Description
Technical field
This utility model relates to oil-field oil pumper wellhead polish rod and breaks bar blowout prevention technology, specifically a kind of magnetic force noncontact
Wellhead blowout preventor.
Background technology
Oil pumping well head preventer is the most important rod-pumped well blowout hookup, widely applies at the scene of oil recovery.Its
Main Function is when oil well occurs disconnected bar, and spray-proof ball ejects, at the effect lower seal well head of bottom pressure, reaches the mesh of blowout prevention
's.Preventer structure is mainly in the way of spray-proof ball directly contacts with polished rod at present, and when polished rod break bar, spray-proof ball is at spring bullet
Eject under power effect, sealing wellhead.Existing blowout hookup there is problems in that one is that ball directly contacts with polished rod, by currently taking out
The average jig frequency of oil machine well 4 beats/min calculating, rubs 5760 every day, and long-time production causes polished rod to wear and tear, and groove is caused in side,
Cause the not tight leakage of oil of wellhead sealing, bring difficulty to production management, a polished rod need to be changed the most every year.Two is to cause spray-proof ball
Abrasion, life-time service, spray-proof ball abrasion after, when disconnected bar blowout prevention, ball is poorly sealed with ball seat, cause crude oil thorn leak, reach not
To blowout prevention effect.Three is to cause certain energy loss, and polished rod rubs for a long time with spray-proof ball, causes the waste of energy, is unfavorable for
Energy-saving and cost-reducing work.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, and devises a kind of magnetic force noncontact well
