, undergraduate, engineer, mainly engaged in work for the oil field law and order fire and rescue.
The principle of the lower seal as shown, the external use of the guide with the shroud connection, through the thread to seal; internal short section of the screen from the middle hole through the guide device, through the apron with the guide device to seal.

Has the following characteristics: without affecting the normal work of the pump case, to prevent the upper part of the oil or water pollution caused by the increase in water content; further excavation casing damage potential production to restore the production loss; low cost, easy Operation, but the use of significant results; further enrich and optimize the stratified oil production process, improved oil recovery.
Cable Seal Seal Rubber Seal Flange Top Seal Principle 1 point Seal Flange Schematic Motor-Guide 'Lower Seal Principle 1.2 Job Requirements Shroud Seal Apron Reducing Guide Schematic The program is an increase in the upper part of the shroud (At least more than 24 meters); the installation of a workover rig that is capable of lifting more than 35 meters (at least greater than 24 meters); installation of the workover rigs; The process of the need for shroud installation, cable sealing and cable connection operation, the installation time relative to the general pump longer, in addition to providing the necessary assistance, the well killing and other appropriate security measures; downhole process to control the speed, to prevent bump Cable, damaged seal or shroud.
2.2 The main configuration of the submersible pump technology (4) power cables, transformers, control cabinets, etc. 2.2 size data calculation Shield higher than the pump head 37mm, the next section pump length 5377.7mm, motor length 8248.3mm, protector Length 3406.2mm, the middle shackle 35x2mm shroud, three shrouds (down to page 59) for the general browsing staff to view the download, the background by the relevant management personnel to upload information, through / dismissed, publishing and other operations.
