Abstract
The utility model discloses a blowout control connecting-tripping device which comprises a central rod, a clamp jaw, a spring A, a spring B, a supporting sleeve, a lock sleeve, a sealed working barrel and a butt-joint jaw, and is characterized in that the lock sleeve is provided with sealed outer-cone steps which are contacted with inner-cone steps of the sealed working barrel; a drive pin sliding hole is arranged on the inner side of the sealed outer-cone steps of the lock sleeve; the back part of the lock sleeve is movably assembled with a drive sleeve; a wave-shaped spring is assembled between the back end of the lock sleeve and the drive sleeve; the drive sleeve is fixedly connected with the drive pin which penetrates through the sliding hole; the outer end of the drive pin is connected with a blowout control sliding sleeve; and the drive sleeve is provided with an oil draining hole. The blowout control connecting-tripping device has the advantages that when in workover operation, the blowout control connecting-tripping device can release pressure quickly, and can be easily butted, not only can prevent crude oil from ejecting out on floor around the wellhead, thus avoiding environment pollution and saving energy, but also saves time and resources, and is applicable to operation of oil wells with different pressure.
Description
Technical field:
The utility model belongs to a kind of a kind of downhole tool of oil field operation, and particularly a kind of blowout-prevention connecting-tripping device can be accomplished when workover treatment, prevents crude oil ejection well head ground, causes environment pollution.Thereby energy conservation, accomplish green operation.
Background technology
The oil field is when workover treatment, for preventing crude oil ejection well head ground, adopt blowout-prevention connecting-tripping device to carry out operation now, but there is following deficiency in existing blowout-prevention connecting-tripping device: produce high pressure between seal operation tube and oil well pump, the descending difficulty of lock tube during butt joint, thereby dock and can not carry out smoothly, just need adding delays unloading adds hydraulic pressure in well, center-pole released from the seal operation tube dock again, lose time and resource.
The utility model content
The purpose of this utility model provides a kind of blowout-prevention connecting-tripping device, can accomplish when workover treatment, can prevent that crude oil from spraying well head ground and causing environment pollution, energy conservation, and butt joint is simultaneously saved time and resource easily.
The technical scheme that the utility model provides is as follows: it comprises center-pole, claw, spring A, spring B, support set, lock tube, seal operation tube and butt joint pawl, it is characterized in that: lock tube is provided with the contacted sealing outer cone of the inner cone step step with the seal operation tube, sealing outer cone step inboard at lock tube has the trundle slide opening, in the movable assembling in the rear portion of lock tube drive sleeve, assembling waveform spring between the rear end of lock tube and the drive sleeve, the affixed trundle that passes slide opening on the drive sleeve, the outer end of trundle connects the blowout prevention sliding sleeve, has the draining hole on drive sleeve.
Above-mentioned lock tube endoporus is provided with inner conical surface, and the butt end of butt joint pawl is provided with the male cone (strobilus masculinus) that matches.
Advantage of the present utility model: when workover treatment, can quick pressure releasing achieve a butt joint, can prevent that crude oil from spraying well head ground and causing environment pollution, energy conservation is saved time and resource simultaneously.Can adapt to the oil well operation that different wells are pressed.

The specific embodiment
See Fig. 1-5; concrete structure is as follows: comprise and adopt following prior art structure: fixing assembling claw 2 on center-pole 1; center-pole 1 outer setting seal operation tube 12; on center-pole 1, also assemble support set 4 and lock tube 7; between claw 2 and the support set 4, assemble spring (A) 3, spring (B) 5 respectively between support set 4 and the lock tube 7, protective sleeve 6 is set in spring 5 inboards.The inboard of seal operation tube 12 is provided with sealing inner cone step.Butt joint pawl 16 and positioning joint 17 are set simultaneously.Improved technical essential is as follows: lock tube 7 is provided with the outer cone step that contacts with the inner cone step of seal operation tube, outer cone step inboard at lock tube 7 has trundle slide opening 18, in the movable assembling in the rear portion of lock tube 7 drive sleeve 10, assembling waveform spring 11 between the rear end of lock tube and the drive sleeve, the affixed trundle 9 that passes slide opening 18 on the drive sleeve 10, the outer end of trundle 9 connects blowout prevention sliding sleeve 8.Have circumferentially uniform draining hole 14 (see figure 5)s on drive sleeve 10, draining hole 14 is double totally 8.At lock tube 7 endoporus inner conical surface 13 is set, the butt end of butt joint pawl 16 is provided with the male cone (strobilus masculinus) 15 that matches.
Operating principle:
Seal operation tube 12 is connected with oil pipe by screw thread, and positioning joint 17 is connected with sucker rod.
On-off connector docking operation: because blowout-prevention connecting-tripping device is connected with oil well pump, in secondary operation, after butt joint pawl 16 is thrown off, because the reasons in structure of oil well pump, thereby oil well pump to seal operation tube 12 inner cone steps with form an airtight pressure chamber below lock tube 7 outer cone steps contact, thereby when butt joint pawl 16 docks with center-pole 1, cause difficulty.So the quick pressure releasing device is housed on lock tube 7.
Quick pressure releasing apparatus structure and work are as follows: when butt joint pawl 16 docks with center-pole 1, the drive sleeve 10 that waveform spring 11 at first will be housed is depressed, the fixing trundle 9 in drive sleeve below slides in lock tube long slide opening 18, driving blowout prevention sliding sleeve 8 moves down, open in draining hole 14, promptly open pressure chamber and outside passage, pressure oil releases, thereby butt joint pawl 16 docks smoothly with center-pole 1.Drive sleeve 10 under waveform spring 11 effect with support set 4 repositions.
See Fig. 4, butt joint pawl 16 continues to press down, and the step of annular conical surface enters in the conical ring groove 19 of center-pole 1 in the butt joint pawl 16, and the inner conical surface 13 of lock tube 7 closely cooperates with the male cone (strobilus masculinus) 15 that docks pawl 16.Prolonged the application life of disjointed device.
