Abstract
The utility model discloses a shock-damping dropping resisting device for the sucker rod, and the utility model belongs to the technical field of the oil well production of the oil field in the oil industry, and the utility model is a complete set mechanical device for the oil well downhole pump. The stress of the sucker rod down the well of the mechanical sucker well on the work is variable. The sucker rod in the well is subject to the function of various force to generate elongation, compression, twisting, and even vibration. The accident of the abruption or tripping for the sucker rod can be caused. The utility model is a device which is used for reducing the vibration of the sucker rod of the oil well pump and preventing the sucker rod from tripping. The utility model is connected to the sucker rod, and the utility model performs the function of turning joint. A hydraulic piston cylinder body is designed on the utility model. Utilizing the principle of the hydraulic buffer function, the vibration of the sucker rod is reduced, and the crest value of the instantaneous stress is reduced, and the piston and the cylinder body can be freely rotated oppositely. The shackle torque force produced in the work of the sucker rod is eliminated. The problems that on the work the sucker rod generatesabruption and tripping are solved, and the working time of the oil well oil well pump down the well is prolonged.
Description
The utility model title: sucker rod damping anti-dropping device.
Technical field: the utility model belongs to the technical field of the oil well production in oil field in the petroleum industry.
Background technology: when the oil pumping of oilfield machinery is produced, the ground oil pumper drives the downhole pump oil pumping by sucker rod, in the work, sucker rod is done and is pumped, and sucker rod is subjected to the effect of various power and produces elongation, compression, twisting even vibrations in well, can cause rod broken or dropout, fall in the well, had a strong impact on ordinary production, increased recondition expense, brought economic loss to the oil field.
At present The field is sucker rod damper and sucker rod anti-dropping device, acts on singlely, and a bite well need be used sucker rod damper and sucker rod anti-dropping device, cost height simultaneously.The utility model reduces the vibrations of well rod by special frame for movement realization and prevents the double action of its dropout.Design has a hydraulic piston cylinder body on it, piston is back and forth movable in cylinder body during work, plunger shaft sucks or discharges the liquid in the oil well, produce hydraulically-damped effect, can reduce the vibrations of sucker rod, and piston and cylinder body can rotate relatively freely, eliminate the shackle torsion that produces in the sucker rod work, solved sucker rod and occurred fracture and dropout problem at work, prolonged the working time of oil-well pump of oil well in the down-hole.
Summary of the invention: the utility model is a kind of device that oil field pumping well prevents down-hole rod broken and dropout that is used for.By the sucker rod damping anti-dropping device that piston rod, piston, cylinder body are formed, its frame for movement is that piston rod one end passes the cylinder base hole and links to each other by screw thread with piston, and position, cylinder body two has liquid flow hole.
The specific embodiment: the utility model is connected on the sucker rod of pumpingh well downhole pump top 10-30m, pump with sucker rod during work, it is back and forth movable in cylinder body to drive piston, plunger shaft sucks or discharges the liquid in the oil well, produce hydraulically-damped effect, reduce the vibrations of sucker rod, piston and cylinder body can rotate relatively freely, eliminated the shackle torsion that produces in the sucker rod motion, solved sucker rod and occur the accident that ruptures and thread off at work.
Accompanying drawing is an accompanying drawing of the present utility model.
Description of drawings:
In conjunction with the accompanying drawings example of the present utility model is further described: accompanying drawing is the schematic diagram of sucker rod damping anti-dropping device.Piston rod (1) one end is the sucker rod box, and the other end links to each other by screw thread with piston (2), and piston rod (3) one ends are sucker rod pin threads, and position, cylinder body two has liquid flow hole.Sucker rod damping anti-dropping device is connected on the sucker rod of downhole pump top 10-30m, above piston rod (1) is in, below cylinder body (3) is in, sucker rod pumps and drives piston (2) back and forth activity in cylinder body (3) during work, plunger shaft sucks or discharges the liquid in the oil well, produce hydraulically-damped effect, reduce the vibrations of sucker rod, reduce the moment peak stress, and piston (2) can rotate relatively freely with cylinder body (3), eliminated the torsion of sucker rod, solved sucker rod and occur the accident that ruptures and thread off at work.
Claims (2)
1. sucker rod damping anti-dropping device of forming by piston rod, piston, cylinder body, it is characterized in that piston rod one end is the sucker rod box, the other end passes the cylinder base hole and links to each other by screw thread with piston, cylinder body one end is the sucker rod pin thread, its position, two has liquid flow hole, piston is back and forth movable in cylinder body during work, and plunger shaft sucks or discharge the liquid in the oil well.
2. sucker rod damping anti-dropping device according to claim 1 is characterized in that piston and cylinder body leave the gap, can rotate relatively freely.
