Description
Technical field
The utility model is related to recover the oil（Gas）Wellhead assembly, it is specifically a kind of easy to operate, easy to maintenance and can
Reduce the oil recovery gas production wellhead of the included sucker rod blowout-prevention combination valve of labor intensity.
Background technology
In oil（Gas）During the production operation of field, sucker rod is very important component, it is the important portion of sucker rod pumping
Part, sucker rod connect into the plunger of oil well pump by box cupling, and effect is to pass to the reciprocating motion of pumping unit horsehead suspension point
Downhole pump.In order to ensure the sealing performance of sucker rod at work, it is necessary to be come using a set of entitled blowout preventer of sucker rod
Realize that this requirement, traditional way are to install a set of preventing sucker rod spray box on the top of production tree to realize to the close of sucker rod
Envelope, increases the height of production tree, improves production cost, increase the labor intensity of worker in this way.
Invention content
The purpose of this utility model is for oil（Gas）The space of installation preventing sucker rod spray box is inadequate in the production process of field, grasps
Make the excessively high drawback of trouble, cost, a kind of included sucker rod easy to operate, easy to maintenance and can reducing labor intensity is provided
The oil recovery gas production wellhead of blowout prevention combination valve.
The purpose of this utility model solves by the following technical programs：
A kind of oil recovery gas production wellhead of included sucker rod blowout-prevention combination valve, including wellhead sluice valve and the small four-way of well head, it is special
Sign is：Corresponding blowout prevention combination valve is respectively equipped in the one pair of which through-hole of the small four-way of well head, after blowout prevention combination valve
End carries corresponding control stick, realizes the sealing to sucker rod by the precession and back-out of the corresponding control stick in both sides and opens
It puts.
Corresponding seal receptacle is respectively set in the front end of the blowout prevention combination valve, and the seal receptacle for being located at sucker rod both sides can be with
Sucker rod is contacted and is closed to realize the sealing to sucker rod.
The utility model has the following advantages compared with prior art：
The utility model installs a set of blowout prevention combination valve on the ontology by the small four-way of well head in production tree, by two
The switch of side control stick controls to realize the sealing and opening to sucker rod；The blowout prevention combination valve is directly installed on the small four-way of well head
On, reduce material, saved cost, and blowout prevention combination valve is mounted on inside the small four-way of well head, has saved entire wellhead assembly
Height and space, labor intensity that is easy to operate, easy to maintenance and reducing worker, effectively save production cost improve
Production efficiency simultaneously increases economic benefit.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the oil recovery gas production wellhead of the included sucker rod blowout-prevention combination valve of the utility model；
Attached drawing 2 is the structural schematic diagram of the small four-way of well head of the utility model.
Wherein：1-wellhead sluice valve；The small four-way of 2-well heads；3-seal receptacles；4-blowout prevention combination valves；5-control sticks.
Specific implementation mode
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figs. 1-2：A kind of oil recovery gas production wellhead of included sucker rod blowout-prevention combination valve, including wellhead sluice valve 1 and well
Mouthful small four-way 2, it is characterised in that：It is respectively equipped with corresponding blowout prevention combination valve in the one pair of which through-hole of the small four-way of the well head 2
4, the rear end of blowout prevention combination valve 4 carries corresponding control stick 5, is realized by the precession and back-out of the corresponding control stick in both sides 5
Sealing and opening to sucker rod；In addition corresponding seal receptacle 3 is respectively set in the front end of blowout prevention combination valve 4, is located at sucker rod two
The seal receptacle 3 of side can be contacted and be closed with sucker rod to realize the sealing to sucker rod.
As shown in Fig. 2, when the oil recovery gas production wellhead of the included sucker rod blowout-prevention combination valve of the utility model is in use, rotation
Control stick 5, making control stick 5, side is moved inwards, and to drive seal receptacle 3, side is moved inwards, and seal receptacle 3 and sucker rod is made to contact simultaneously
Closing, you can sucker rod is sealed.
The utility model installs a set of blowout prevention combination valve 4 on the ontology by the small four-way of well head in production tree 2, by right
The switch of both sides control stick 5 controls to realize the sealing and opening to sucker rod；It is small that the blowout prevention combination valve 4 is directly installed on well head
On four-way 2, reduce material, saved cost, and blowout prevention combination valve 4 is mounted on inside the small four-way of well head 2, has saved entire well
The height of mouth device and space, labor intensity that is easy to operate, easy to maintenance and reducing worker, effectively save production cost,
It improves production efficiency and increases economic benefit.
Above example is only to illustrate the technological thought of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical solution each falls within this reality
Within the scope of novel protected；The technology that the utility model is not directed to can be realized by the prior art.
