Description
Technical field
The application is related to oil extraction in oil field technical field, and in particular to a kind of multifunctional oil wellhead.
Background technology
Wellhead for production is the visual plant of oil extraction in oil field, and there are tens thousand of mouthfuls of stripper wells in China, using oil pumper and letter
Easy wellhead tree.Due to installation deviation, most of oil well oil-pumping polished rod center lines and oil well mouth center line are simultaneously misaligned, i.e., horizontal
There is eccentric throw on face.Moreover, oil pumper, in a stroke is run, it is one that the projection of horse head suspension point in the horizontal plane, which is not,
Point, but in a circle, i.e., oil pumping polish rod up and down motion track is not vertical line, but has the straight of certain angle with horizontal plane
Line.Because the two deviations cause polished rod and well head sealing packing eccentric wear.Pump load is increased, can also damage sealed packing
Cause crude oil leakage.Existing wellhead assembly is simply by oil pumping polish rod and well head centering by force, or is singly by polished rod sealer axle
Line is adjusted to inclination, thus can addition of a radial load at polished rod and sealed packing, it is impossible to the inclined of packing is completely eliminated
Mill.
Association light hydrocarbon gas be present in most of oil wells.After rod parting, oil gas will spray from polished rod hole, cause to damage
Become estranged pollution, or even lead to security incident.Existing well head without blowout hookup, also has using ball sealer blowout prevention mostly, but seals
Ball is in oil and gas leakage, without enough lateral thrusts, it is impossible to accurate closure polished rod hole, seal failure occurs.Moreover, well head is set
Standby setting height(from bottom) is limited by beam hanger for pumping machine, and independent increased preventer is without enough installing spaces.Largely with well head
Preventer can not be increased.
Some oil wells only have one-level packing_seal, need to shut down when changing packing, influence to produce.
In order to realize more oil-producings, most of oil wells are inclined shaft or horizontal well.The eccentric wear of sucker rod and oil pipe is necessarily caused, is increased
Big pumping unit load, or even cause oil pipe to destroy and change oil pipe.
The sampling valve of existing production wellhead is a common stop valve, causes the criminal robber that gently anticipates to put crude oil.
