Abstract
The utility model relates to a hydraulic thread-off preventing shock absorber, which comprises an upper joint, a lower joint, a liquid cylinder and a centralizing sleeve, wherein an oil inlet hole and an oil outlet hole are arranged on the liquid cylinder, a piston rod is arranged in the liquid cylinder and the exterior of the piston rod is provided with the centralizing sleeve. The utility model is connected with a sucker rod by the upper and the lower joints, when the sucker rod moves upwards and downwards, the piston rod displaces in the axial direction following the sucker rod, and meanwhile, because of the action of the oil inlet hole and the oil discharging hole on the liquid cylinder, the stroke resistance is reduced, the utility model has a buffering function and a shock absorbing function and the sucker rod is prevented from being fractured. A nylon centralizing sleeve not only has a centralizing function, but also is provided with a helical groove, and meanwhile, the nylon centralizing sleeve has the function of helping pumping. The utility model has the advantages of novel design, reasonable and compact structure and high strength, the utility model can effectively prevent the bending distortion and tripping of an oil pipe which are caused by hole deviation or a dogleg phenomenon, the utility model can effectively reduce produced torque stress and impact force simultaneously, the utility model reduces the thread-off frequency of the sucker rod, the repair free period of an oil well is extended, the production time rate of the oil well is improved and the yield of the oil well is increased.
Description
Technical field
The utility model relates to the anti-breaking damper that takes off of a kind of sucker rod anti-breaking and disconnecting device, particularly hydraulic pressure.
Background technology
It is present most widely used oil production method that machinery has bar to recover the oil, and reaches hundreds of rice to the sucker rod of several kms and fuses by box cupling.Mining type causes rod collar and the serious sliding friction of tube inner wall generation in oil pumping process as long as adopt inclined shaft technology, thereby has increased suspending point loading and axial stress generation dropout stopping production accident.Simultaneously, because the specific (special) requirements of oil pumping technology makes sucker rod move back and forth, and the vibratory impulse stress that produces cause sucker rod that a large amount of phenomenon of ruptures take place, thereby anti-breaking taking off is the emphasis difficult problem of oil extraction operation.The anti-breaking device that takes off that use at present domestic each oil field is all because of being subjected to the sucker rod spatial constraints, and often insufficient strength is not that bearing steel ball is crushed, and is exactly that roofbolt is meticulous and rupture; And the under-well bi-directional damper causes tool failures because the fluctuating load of oil well pump makes more easy fracture of butterfly spring.
The utility model content
The utility model provides a kind of and collects damping, anti-breakingly takes off, sets upright the hydraulic pressure anticreep damper that function is an one, plays anticreep, cushioning effect, reduces the stroke resistance, prevents rod broken.
Technology settling mode of the present utility model is: the anti-breaking damper that takes off of hydraulic pressure, comprise top connection, lower contact, fluid cylinder, supporting positive cover, and lower contact is connected with fluid cylinder, fluid cylinder is provided with the turnover oilhole, be provided with piston rod in the fluid cylinder, the piston rod other end is located in the top connection, and piston rod is provided with supporting positive cover outward.
Described supporting positive cover is provided with helicla flute.
The utility model is connected with sucker rod by upper and lower joint, and piston rod is with sucker rod axial displacement, simultaneously because the effect of the enterprising outage of fluid cylinder in commutation process, when sucker rod moves up and down, reduce the stroke resistance, play the bumper and absorbing shock effect, prevent rod broken.The nylon supporting positive cover not only plays centralizing function, and supporting positive cover is provided with helicla flute, plays the effect of taking out that helps simultaneously.The utility model modern design, rational in infrastructure, compact, intensity is big, can effectively prevent to cause the tubing bending distortion and thread off because of hole deviation or dog-leg, also can overcome moment of torsion stress and the impact force that is produced effectively simultaneously, reduce the rod parting number of times, prolong oil well repair free period, rate when improving oil well production increases oil well output.

The specific embodiment
The anti-breaking damper that takes off of hydraulic pressure, comprise top connection 1, lower contact 11, fluid cylinder 7, supporting positive cover 4, lower contact 11 is connected by hold-down screw 10 with fluid cylinder 7, be provided with sealing ring 9 between lower contact 9 and the fluid cylinder 6, fluid cylinder 7 is provided with turnover oilhole 8,12, is provided with piston rod 6 in the fluid cylinder 7, and piston rod 6 other ends are threaded with top connection 1, piston rod 6 is provided with pad 2 and clamping cap 3 with top connection 1 link, the piston rod 5 outer supporting positive covers 4 that are provided with.Supporting positive cover 4 is provided with helicla flute 5.The utility model is connected with sucker rod, when sucker rod moves up and down, drive piston rod 6 motions, piston rod 6 extruding fluid cylinders 7 inner fluids are discharged the effect of playing damping from oilhole 8,12, prevent rod broken, owing to be full of crude oil in the fluid cylinder 7, fluid enters in the fluid cylinder 7 from other end oilhole 12,8 simultaneously, but the stroke resistance of fluid cylinder 7 bidirectional buffering sucker rods prevents rod broken.Supporting positive cover 4 can prevent the piston rod 6 collision boreholes wall and make rod broken that the helicla flute 5 on the supporting positive cover 4 plays the effect of taking out that helps simultaneously.
