Abstract
A constant pressure gas discharge wellhead device of an oil well sleeve comprises a wellhead seal, an oil discharge tee joint, a production valve, an upper flange, a large pipe cross, a lower flange, a sleeve valve, a seal, an oil discharge tee joint, an upper flange, a large pipe cross and a lower flange which are connected in sequence from the top down. The production valve is arranged on the left side of the oil discharge tee joint, the sleeve valve is arranged on the left side of the large pipe cross, a mixing tee joint and a pressure setting valve are also included, the mixing tee joint is arranged at the end of the discharge port of the production valve, the pressure setting valve is arranged under the mixing tee joint, and the lower end of the pressure setting valve is connected with the sleeve valve. When the wellhead device is used by an oil pumping well sleeve for collecting natural gas, sleeve gas of the oil pumping well can be directly discharged onto an oil discharge pipeline so as to recycle the natural gas, theft is avoided, and influence of the natural gas inside the sleeve on the pumping effect of the oil pumping pump is avoided. Accordingly, the wellhead device has remarkable economic profits.
Description
Technical field
The utility model is the device of using on the oil well, is a kind of oil well casing constant pressure exhaust wellhead assembly.
Background technology
In oil field pumping well, all to isolate natural gas in the sleeve pipe, natural gas easy stolen molecule in sleeve pipe connects away with simple and easy pipeline, causes the wasting of resources, also occurs security incident easily.If sleeve pipe is shut, the natural gas in the sleeve pipe is not drained, and can influence the pump efficiency of oil well pump, even can cause the oil well pump gas lock and can't normally pump, and makes oil well not fuel-displaced.
Summary of the invention
The purpose of the utility model is a kind of oil well casing constant pressure exhaust wellhead assembly of design, and it can be drained into the sleeve pipe gas of pumpingh well on the flow line, avoids natural gas stolen, avoids the gas influence oil well pump pump efficiency in the sleeve pipe.
The purpose of the utility model is achieved in that and comprises wellhead sealing device, flow tee, production valve, upper flange, big four, lower flange, sleeve valve; Sealer, flow tee, upper flange, big four, lower flange are installed from top to bottom successively; The production valve is installed in the left side of flow tee; Sleeve valve is installed in the left side of big four, also comprises mixing tee, constant pressure valve, and mixing tee is installed in the port of export of producing valve; Constant pressure valve is installed under the mixing tee, and the constant pressure valve lower end is connected with sleeve valve.
The beneficial effect of the utility model is: when the utility model is used for oil-pumping well sheath collection natural gas; Can directly be drained into the sleeve pipe gas of pumpingh well on the flow line; Make natural gas obtain recycling, can be not stolen, avoid the gas influence oil well pump pump efficiency in the sleeve pipe; Therefore, the utlity model has remarkable economic efficiency.
Description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described.
Can know by figure; The embodiment of the utility model comprises wellhead sealing device 1, flow tee 2, produces valve 3, upper flange 5, big four 6, lower flange 7, sleeve valve 8, mixing tee 4, constant pressure valve 9; Sealer 1, flow tee 2, upper flange 5, big four 6, lower flange 7 are installed from top to bottom successively; Production valve 3 is installed in the left side of flow tee 2, and sleeve valve 8 is installed in the left side of big four 6, and mixing tee 4 is installed in the port of export of producing valve 3; Constant pressure valve 9 is installed under the mixing tee 4, and constant pressure valve 9 lower ends are connected with sleeve valve 8.
When casing pressure was higher than the pressure of flow line, constant pressure valve 9 was opened, and sleeve pipe gas drains into mixing tee 4 through constant pressure valve 9 and is recovered.
Adopt clamp connection between wellhead sealing device 1, flow tee 2, production valve 3, the mixing tee 4; Flow tee 2 adopts clamp connection with upper flange 5; Big four 6 adopts clamp connection with sleeve valve 8, adopts flange to connect between upper flange 5, big four 6, the lower flange 7.
