Abstract

The invention discloses an all-metal screw oil well pump for a deep well, which comprises a pump cylinder, a fixed valve, a reducer union and an oil pipe, wherein an upper submersible motor is fixed on the lower end of the pump cylinder, an upper bearing base and a lower bearing base are respectively fixed on the upper part and the lower part of the pump cylinder, a screw is arranged in a pump cylinder cavity, the upper end of the screw is fixed on the upper bearing base through an upper bearing, the lower end of the screw is fixed on the lower bearing base through a lower bearing, the lower end part of the screw is fixedly connected with a main shaft of the submersible motor through a coupler, an oil inlet is arranged in the outer wall of the bottom of the pump cylinder, and the screw is in clearance fit with the pump cylinder. The all-metal screw oil well pump for the deep well has a simple structure, is convenient in operation and maintenance, thoroughly solves the problem of eccentric wear of a rod pump and is convenient in processing; and service life is prolonged and production cost is lowered.

Description

Deep-well is with full-metallic screw type oil well pump
 
Technical field
The present invention relates to a kind of improvement of oil well pump, be applied to field of petroleum exploitation, a kind of specifically deep-well is with full-metallic screw type oil well pump.
Background technique
At present, the oil recovery machiner that on the oil field, uses mainly contains several kinds: the one, and plunger oil-well pump; The 2nd, rod-type drive screw pump; Thereby plunger oil-well pump is a pumping unit to be driven plunger through sucker rod and in pump barrel, moves reciprocatingly and realize the purpose of oil pumping.Rod-type drive screw pump is that motor rotates in stator through the rotor that sucker rod drives screw pump, thereby realizes the purpose of oil pumping.Wherein the stator of screw pump is special rubber, complex structure, and processing is difficulty very.And above two kinds of pumps make the wearing and tearing of oil pipe and pull bar owing to all there is eccentric wear in the reason that sucker rod is arranged, have reduced working life.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, easy to use, adopt oil-submersible motor to do power, drive threaded screw rod and do high speed rotary motion, thereby crude oil is risen along screw thread rotation, up to the deep-well that gives rise to ground with full-metallic screw type oil well pump.
In order to reach above purpose, the technological scheme that the present invention adopted is: this deep-well comprises pump barrel, standing valve, reducer union and oil pipe with full-metallic screw type oil well pump; Reducer union is fixedly connected on the lower end of oil pipe, and the lower end of reducer union is fixed with standing valve, and the lower end of standing valve is fixed on the top of pump barrel; It is characterized in that: fix oil-submersible motor in the lower end of pump barrel; Upper and lower at pump barrel is fixed with upper bearing bracket and step respectively, and screw rod is located in the pump barrel chamber, and the upper end of screw rod is fixed on the upper bearing bracket through upper bearing (metal); The lower end of screw rod is fixed on the step through lower bearing; The underpart of screw rod is fixedly connected with the main shaft of oil-submersible motor through coupling, on the outer wall of pump barrel bottom, is provided with oil inlet hole, and screw rod and pump barrel are Spielpassung.
Beneficial effect of the present invention is: simple in structure, easy to operate, be convenient to safeguard, and thoroughly solved bar pump eccentric wear problem, simultaneously easy to process, prolonged working life, reduced cost of production.
Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present invention;
Among the figure: 1, oil pipe; 2, reducer union; 3, standing valve; 4, upper bearing bracket; 5, upper bearing (metal); 6, screw rod; 7, pump barrel; 8, lower bearing; 9, step; 10, oil inlet hole; 11, coupling; 12, oil-submersible motor.
Embodiment
Make the present invention with reference to accompanying drawing 1.This deep-well comprises pump barrel 7, standing valve 3, reducer union 2 and oil pipe 1 with full-metallic screw type oil well pump, and reducer union 2 is fixedly connected on the lower end of oil pipe 1; The lower end of reducer union 2 is fixed with standing valve 3; The lower end of standing valve 3 is fixed on the top of pump barrel 7, it is characterized in that: fix oil-submersible motor 12 in the lower end of pump barrel 7, be fixed with upper bearing bracket 4 and step 9 in the upper and lower of pump barrel 7 respectively; Screw rod 6 is located in pump barrel 7 chambeies; The upper end of screw rod 6 is fixed on the upper bearing bracket 4 through upper bearing (metal) 5, and the lower end of screw rod 6 is fixed on the step 9 through lower bearing 8, and the underpart of screw rod 6 is fixedly connected with the main shaft of oil-submersible motor 12 through coupling 11; On the outer wall of pump barrel 7 bottoms, be provided with oil inlet hole 10, screw rod 6 is Spielpassung with pump barrel 7.
During use, the main shaft of oil-submersible motor 12 rotates, and drives screw rod 6 through coupling 11 and rotates; Screw rod 6 is Spielpassung with pump barrel 7, and can inside do and rotate freely motion, when arriving certain speed; Producing negative pressure makes crude oil pass through the oil inlet hole 10 entering pump housings; Liquid rises along thread helix, gets into oil pipe 1 through standing valve 3 backs, up to giving rise to ground.When shutting down, standing valve 3 lockings, crude oil can not descend Lou.
