Abstract
A kind of pumpingh well threeway polished rod inhibition preventer, comprising: body (1), clip (2), blowout prevention plate (3)); It is characterized in that: the body (1) of described pumpingh well threeway polished rod inhibition preventer is tubular type threeway, side branches is bend pipe structure, three ends are equipped with hoop (2), the end face of hoop (2) is equipped with trapezoidal steel ring slot (A), the inner end that side leads to is provided with blowout prevention plate (3), hinged by hinge (301) with the top of body (1).The utility model is applicable to oilfield produced fluid containing CO2, H
2the pumpingh well of the corrosive mediums such as S; resulting fluid is little by the impact force of elbow to polished rod; make wellhead polish rod produce impingment corrosion to alleviate; magnadure pipe reaches the effect of protection polished rod in well liquid by sacrificial anode; extend the application life of polished rod, prevent well head leakage of oil, and there is polished rod break blowout prevention effect; prevent the pollution of the environment, improve the daily management level of pumpingh well.
Description
Technical field
the utility model relates to oil field pumping well polished rod anticorrosion and disconnected bar blowout prevention technology, specifically a kind of pumpingh well threeway polished rod inhibition preventer.
Background technology
at present, in oil field pumping well manufacturing process, along with the continuous exploitation in oil field, well water rises year by year.The corrosive mediums such as CO2, H2S in formation water are on the rise to pit shaft metal equipment corrosion, and conventional resulting fluid is maximum in the impact force of crook, right angle to polished rod, make wellhead polish rod produce impingment corrosion, the lost of life.From on-the-spot corrosion condition, bare rod corrosion position focuses mostly in bottom.Bare rod corrosion causes well head leakage of oil, polished rod break, causes environment pollution, cost increase, has had a strong impact on the daily management of oil well.
Summary of the invention
the purpose of this utility model is exactly for above-mentioned weak point, designs a kind of pumpingh well threeway polished rod inhibition preventer.
the purpose of this utility model is realized by following technical proposals:
the utility model comprises: body, clip, blowout prevention plate.The body of described pumpingh well threeway polished rod inhibition preventer is tubular type threeway, and side branches is bend pipe structure, and three ends are equipped with hoop, and the end face of hoop is equipped with trapezoidal steel ring slot, and the inner end that side leads to is provided with blowout prevention plate.
hinge is passed through on blowout prevention plate in above-mentioned pumpingh well threeway polished rod inhibition preventer and the top of body.
body in above-mentioned pumpingh well threeway polished rod inhibition preventer is manufactured by magnesium-aluminium alloy material.
the beneficial effects of the utility model are: be applicable to oilfield produced fluid containing CO2, H
2
the pumpingh well of the corrosive mediums such as S; resulting fluid is little by the impact force of elbow to polished rod; make wellhead polish rod produce impingment corrosion to alleviate; magnadure pipe forms galvanic cell with polished rod in well liquid; magnadure chemical property is active; it is corroded gradually as anode; and polished rod current potential of comparing is higher as negative electrode; namely the effect of protection polished rod is reached by sacrificial anode; extend the application life of polished rod, prevent well head leakage of oil, and there is polished rod break blowout prevention effect; prevent the pollution of the environment, improve the daily management level of pumpingh well.
Accompanying drawing explanation
fig. 1-Ben practicality is main looks broken section structural representation.
the on-the-spot application structure schematic diagram of Fig. 2-the utility model.
in figure, 1. body, 2. hoop, 3. blowout prevention plate, 301. hinges, 4. pumpingh well threeway polished rod inhibition preventer, 5. produce gate, 6. polished rod sealer, 7. polished rod; A. steel ring slot.
Detailed description of the invention
by reference to the accompanying drawings, the utility model will be further described:
pumpingh well threeway polished rod inhibition preventer is by body 1, clip 2, and blowout prevention plate 3 forms.The body 1 of described pumpingh well threeway polished rod inhibition preventer is tubular type threeway, side branches is bend pipe structure, and three ends are equipped with hoop 2, and the end face of hoop 2 is equipped with trapezoidal steel ring slot A, the inner end that side leads to is provided with blowout prevention plate 3, and blowout prevention plate 3 is hinged by hinge 301 with the top of body 1.During use, former pumping well head threeway is laid down, load onto steel ring and pumpingh well threeway polished rod inhibition preventer 4, with polished rod sealer 6 with produce gate 5 clamp connection, opening well and making production, the object of polished rod inhibition and disconnected polish rod anti-blowout can be reached.
Claims (3)
