Description
Technical field:
The utility model relates to field of oil field oil extraction, particularly a kind of oil pumping machine well head linkage.
Background technology:
With wellhead assembly many employings electric device on current oil field, what have also needs kill-job, increases cost aborning, in downhole operations difficulty, simultaneously because design and operate cumbersome, also there is the problems such as waste in material resources with on the time.
Utility model content:
In order to solve Problems existing in background technology, the utility model provides a kind of oil pumping machine well head linkage, and this device has the features such as structure is simple, easy to operate, result of use is good, low cost of manufacture, safe and reliable, maintenance cost is low.
The technical solution of the utility model is: this oil pumping machine well head linkage comprises big four body, big four body underrun bolt is fixedly connected with lower flange, large ring gasket is provided with between big four body bottom surface and lower flange, big four body upper surface is fixedly connected with upper flange by bolt, each port of export of big four body is fixedly connected with valve for guarding against theft by bolt and antitheft deck, the port of export of valve for guarding against theft is provided with clip, between big four body exit end face and the end face of valve for guarding against theft, little ring gasket is installed, hanger is provided with in big four body central hole, hanger is fixed by jackscrew, hanger top excircle is male cone (strobilus masculinus), the big four inner body wall touched with the conical surface is and its inner conical surface coincide, " O " RunddichtringO is provided with between the conical surface and inner conical surface.
The utility model has following beneficial effect: this type wellhead connection device solve wellhead assembly design and complicated operation, this device simplify well head.This device is placed on production wellhead, is realized the pipe network of connecting well inner oil tube and produced on-site by this device, wellhead connection device primarily of big four, built-in boll-weevil hanger, the compositions such as upper and lower flange, valve, clip.Device inside has boll-weevil hanger can hang the oil pipe of whole mouth oil well, end adopts clip can be connected fast with on-the-spot production pipe network, can crude oil (medium) exports to pipe network in control well uninterrupted by the valve regulated of device top and both sides, this device has fast sealing function simultaneously, and the main conical surface of boll-weevil hanger that relies on does hoop sealing.This device has the features such as structure is simple, low cost of manufacture, safe and reliable, maintenance cost is low.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
In figure 1, upper flange; 2, jackscrew; 3, lower flange; 4, large ring gasket; 5, big four body; 6, clip; 7, valve for guarding against theft; 8, antitheft deck; 9, little ring gasket; 10, " O " RunddichtringO; 11, hanger; 12, male cone (strobilus masculinus).
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this oil pumping machine well head linkage, comprise big four body 5, big four body 5 underrun bolt is fixedly connected with lower flange 3, large ring gasket 4 is provided with between big four body 5 bottom surface and lower flange 3, big four body 5 upper surface is fixedly connected with upper flange 1 by bolt, each port of export of big four body 5 is fixedly connected with valve for guarding against theft 7 by bolt and antitheft deck 8, valve for guarding against theft 7 can crude oil (medium) exports to pipe network in control well uninterrupted, the port of export of valve for guarding against theft 7 is provided with clip 6, can be connected fast with on-the-spot production pipe network by clip 6, little ring gasket 9 is installed between the end face of big four body 5 exit end face and valve for guarding against theft 7, hanger 11 is provided with in big four body 5 centre bore, hanger 11 is fixed by jackscrew 2 and big four body 5, hanger 11 top excircle is male cone (strobilus masculinus) 12, big four body 5 inwall touched with male cone (strobilus masculinus) 12 is and its inner conical surface coincide, this conical surface seal has good sealing effectiveness, " O " RunddichtringO 10 is provided with between male cone (strobilus masculinus) 12 and inner conical surface.Hanger 11 supports all oil pipes of well head.
This device is placed on production wellhead, the pipe network of connecting well inner oil tube and produced on-site is realized by this device, sealed by hanger male cone (strobilus masculinus) and big four main body inner conical surface, during work, oil flows away from wellhead connection device two ends or upper end, this device can carry out mechanically actuated by connection device, Electronic control is not needed to oil well, simultaneously operationally can continuous operation, there is the features such as structure is simple, easy to operate, result of use is good, low cost of manufacture, safe and reliable, maintenance cost is low.
This device can support larger well head pressure in intensity, cone structure is had in big four body, hanger is laid in cone structure, hanger microcephaly is to transferring in big four body, ensure that big four inner sealing surface effectively contacts with the hanger external seal conical surface, hanger adopts conical surface sealing structure, can reach the object of sealing, hanger design simultaneously can holding capacity be F=686000N, and the weight of 3000m oil pipe is 271266N.
Pressure test after device installation: device is put in the test well of pressure chamber, by adopting clean water medium, test pressure adopts 42MPa, pressurize 5 minutes, continuous 2 no seepage and no leakages; Do leakage test more afterwards, device experiment pressure is adopted 21MPa, pressurize 3 minutes, continuous 2 no seepage and no leakages.
During onsite application, bottom of device be connected with the well head base at scene and use bolton, the clip of both sides being connected with on-the-spot pipeline, valve is adjusted to closed condition, in well, oil pipe is played on the top of device, tighten jackscrew after complete under oil pipe, open both sides valve, upper flange is set up, the valve on top is installed simultaneously and fastening, during use, be connected (used time) by the clip on top with pipeline, adjusting device two ends valve is to opening, start working in both sides, oil flows away from both sides.
