Abstract
A strong-magnetic sealing relay pump for a pumped well comprises an upper joint and a lower joint which are connected with a center tube. The strong-magnetic sealing relay pump is characterized in that a strong-magnetic rigid body sealing part is disposed between the upper joint and the lower joint on the center tube, and a press sleeve, a ball seat and a steel ball placed on the ball seat are arranged in the lower joint of the center tube. During working, the strong-magnetic sealing relay pump is connected onto a sucker rod so as to move downwards to the inside of an oil tube to form a piston, and the oil tube is adopted as a pump cylinder, thereby forming an oil-well pump structure. The strong-magnetic sealing relay pump has the advantages of adopting the strong-magnetic rigid body sealing part to generate a strong magnetic field, being capable of effectively realizing pour point depression and paraffin inhibition, and simultaneously resolving the problem that original sealing parts are easy to be damaged and fall off, thereby effectively preventing leakage and pump jamming.
Description
Technical field:
The utility model relates to the down-hole oil production instrument in the oil production technology of oil field, the strong magnetic seal booster pump of specifically a kind of pumping well.
Background technique:
In the pumping production technology, what its sealing of oil tools such as existing exhausting-aid device, multistage pump plunger was adopted is rubber seal.In pumping unit moved up and down, the sucker rod that is connected on the pumping unit also moved up and down, because the rubber seal in the oil tool rubs serious fragile and comes off, had caused the phenomenon of leakage and holddown.In addition, existing oil tool does not have pour point depression and wax control effect.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of Sealing that can prevent and damages and come off, have simultaneously the strong magnetic seal booster pump of pumping well of pour point depression and wax control effect.
The utility model is to realize like this, it comprises upper connection and the lower contact that connects center tube, it is characterized in that: between upper connection on the center tube and lower contact, be provided with strong magnetic rigid body Sealing, in the lower contact of center tube lower end, be provided with gland and ball seat and place steel ball on the ball seat.During work, be connected on the sucker rod, being lowered into oil pipe inside becomes piston, and oil pipe is a pump barrel, forms the oil pumping pump structure.
The utility model has the advantages that and utilize strong magnetic rigid body Sealing to produce high magnetic fields, pour point depression and wax control solve the fragile and problem that comes off of former Sealing simultaneously effectively, thereby prevent to miss the generation with the holddown phenomenon effectively.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
By accompanying drawing as can be known, the utility model is made of upper connection 1, center tube 2, strong magnetic rigid body Sealing 3, gland 4, ball seat 5, steel ball 7 and lower contact 6.Upper connection 1 and lower contact 6 are connected to the upper and lower end of center tube 2 by the screw thread mode, strong magnetic rigid body Sealing 3 be enclosed within on the center tube 2 and place upper connection 1 and lower contact 6 between, be provided with gland 4 and ball seat 5 successively in the lower end of lower contact 6 inner central tubes 2, steel ball 7 places on the ball seat 5.During work, be connected to this strong magnetic seal booster pump on the sucker rod and be lowered in the oil pipe 8, when pumping unit is descending, at this moment the crude oil in the oil pipe 8 enter in the hole of lower contact 6 and wash steel ball 7 on the ball seat 5 open, crude oil is through center tube 2, go out from the oil outlet of upper connection 1, enter in the upper level booster pump; When pumping unit was up, steel ball 7 was fallen on the ball seat 5, had formed the effect of one-way sealing valve.Along with sucker rod constantly moves up and down, this booster pump is constantly extracted crude oil out ground.
