Problems solved by technology

Although there are many types of anti-eccentric wear devices for sucker rods, the effect of anti-eccentric wear is not obvious during field use, and there is still a problem of local severe wear, which causes damage and breakage of sucker rods and oil pipes, directly Affect the normal production of the pumping well, resulting in an increase in the maintenance cost of the oil well operation

Embodiment Construction

[0012] The present invention will be described in detail below in combination with specific embodiments.

[0013] The invention relates to a spherical anti-wear body anti-eccentric wear device for pumping wells, which is provided with a central rod 3 on which a spherical anti-wear body 2 is sheathed. The upper and lower sides of the center rod 3 and the upper and lower sides of the wear-resistant body 2 are respectively provided with an upper limit ring 1 and a lower limit ring 4 fixed on the center rod 3, between the upper limit ring 1 and the lower limit ring 4 and the wear-resistant body 2 There are gaps. The anti-wear body 2 is provided with a spiral groove from top to bottom, which is used to provide force in the circumferential direction to the anti-wear body 2 when the fluid moves up and down, so that the anti-wear body 2 rotates around the central rod 3. When the sucker rod encounters In the case of eccentric wear, the uniform wear of the wear-resistant body 2 is real...

Abstract

The invention relates to a pumping well anti-eccentric wear device with a spherical wearproof body. In the field use process of a pumping rod anti-eccentric wear device, the anti-eccentric wear effect is not obvious, and a pumping rod and an oil pipe are prone to being damaged and broken off. The device is provided with a center rod, and the center rod is sleeved with the spherical wearproof body; an upper limiting ring and a lower limiting ring which are fixed on the center rod are arranged at the upper side and the lower side of the wearproof body on the center rod respectively, and gaps exist between the upper limiting ring and the wearproof body and between the lower limiting ring and the wearproof body. The pumping well anti-eccentric wear device with the spherical wearproof body is long in wearproof time, and capable of preventing the pumping rod and the oil pipe from directly making contact to generate wear, prolonging the service life of the pumping rod and the oil pipe and maintaining the normal production of a pumping well.
