Abstract
The utility model relates to an anti-freezing device for the air discharge pipe of a wellhead casing which is used for an oil field. An easy freezing regulation constant pressure valve 11 and an air passing pipe 5 are arranged in sealing housings (2, 4), and the housings are provided with joints (7, 10, 1) for the inflow and the outflow of the heat source fluid medium. Because heating measures are adopted, the freezing phenomenon can not happen even in cold seasons, which ensures that the air discharge pipe is unobstructed.
Description
The utility model relates to a kind of defroster that is used for oil well muzzle pipe blowdown piping.
At present,,, still freeze phenomenon, influence the production of oil mass at low temperature moral blowdown piping because of the gas of emitting from sleeve pipe contains water though the blowdown piping that production wellhead is made up of ordinary casing vent valve, pipe on the oil field has the measure of wrapping winter protection thing; Roasting the removing of fire commonly used frozen, and may bring hidden danger thus.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, partly puts in the insulation shell that can warm oneself easily freezing on the well head sleeve pipe blowdown piping and provide a kind of, and temperature phenomenon can not occur freezing when descending, and helps the ordinary production of well.
The purpose of this utility model can reach by the following technical programs: place in the seal casinghousing easily freezing the level pressure control valve on the well head and crossing tracheae, have the heat source fluid medium to import and export joint on the housing.
The utility model compared with prior art has following effect:
Owing to taked the heating measure, the season of cold can not freezed phenomenon yet, guarantees that blowdown piping is unimpeded, helps producing.
Accompanying drawing is the utility model diagrammatic sketch.
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Shown in accompanying drawing, the production wellhead nexine is adjustable level pressure blowdown piping by the threeway 13 that is threaded, valve 12, regulate constant pressure valve 11, cross tracheae 5 and venting 9 and form.Regulate constant pressure valve 11 easily freezing, cross tracheae 5 and place in the seal casinghousing (2,4), heat source fluid medium import and export joint (7,10,1) is arranged on the housing; The housing junction can adopt clamp (3,6) to connect, and housing 2 can adopt the iron sheet welding, and pipeline heating housing 4 partly can connect with sebific duct.Above-mentioned 10 is inlet union, the 7, the 1st, and import and export; Scheming last 8 is O type seals.
Above-mentioned heating import and export (7,1) is connected in series with aboveground circulation heating pipeline.
Claims (1)
1, a kind of defroster that is used for oil well muzzle pipe blowdown piping, it is made up of the threeway that is threaded (13), valve (12), level pressure control valve (11), mistake tracheae (5) and the head (9) of giving vent to anger, it is characterized in that: regulate constant pressure valve (11) easily freezing, cross tracheae (5) and place in the seal casinghousing (2,4), have on the housing heat source fluid medium into and out of joint (7,10,1).
