Occurrence of accidents such as stabbing cushions and bursting pipes are prevented. The occurrence of accidents such as stabbing cushions and bursting pipes are caused by high pressure of an outlet oil transporting pipeline. The flowing well port and the steam injecting well port automatic pressure regulating oil transporting device comprises an oil nozzle sleeve. A plug and an oil nozzle are arranged in an oil nozzle sleeve body. A pressure reducing valve is installed in a liquid inlet passageway of the oil nozzle sleeve. A needle valve, a spring guiding valve and a ball valve are connected in series on a controlling pipeline. One end of the controlling pipeline is communicated with the liquid inlet passageway of the oil nozzle sleeve. The needle valve is installed on the controlling pipeline. The other end of the controlling pipeline is communicated with a liquid outlet cavity of the oil nozzle sleeve. A pressure reducing valve controlling pipeline is communicated with a pressure reducing valve controlling room. The pressure reducing valve controlling pipeline is connected between the spring guiding valve and the needle valve in series. Opening and closing of a pressure reducing valve core is controlled by adjusting pressure regulating spring of the spring guiding valve Stability of outlet pressure in the process of opening flowing of the flowing well and the steam injecting well of the oil field is effectively guaranteed. Occurrence of accidents such as stabbing cushions and bursting pipes are prevented. The occurrence of accidents such as stabbing cushions and bursting pipes are caused by high pressure of the liquid outlet oil transporting pipeline.
Description
Technical field
The utility model relates to the wellhead assembly of oil field flowing well and steam injection well, particularly flowing well and steam injection well well head automatic Regulation fuel delivery device, can effectively guarantee flowing well and steam injection well open flow process middle outlet pressure stability, prevent the generation because of accidents such as thorn mat that outlet petroleum pipeline hypertonia causes, boosters.
Background technology
When beginning blowing after flowing well and the heavy oil wells steam injection, strata pressure is very high, and suitable oil nozzle control oil well production pressure reduction must be installed, and strata pressure descends gradually along with the consumption of energy, changes high pressure into low pressure production.Well-known heavy oil wells pipeline is not smooth to be very normal, and winter during open flow particularly, pipeline is in case stop up, and low-pressure line will build the pressure, and maintains an equal level with pressure before the oil nozzle.At this moment the accidents such as mat, booster are stung in very easy generation, and the oil gas of a large amount of HTHPs will be revealed, and pollution and human casualty accident that very easy generation is great are necessary to develop the automatic Regulation fuel delivery device for this reason and guarantee safety in production, cleaner production.
Summary of the invention
The purpose of this utility model provides flowing well and steam injection well well head automatic Regulation fuel delivery device, both can control the flow of oil well, can guarantee again the stable of output pressure.Behind the oil well open flow, can guarantee the liquid outlet pressure stability of open flow in the safe pressure scope, the petroleum pipeline of liquid outlet is in case stop up, and this device will automatic Regulation, cut off the highly pressurised liquid of inlet, assurance is in the safety of the liquid outlet petroleum pipeline of low-pressure state.
The technical solution of the utility model is: flowing well and steam injection well well head automatic Regulation fuel delivery device comprise resistance oil nozzle sleeve, and plug and oil nozzle are housed in the resistance oil nozzle sleeve body.In the feed liquor runner of resistance oil nozzle sleeve, reducing valve is housed, the needle-valve of contacting on the control piper, spring pilot valve and ball valve; An end that control piper is equipped with needle-valve is communicated with the feed liquor runner of resistance oil nozzle sleeve, and the other end is communicated with the sap cavity that goes out of resistance oil nozzle sleeve, and reducing valve control piper in parallel is communicated with the reducing valve control room on the control piper between spring pilot valve and the needle-valve.The pressure spring of regulating spring pilot valve, the keying of control relief pressure valve cartridge.
Compared with prior art, the utlity model has following useful effect: the reducing valve of the utility model design is installed in the feed liquor runner of resistance oil nozzle sleeve, control the pressure of liquid outlet by adjusting the spring pilot valve, can effectively guarantee the stable of liquid outlet pressure in flowing well or the steam injection well open flow process, prevent the generation because of accidents such as thorn mat that liquid outlet petroleum pipeline hypertonia causes, boosters.Avoid great environment pollution and human casualty accident occur, have obvious economic benefit and social benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail.Referring to accompanying drawing, flowing well and steam injection well well head automatic Regulation fuel delivery device comprise resistance oil nozzle sleeve, and plug 2 and oil nozzle 3 are housed in resistance oil nozzle sleeve body 1.In the feed liquor runner of resistance oil nozzle sleeve, reducing valve is housed, the needle-valve 8 of contacting on the control piper 9, spring pilot valve 7 and ball valve 6; An end that control piper 9 is equipped with needle-valve 8 is communicated with the feed liquor runner of resistance oil nozzle sleeve, and the other end is communicated with the sap cavity that goes out of resistance oil nozzle sleeve, and reducing valve control piper in parallel is communicated with reducing valve control room 12 on the control piper 9 between spring pilot valve 7 and the needle-valve 8.Reducing valve comprises relief pressure valve cartridge 4, spring and reducing valve plug 5, and mounting spring between relief pressure valve cartridge 4 and reducing valve plug 5 consists of reducing valve control room 12.The feed liquor runner of resistance oil nozzle sleeve is Z-shaped, and relief pressure valve cartridge 4 is loaded in the Z-shaped feed liquor runner, and its underpart cone cooperates with the place of curving of Z-shaped feed liquor runner.The outer end of the Z-shaped feed liquor runner of resistance oil nozzle sleeve is that inlet 10 is connected with wellhead flowline; The side that the liquid outlet 11 of resistance oil nozzle sleeve is located at resistance oil nozzle sleeve body 1 with go out sap cavity and be communicated with and be connected with the petroleum pipeline of oil well.
When control piper 9 comes liquid from inlet 10, flow through needle-valve 8 and enter reducing valve control room 12, the pressure of liquid outlet 11 is by control piper 9 and be in the ball valve 6 of often opening and be applied on the spring pilot valve 7; When liquid outlet 11 pressure were higher than the setting value of spring pilot valve 7, spring pilot valve 7 cut out.Reducing valve control room 12 internal cause pressure raise and have closed relief pressure valve cartridge 4 at this moment, and the pressure of liquid outlet 11 no longer raises.
When liquid outlet 11 pressure dropped to the pressure of spring pilot valve 7 settings, spring pilot valve 7 was opened, and reducing valve control room 12 is to oil nozzle 3 discharge opeings.Because the discharge capacity of spring pilot valve 7 is greater than the feed liquor amount of needle-valve 8, the pressure drop in reducing valve control room 12 opens relief pressure valve cartridge 4 from the pressure of inlet 10.Under the stable state, reducing valve control room 12 feed liquors, discharge opeing are identical, and the aperture of relief pressure valve cartridge 4 is constant, and the pressure of liquid outlet 11 is constant.
