Description
Technical field
The well mouth of oil well device of oil extraction in oil field is the utility model is related to, specifically a kind of fast-connecting type thick oil well is certainly
Dynamic control device of air.
Background technology
Oilfield rich reserves, rich hydrogen sulfide containing gas are present in oil reservoirs in the form of gas-cap gas and solution gas.
During oil mining, substantial amounts of casing gas is just formed in oil well casing, if not in time discharged gas, underground depth will be influenced
The normal work of well pump, reduces pump efficiency.To discharge gas, oil recovery work will periodically open sleeve gate and carry out putting casing gas work
Make, labor intensity increase, labor productivity reduces.
Through patent searching document, application number：200520028588.8 publication date 2006-07-26 discloses a kind of well head control
Gas recovering device, belongs to technical field of petroleum machinery, and gas-tpe fitting is threadedly coupled reducing silk head, and reducing silk head other end screw thread connects
The inlet port of one-way control valve body is connect, pressure regulation seal is housed inside its assembly, pressure regulation seal inner upper end is equipped with pressure regulation
Spring is arranged below in silk plug, pressure regulation silk plug, and sealed valve core is arranged below in spring, and seal receptacle is arranged below in sealed valve core, unidirectional control
The outlet of valve body processed is threadedly coupled discharge rubber hose coupling, the discharge rubber hose coupling other end by pressure cap connect discharge sebific duct into
Mouthful, the outlet of discharge sebific duct connects another discharge rubber hose coupling by pressure cap, is provided with hole in the middle part of tracheae outer wall, tapping passes through import
Connector connects needle valve import, aciculiform valve outlet connection outlet connector.
Patent document disclosed above in technical solution, technique effect and the technical problem of solution all with the utility model not
It is identical.
The content of the invention
The purpose of this utility model is to provide a kind of fast-connecting type thick oil well to control device of air automatically, first, solving manually to put
The problem of casing gas labor intensity is big, time-consuming effort；Second, solve because casinghead gas it is big, oil well gas lock, excitement, shake out, pump efficiency it is low
The problem of；Third, solve the problems, such as physically and mentally healthy rich in the external pollution discharging environment of stink damp, serious infringement worker.
In order to achieve the above objectives, the utility model employs following technical solution, and a kind of fast-connecting type thick oil well is automatic
Control device of air, including sleeve gate, Well head flow path pipeline, Well head flow path is used as after the silk plug dismounting on the Well head flow path pipeline
Pipeline opening, connection control gas pipeline between described sleeve pipe gate, Well head flow path pipeline opening.The control gas pipeline includes connecting successively
Hose, elbow, the ball-and-seat connect.The beginning connecting sleeve gate of the hose.The ball-and-seat connects well head by paddle
Flow pipeline opening.
The beginning of the hose is fastened on sleeve gate by taper bolt.
Compared to the prior art, the utility model has the advantages that：
Thick oil well mouth control device of air, it has paddle, and one end is connected at Well head flow path silk plug, other end connection single current
Valve, ball-and-seat pass through taper bolt connecting bend；Ball-and-seat, when casing pressure is higher than flow back pressure, valve bounce is opened, and starts to put
Gas, balances level pressure, prevents crude oil from flowing backwards；Elbow do it is in 90 °, it is convenient to be connected with flow for connection flexible pipe；Hose, oil well set
Pipe gas enter surface line passage, compressive resistance 15MPa, meanwhile, hose can solve the corrosivity of hydrogen sulfide, more durable than iron pipe
It is also convenient for；Nut, in hexagon, plays fixing bolt and connection function；Nut front end is fixing bolt, for connector sleeve pipe closer
Door.
Thick oil well mouth control device of air using the above structure, realization automatically control casing gas, without human intervention, gas
Enter flow by closed hose, securely and reliably, environmental protection standard is high, efficiently solves the risk of hydrogen sulfide poisoning, purification
Air index, promotes employee's physical and mental health.
Brief description of the drawings
Fig. 1 is the structure diagram that a kind of fast-connecting type thick oil well controls device of air automatically.
In figure：Sleeve gate 1, taper bolt 2, hose 3, elbow 4, ball-and-seat 5, paddle 6, Well head flow path pipeline opening
7。
Embodiment
Detailed description and technology contents in relation to the utility model, coordinate brief description of the drawings as follows, but attached drawing is only to refer to
With purposes of discussion, not it is used for being any limitation as the utility model.
As shown in Figure 1, a kind of fast-connecting type thick oil well controls device of air, including sleeve gate 1, Well head flow path pipe automatically
Line, Well head flow path pipeline opening 7, described sleeve pipe gate, Well head flow path are used as after the silk plug dismounting on the Well head flow path pipeline
Connection control gas pipeline between pipeline opening.The control gas pipeline includes sequentially connected hose 3, elbow 4, ball-and-seat 5.It is described soft
The beginning connecting sleeve gate of pipe.The beginning of the hose is fastened on sleeve gate by taper bolt.The single current
Valve connects Well head flow path pipeline opening by paddle 6.
It is changed into Well head flow path pipeline opening 7 in use, removing silk plug at Well head flow path silk plug, as by the heavy oil wells well
One end of mouth control device of air is connected with Well head flow path pipeline opening 7, and the other end is directly connected to casing, simple and convenient, operable
Property is strong.By means of casing pressure and the pressure difference value of wellhead back pressure, by the level pressure function of ball-and-seat, realization puts casing gas automatically.Work as casing
When gas pressure is higher than back pressure, gas jacks up valve, enters oil pipe inner cavity along hose；When the gas pressure in casing is less than
During back pressure, valve leans on gravity fall, closing passage, the crude oil in flow, it is impossible to return to casing, can prevent from flowing backwards well.
The above is only the preferred embodiment of the present invention, is not used to limit the scope of the claims of the utility model, its
He uses the equivalence changes of the utility model patent spirit, should all belong to the scope of the claims of the utility model.
