Description

The rotation bleeder
Technical field
The utility model is the downhole tool of oil field oil recovery usefulness, is a kind of bleeder, particularly a kind of rotation bleeder.
Background technology
Existing bleeder kind is a lot; Like one Chinese patent application 96238554.9 " a kind of split type rotation bleeder of carrying "; Its brace type is separated lock assembly and will be contacted and draining with the draining assembly when carrying oil pipe last; Will cause bleeder to open draining when running in the operation workman operate miss or the process of going into the well when new situation needs to carry oil pipe, make operation unsuccessful.Also there is the problem of above-mentioned patent in one Chinese patent application 00247456.5 " carry rotation bleeder " and for example.The operating worker operate miss is the custom that is difficult to change that itself needs the operation of carrying oil pipe and form for many years because of in the following oil pipe process, all might cause the draining of opening of this type of bleeder.One Chinese patent application 00258996.6 " slip-type rotation bleeder ", slips can not radially open, and can not be stuck on the sleeve pipe, so draining had not both made slips radially open and has been stuck on the sleeve pipe, slips can not be regained sometimes and blocks tubing string behind the draining, causes the accident.One Chinese patent application 2007200290118 " a kind of rotation bleeder " and for example; It simple in structure; But its sealing shroud (5) and interior pipe (3) are for being threaded; Because there are problems such as fouling, corrosion in the well that has, the connecting thread that causes sealing shroud (5) and interior pipe (3) easily can't get loose and can not draining.
Summary of the invention
The purpose of the utility model is to avoid the deficiency of existing bleeder, and a kind of rotation bleeder is provided, and carries the oil pipe draining in the rotation again behind the following drain line.
The purpose of the utility model is achieved in that and comprises top connection, friction mechanism, adapter sleeve, track pin, lock tube, lock ball, sealing shroud, last sealing ring, lower seal, interior pipe that top connection is connected with interior pipe top, on the interior pipe track is arranged; The track pin front end is inserted in the track on inner pipe, the lock ball groove is arranged, draining hole on the interior pipe on the interior pipe; The sealing shroud suit on inner pipe, sealing shroud covers the draining hole, installs sealing ring, lower seal between the interior Guan Shangyu sealing shroud; Last sealing ring is on the draining hole, and lower seal is under the draining hole, in the lock ball groove in a lock ball part is on the pipe; Another part of lock ball is installed in the slotted eye of sealing shroud top, makes the sealing shroud suspension on inner pipe, and the lock tube bottom covers lock ball; Release groove is arranged in the lock tube, pipe top in friction mechanism is sleeved on, the friction mechanism bottom is connected with adapter sleeve top; The adapter sleeve bottom is connected with lock tube, and adapter sleeve covers track pin, and track pin is axially gone up and moved with adapter sleeve and lock tube; Linked hole is arranged on the sealing shroud, the track on the interior pipe get on the right track groove, connection slot, lower railway groove, the groove that gets on the right track, lower railway groove are symmetrical set; Connection slot top communicates with the groove that gets on the right track, and the connection slot bottom communicates with the lower railway groove, and track pin can move to the lower railway groove from the groove that gets on the right track.
Under the sealing shroud, on the interior pipe lower thread interstage sleeve is installed.
The beneficial effect of the utility model is: the utility model draining is carried the oil pipe draining in the rotation again behind the drain line at present, and when draining can arbitrarily be controlled by manual work, need not drop into instrument and the sucker rod of opening bleeder; Do not receive the influence of rod parting, oil pipe is identical on interior pipe latus rectum and the pump, can be lowered to various kits; Thereby the scope of application is big, but and repetitive operation, therefore; The utility model reliable operation, job success ratio is high.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
Fig. 2 is the track expanded view on the part 14 among Fig. 1.
The specific embodiment
Embodiment to the utility model describes below in conjunction with accompanying drawing.
The embodiment of the utility model comprises top connection 1, friction mechanism 2, adapter sleeve 3, track pin 4, lock tube 5, lock ball 8, sealing shroud 9, goes up sealing ring 11, lower seal 13, interior pipe 14, and top connection 1 is connected with interior pipe 14 tops, on the interior pipe 14 track 7 is arranged; In the track in track pin 4 front ends are inserted on the pipe 14, on the interior pipe 14 the lock ball groove is arranged, draining hole 12 on the interior pipe 14; On the pipe 14, sealing shroud 9 covered draining hole 12, installs sealing ring 11, lower seal 13 on the interior pipe 14 and between the sealing shroud 9 in sealing shroud 9 was sleeved on; Last sealing ring 11 is on the draining hole 12, and lower seal 13 is under the draining hole 12, in the lock ball groove in lock ball 8 parts are on the pipe 14; Another part of lock ball 8 is installed in the sealing shroud 9 top slotted eyes, and sealing shroud 9 is suspended on the interior pipe 14, and lock tube 5 bottoms cover lock ball 8; Release groove 7 is arranged in the lock tube 5, pipe 14 tops in friction mechanism 2 is sleeved on, friction mechanism 2 bottoms are connected with adapter sleeve 3 tops; Adapter sleeve 3 bottoms are connected with lock tube 5, and adapter sleeve 3 covers track pin 4, and track pin 4 is axially gone up and moved with adapter sleeve 3 and lock tube 5; Linked hole 10 is arranged on the sealing shroud 9; In the track of pipe on 14 get on the right track groove 16, connection slot 17, lower railway groove 18, the groove 16 that gets on the right track, lower railway groove 18 are symmetrical set, connection slot 17 tops communicate with the groove 16 that gets on the right track; Connection slot 17 bottoms communicate with lower railway groove 18, and track pin 4 can move to lower railway groove 18 from the groove 16 that gets on the right track.Under the sealing shroud 9, interstage sleeve 15 is installed on interior pipe 14 lower thread.
Brake pad external diameter on the friction mechanism 2 can change with casing inner diameter greater than casing inner diameter, and under spring action, brake pad is close to internal surface of sleeve pipe; And produce friction between the sleeve pipe, when the needs draining, following drain line, it is 4 motionless and the groove 16 that gets on the right track is up to pin at the effect lower railway of friction mechanism 2; Make track pin 4 arrive the last initial point of the groove 16 that gets on the right track, the ground rotation pipeline and on carry oil pipe, manage 14 in promptly carrying in the rotation; Track pin 4 just moves to 18 li of lower railway grooves from the groove 16 that gets on the right track, and lock tube 5 is exercised its inner release groove 7 thereupon down and arrived lock ball 8 places simultaneously, and lock ball 8 carries out 7 li of release grooves; Sealing shroud 9 is released, and the friction that is produced by friction mechanism 2 is pushed down motionless, pipe 1 in carrying in the continuation; Sealing shroud 9 is descending, and linked hole 10 aligns with draining hole 12, and pipe 1 inner and outside UNICOM realizes draining in making.During draining, track pin 4 is in 18 li of lower railway grooves, carries oil pipe on can be arbitrarily, accomplishes other construction operation.
