Abstract
The utility model discloses a track rotation type bleeder, it includes center tube, top connection, sliding sleeve and sealing member, has installed draining mechanism and righting device on the center tube. The righting device moves on a track on the surface of the central tube, and the oil drainage mechanism is pushed to open the oil drainage hole so as to achieve the purpose of oil drainage. The oil drain device has the advantages of simple structure, convenient operation, sealing and oil draining safety and reliability.
Description
The utility model relates to the oil exploitation downhole tool, relates in particular to a kind of track rotary bleeder.
At present, the bleeder that generally use at the oil exploitation scene is mainly based on the inner sliding sleeve formula, and its structure is joint, spring, claw, shear pin, pin, packing ring, box cupling, sleeve valve, sealing ring, pipe nipple.But to drive special box cupling by sucker rod when it exists draining and open sleeve valve draining, or trip out and drop into metal bar bump sliding sleeve behind the sucker rod and open draining hole draining, shortcoming that then can't draining when sucker rod can not trip out.In addition, also exist because of adopting shift sleeve structure, interior latus rectum is little, the unreliable deficiency that waits of draining work during lower sucker rod.
The purpose of this invention is to provide a kind of track rotary bleeder, it can finish draining work flexibly effectively, and this bleeder adopts outer sliding sleeve rail mounted structure, and interior latus rectum is big, sealing, and reliable, draining is flexible, and is easy to operate.
The purpose of this utility model reaches like this:
The erection device that comprises the draining mechanism of top connection, seal, screw, protective sleeve, interstage sleeve, spring, sliding sleeve, steel ball and lock tube and comprise upper pressing cap, lower pressing cap, cell body, brake pad, spring, swivel becket, pin and screw is installed on central tube.
The purpose of this utility model can also reach by following measure:
The track that has erection device to move on the central tube thereon, its track are a groove shape structure at the external surface of central tube.The pin of erection device moves in orbit.On the cell body of erection device, at interval groove is set, it is embedded with spring and metal strip brake pad.This groove is provided with along axis direction on the cell body surface.One end external surface of sliding sleeve has circular trough, and the other end has the limited step in opening and closing draining hole.The middle part is porose.Steel ball is loaded in the hole.The sliding sleeve inner surface has the circular trough that discharges steel ball, the interior step that an end matches with sliding sleeve in addition.
The drawing of accompanying drawing is described as follows:
Fig. 1 looks sectional view for the utility model example structure master:
Fig. 2 is the track expanded view on the utility model central tube:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the top connection 1 of draining mechanism is connected with central tube 21, and sliding sleeve 8 is contained on the central tube 21; the tapping of sliding sleeve 8 steel ball 9 of packing into, lock tube 10 is contained on the sliding sleeve 8, mounting spring 7 and interstage sleeve 5 on it; protective sleeve 4 one ends are enclosed within outside spring 7 and the interstage sleeve 5, and the other end links to each other with top connection 1.Seal 2,11 center seal pipes 21 and top connection 1 and sliding sleeve 8, backing-up screw 3 is screwed on top connection 1, protective sleeve 4 and the central tube 21, and screw 6 is screwed on interstage sleeve 5 and the lock tube 10.
The upper pressing cap 12 and the cell body 13 of erection device are installed on the central tube 21.Brake pad 15, spring 16 are packed on the cell body 13.Lower pressing cap 17 is connected with cell body 13, and swivel becket 19, pin 20 and spring 18 are installed in the inner chamber between central tube 21 and the lower pressing cap 17 successively, and pin 20 just in time is in the track of center surface, the movement locus of restriction erection device.Screw 14 is screwed on upper pressing cap 12 and the cell body 13.
When the rail mounted bleeder was gone into the well, pin 20 moved in short track, and erection device can not be contacted with lock tube 10, has guaranteed the sealing in draining hole, makes bleeder be lowered to the precalculated position smoothly.When the needs draining, on carry the oil pipe certain altitude, tubing string is transferred on rotation pipeline limit, limit, makes pin 20 enter long track, erection device rises, it is up to promote lock tube 10, and compression spring 7 discharges steel ball 9, it is up together to promote sliding sleeve 8, open the draining hole, simultaneously lock tube 10 and sliding sleeve 8 are locked in an end of central tube 21 together again, and the draining hole is draining for a long time just.On carry oil pipe and trip out bleeder.
The utility model is compared with existing technology, has the following advantages:
1, adopt track and outer sliding sleeve structure, simple to operate, draining is easily convenient, can need arbitrarily constantly draining;
2, the inner edge footpath is big, can be by the lower corresponding oil well pump of oil pipe requirement;
3, sliding sleeve adopts steel ball structure, and it is little to promote the required strength of sliding sleeve draining, stable, safe and reliable.
