Abstract
The oil rod clipping centralizer is used to prevent oil pumping rod of oil pumping unit or spiral pump against accentric wear during oil extraction. The eccentric wear of oil pumping rod caused by bending of oil pipe will damage oil pumping rod and oil pipe. The oil rod clipping centralizer of the present invention as a kind of eccentric-wear preventer may be clipped to oil pumping rod easily to prevent the hard friction between the oil pumping rod and the oil pipe via wrapping the oil pumping rod.
Description
Rotary oil rod clipping centralizer is in recovering the oil in the oil field, for the beam hanger that prevents oil pumper moves up and down or eccentrically worn tubing during the beam hanger rotation work of screw pump, causes damage equipment and the nonmetal wear resistant tools of the anti-eccentric wear of a kind of novel down-hole oil production that uses.
Rigid friction takes place with it because of tubing bending in the beam hanger of rod-pumped well and the screw rod of screw pump when work, wearing and tearing for a long time cause beam hanger to rub the infringement of leaking with the oil pipe mill, have therefore increased equipment scrapping and operating cost.
The present invention provides a kind of cassette tape easily on beam hanger, and the encirclement beam hanger makes itself and oil pipe that the anti-eccentric wear instrument of a kind of novel down-hole oil production of rigid friction directly not take place.
The present invention realizes like this; the present invention designed rotary band pin thread on set upright clip and the band box the following clip of setting upright; and the upper and lower clip side of setting upright cut the beam hanger insertion groove; so that beam hanger inserts spacing beam hanger hole; make it surround beam hanger by upper and lower the setting upright between clip 90～270 degree that turn clockwise this moment, and the protection beam hanger with oil pipe rigid CONTACT WITH FRICTION does not take place in 360 degree scopes; avoid the coup injury of beam hanger and oil pipe, the protection oil production equipment.The present invention can improve the oil well effect, reduces the oil producing operation cost.
Concrete structure of the present invention is provided by the following drawings and embodiment;
Figure one is that of the present invention cuing open shown total figure;
Figure two is installation site of the present invention schematic diagrames.
Describe working condition of the present invention in detail below in conjunction with accompanying drawing:
Find out by figure one: on set upright clip 1; Guiding gutter 2; Under set upright clip 3; Spacing beam hanger hole 4; Beam hanger insertion groove 5; Spacing spinner 6.
Found out by figure two: the present invention 7; Beam hanger 8; Oil pipe 9; Beam hanger box cupling 10.
By figure one, figure two as can be seen, when oil well production, the screw rod dynamical system is rotated the rotation of interlock beam hanger, and gives screw pump, screw pump work lifting oil column with rotatory force by the beam hanger transmission.Because the well depth tubing bending, brokenly make beam hanger become bent rigid contact tube inner wall, beam hanger is rotated be subjected to very big frictional resistance, reduce system behavio(u)r, destroy system equipment.The present invention is installed on the position 7, and when oil well production, by the beam hanger of setting upright of the present invention, not contact friction tube inner wall rotated freedom when beam hanger was rotated, and realized the purpose of protection facility.
The present invention can improve the effect of screw rod dynamical system, and the production equipment of protection oil well reduces the oil producing operation cost.
Claims (2)
1, a kind of can solve beam hanger in oil pipe because of crooked and rotate the instrument that causes the wearing and tearing production facilities, comprising: on set upright clip 1; Guiding gutter 2; Under set upright clip 3; Spacing beam hanger hole 4; Beam hanger insertion groove 5; Spacing spinner 6.
2, according to the described instrument of claim 1, it is characterized in that having designed and set upright clip 1 and set upright the positioning of rotating of clip 2 down by spacing spinner, realize surrounding beam hanger, solved the not problem of direct friction oil pipe of beam hanger;
