State choked flow hole slot 13 can generally semicircular oblique cone groove, matched with the shape with the choker bar 5.
In one embodiment, the choked flow hole slot 13 includes fluting 131 and perforate 132, the fluting 131 with it is described
Perforate 132 is located in the relative side wall of the body 1, described after the choker bar 5 is caught in the choked flow hole slot 13 completely
The end of choker bar 5 engages with the fluting 131, seals the through hole of the body 1.When the choked flow hole slot 13 is set
After stating relative fluting 131 and perforate 132, after the fluting 131 is particularly set, it can ensure that the choker bar 5 is being caught in
During the choked flow hole slot 13 accurately in place, while the sealing of choker bar 5 and the cooperation position of choked flow hole slot 13 can be also further ensured that
Property.
In one embodiment, the locating part is plug 7, and the body 1 is fixed on by way of screwed connection
On.Specifically, the periphery of the plug 7 can be provided with screw thread, accordingly, matched silk is provided with the body 1
Button.After the plug 7 is arranged on the body 1, its can opposing body 1 move, so as to adjust the bullet of the elastic component 6
Power.For example, during the close choker bar 5, it can increase the elastic force (elastic potential energy) of the elastic component 6, when away from the resistance
When flowing block 5, it can reduce the elastic force of the elastic component 6.Wherein, the elastic component 6 is specifically as follows the form of spring, when
So, it can also be the form that other have predetermined deformability and can produce elastic force, and the application does not make specific limit herein
It is fixed.
Further, coordinate between the pull bar 8 and the plug 7 for gap, to ensure that the pull bar 8 can be relatively described
Plug 7 slides.The position that the plug 7 and the pull bar 8 coordinate is provided with seal 9, with prevent in well it is counter go out circulation fluid
Leaked out between pull bar 8 and plug 7.Specifically, the seal 9 can be O-ring seal, of the O-ring seal
Number can be multiple, such as can be 3, preferably to ensure the sealing of sealing station.
In the present embodiment, the elastic component 6 can be used for providing reset force for choker bar 5.Specifically, the elasticity
Part 6 can be the form of spring, and its one end is resisted against on the choker bar 5, and the other end is resisted against on the locating part, when described
When choker bar 5 opens the through hole, the spring is compressed, and can be applied to the reset force that the choker bar 5 moves inward.
The guillotine mechanism can also include：The catch bar 4 being fixedly connected with the slide damper 3, the catch bar 4 have
There are relative head end and tail end, the head end of the catch bar 4 is fastened in the slide damper 3, and the tail end of the catch bar 4 is worn
If cross the body 1 to extend to outside the body 1.
In the present embodiment, the bottom of body 1 is provided with circular flashboard chamber 15, for installing the slide damper 3 of annular.Annular
Slide damper 3 by the upper shackle of catch bar 4, adjust its position.
Specifically, the slide damper 3 coordinates with the gap of flashboard chamber 15, the flashboard chamber 15 and the slide damper
The seal 9 being provided between 3.Specifically, the seal 9 can be O-ring seal, the number of the O-ring seal can
Think it is multiple, such as can be 3, preferably to ensure the sealing of sealing station.
Further, the number of the guillotine mechanism is multiple to be uniformly distributed along the circumference of the body 1, so as to
It is enough to ensure seat in the tubing string energy uniform stressed on the slide damper 3.
In general, sand washing short circuit length are more than continuous sand flushing servicing unit, and top connects recycle unit (example by pipeline
Such as, during direct circulation), bottom connection sand washing oil pipe.Often punch one it is single, unloaded, rise, connect next.
During sand washing, punch one it is single after, upper lifting pipe post, bottom tubing coupling is located at slide damper more than 3.Dextrorotation pushes away
Lever 4, slide damper 3 is driven inwardly to move, until being brought into close contact with oil pipe body 1.Tubing string is transferred, makes tubing coupling seat in ring
On shape flashboard, the sand washing short circuit of this single top connection punched is unloaded, and sand washing short circuit is proposed into continuous sand flushing auxiliary dress
Put.Now, choker bar 5 ejects under the promotion of spring, sealing continuous sand flushing servicing unit central space (through hole), sand cleaning fluid
Discharged from fluid hole 14.
That is, after using choker bar 5, through hole is closed, sand cleaning fluid is following in circulating pump in the on state
It can be discharged in the presence of ring pump from fluid hole 14.Avoiding problems sand cleaning fluid after termination of pumping to fall after rise, energy sands-proof check, the same to time
The duration for connecing next single preceding circulation has been saved, the duration needed for sand washing process has been shortened, improves sand washing efficiency.Further, since
The through hole of body 1 is sealed using choker bar 5, sand cleaning fluid will not return out from well head, further, also in body 1
It is interior to be provided with O-ring seal 2, therefore sand washing operation construction environment can be optimized.
Subsequently, sand washing short circuit can be connected fastening with another oil pipe, this root oil pipe tripping in continuous sand flushing is aided in filling
In putting, pull bar 8 is pulled out, withdraws choker bar 5.Oil pipe passes through O-ring seal 2, choker bar 5 and bottom tubing coupling pair
Just tighten, lifting top oil pipe makes bottom tubing coupling and slide damper 3 separate inverse rotation catch bar 4, drives slide damper 3 outside
Motion, until all withdrawing.Transfer tubing string and continue sand washing, now sand cleaning fluid is discharged from sand washing short circuit connection pipeloop.So
Operate repeatedly, until by sand washing to precalculated position.
Herein cited any digital value all include between lower limit to higher limit with the lower value of an incremented and
The all values of upper value, the interval of at least two units between any lower value and any much higher value be present.For example, such as
Fruit elaborates that the quantity of part or the value of process variable (such as temperature, pressure, time etc.) are from 1 to 90, preferably from 20
To 80, more preferably from 30 to 70, then purpose is to illustrate that such as 15 to 85,22 are also clearly listed in the specification arrives
68th, 43 to 51,30 to 32 is equivalent.For the value less than 1, it is 0.0001,0.001,0.01,0.1 suitably to think a unit.
These are only intended to the example clearly expressed, it is believed that the numerical value enumerated between minimum and peak is possible to
