Description
Technical field
Oil field pumping well wellhead equipment is the utility model is related to, specifically a kind of polished rod sealer.
Background technology
In pumpingh well oil pumping, oil pumper drives upper and lower move back and forth of polished rod, sucker rod, oil well pump to realize oil pumping, polished rod
The upper and lower reciprocating motion in sealer, by forming dynamic sealing between packing and polished rod.In production, because oil pumper is installed
The reasons such as error, oil-pump base, well head pipeline commissioning, pumping unit hanging point is caused to produce angle displacement and level with well head center
Displacement, well head is misaligned with polished rod, cause packing eccentric wear, load increase, power consumption is high, while seal failure, well head oil leak, separately
Outside, because oil pumping polish rod longtime running is acted on by alternate load, polished rod fatigue fracture is fallen into well, causes to have during blowout phenomenon
Occur, not only cause crude oil to lose, and pollute environment, influence the horizontal raising of field management.Thus, the well head of pumpingh well is close
Envelope, centering, disconnected bar blowout prevention be three big technical barriers of field management, especially heavy oil wells, note polymer displacement oil well wellhead sealing difficulty more
Greatly.
At present, polished rod sealer species is more, and conventional polished rod sealer is by pressure cap compression packing axial direction, radial direction deformation
Reach sealing, when caoutchouc elasticity is compressed to the limit, sealing function is just lost, when changing packing, it is necessary to close both sides rubber lock

A kind of energy-saving anti-theft bias-adjusting polish rod sealer, the patent No.：It is 200420097041.9 uncomfortable using nylon spray-proof ball
Yi Gaowenrecaijing.A kind of magnetic supercharging polished rod sealer announced, application number：201610372660.1 the magnetic fluid of use
Sealing, actual magnet fluid sealing requirement work under the dustfree environment of precision, are not suitable for oil field field production scene, meanwhile,
When magnetic supercharging polished rod sealer has handling top, bottom is unable to temporary sealing, does not possess disconnected bar blowout prevention function.Cause
And prior art still can not preferably solve the problems, such as the wellhead sealing of pumpingh well, centering, disconnected bar blowout prevention.
