The drainage hole 2 of drain direction obliquely is provided in the circumferential direction of the top connection 1, when the rigid lower going-into-well of this boost motor
When interior, the injection liquid in well can be entered inside main cylinder 3 by drainage hole 2.
The top connection 1 is provided centrally with through-hole, and the release link 20 is extend into after the through-hole of top connection 1
In main cylinder 3, the piston 4 is placed in main cylinder 3 and by being slidingly sealed between 3 inner wall of sealing element and main cylinder, resets
The lower end of bar 20 is against 4 upper end of piston, is provided with balance hole 6 on 3 side wall of main cylinder of 4 lower section of piston, the effect of balance hole 6 is
When 4 uplink of piston, 3 lower interior portion of main cylinder is in communication with the outside by balance hole 6, influences piston 4 by pressure, can be suitable
The uplink of benefit.
The lower end of piston 4 is connect with stopper rod 5, and the box cupling 8 is provided centrally with the through-hole that stopper rod 5 can be made to pass through, institute
The release spring 7 stated is arranged between piston 4 and box cupling 8, and piston 4 and stopper rod 5 are protected always under the elastic force effect of release spring 7
Hold upward movement tendency.5 lower part of stopper rod is provided with undergauge step, and the setting of undergauge step is to fetter stopper rod 5 for radial, makes
Stopper rod 5 cannot move up and down, and the through-hole lower part of box cupling 8 is provided with expanding structure, and 10 top of lock tube is inserted into the expansion of box cupling 8
In pore structure, the outer wall of lock tube 10 is uniformly arranged in the circumferential direction the through-hole of the indent gradient, and the quantity of through-hole is no less than 2, described
The top of ready-packaged joint 18 be sleeved on the outside of lock tube 10, the upper inner of ready-packaged joint 18 is provided with raised step, described
Steel ball 9 is mounted between the through-hole on 10 outer wall of raised step and lock tube, the raised step support force radial to steel ball 9, steel ball 9
Fraction by being against on the undergauge step of stopper rod 5 after through-hole, to hold onto stopper rod 5 is radial, the top of raised step
Be expanding structure with lower section, when raised step is subjected to displacement upward or downward, steel ball 9 will be detached from raised step to its
Radial direction is fettered and is rolled into expanding structure, so steel ball 9 will release the radial constraint of stopper rod 5.
The small holddown spring 11 is arranged between 10 lower end of lock tube and the inside bottom of ready-packaged joint 18, and described is big
Compressed spring 19 is arranged between 8 lower end of box cupling and ready-packaged joint 18, and ready-packaged joint 18 is acted in the elastic force of big holddown spring 19
Under remain downward movement tendency, opened in the middle part of the lower contact 14 there are two opposite vertical slot, the idler wheel 12 is installed
At the fluting of lower contact 14, it is provided with 123 3 high point 121, buffer point 122, low spot run channel on 12 upper semi-circle of idler wheel, rolls
It is additionally provided with release piece 16 and lower release piece 13 on wheel 12, is provided with torsional spring on upper release piece 16 and lower release piece 13, institute
The lower part for the ready-packaged joint 18 stated is mandril 17, and 17 lower end of mandril is against in the run channel of idler wheel 12.Pulling of going into the well is stifled
When filling in device, 18 lower end mandril 17 of ready-packaged joint is located at 12 high point 121 of idler wheel, and big holddown spring 19 is in compressive state.
External force is applied to release link 20 from top, piston 4 and stopper rod 5 can generate downward under the action of downward pressure
Displacement, in order to enable the undergauge step of stopper rod 5 accurately to reach the through hole of 10 outer wall of lock tube, keeps steel ball 9 again right
The advantages of stopper rod 5 is fettered, and 20 top of release link is connected with the shoulder ring for limiting 20 axial position of release link, and shoulder ring is arranged
Also residing in will not make release spring 7 be compressed to extreme position, be conducive to extend the service life of release spring 7.
Go into the well pulling disabler when, top connection 1 is connected with launch-work device, at this point, 18 lower end mandril of ready-packaged joint 17
At 12 high point 121 of idler wheel, stopper rod 5 and piston 4 are located at lower dead center, and release spring 7 is in impaction state.In decentralization process, on
Release piece 16 receives in lower contact 14, has no effect on decentralization, and after this boost motor passes through injection well downhole flow regulator, upper release piece 16 is no longer met
Resistance can be opened to counterclockwise maximum position under the effect of the elastic force of torsional spring, at this point, lockwheel 12 is failure to actuate, then above propose this boosting
In device to injection well downhole flow regulator seating nipple, during upper mention, upper release piece 16 is hampered upwards, and release piece 16 is forced to turn downwards counterclockwise
Dynamic, pushing rolling wheels 12 follow it to rotate counterclockwise, until receiving in upper release piece 16 to lower contact 14.At this point, fast-assembling
The mandril 17 of connector 18 is left the high point 121 on idler wheel 12 and reaches buffer point 122, the displacement run down due to ready-packaged joint 18
Smaller, raised step also plays the role of radial support to steel ball 9.It is rotated up counterclockwise with release piece 13 at present, above proposes process
In, lower release piece 13 receives in lower contact 14, does not influence this boost motor and above mentions.
This boost motor above being mentioned apart from injection well downhole flow regulator appropriate location (being less than routine 7m), lower 13 outside of release piece is no longer hampered,
Maximum position can be opened up into, then transfers this boost motor and blanking plug is delivered to the inclined hole of injection well downhole flow regulator, lower release piece 13 at this time
It is obstructed downwards, forces it to have to rotate counterclockwise interior receipts, pushing rolling wheels 12 follow it to rotate counterclockwise, ready-packaged joint 18
On mandril 17 leave the buffer point 122 on idler wheel 12 and reach low spot 123, ready-packaged joint 18 moves down, and makes raised step not
Radial support is generated to steel ball 9 again, steel ball 9 is rolled into the expanding structure above raised step, and cannot pass through on lock tube 10
Through-hole is against on the undergauge step of stopper rod 5, and 5 lower end of stopper rod will will live without constraint under the effect of the elastic force of release spring 7
Plug 4 and stopper rod 5 upspring together, and liquid in the main cylinder 3 of 4 or more piston is passed through the Accelerating Removal obliquely of drainage hole 2.According to
Newton's third law, injection liquid generates equal in magnitude, contrary thrust to this boost motor, to help under this boost motor
Row drives blanking plug downlink.Field observation this boost motor speed increment is greater than 0.3m/s, and application effect is good.
The utility model has the advantages of simple structure, easy to maintenance, and manufacturing cost is low, therefore economic benefit is fabulous.
The utility model helps instrument downlink using recoil strength, has preferable acceleration effect, avoid it is previous merely according to
By aggravating bring operating difficulties, security risk is effectively eliminated, test pulling efficiency is improved.
Although the utility model is using new principle, new construction, there is no the previous test pulling techniques of change, and are not necessarily to
Other structures make any change, and scene is adaptable, convenient for promoting the use of.Although the utility model is using new principle, new knot
Structure, but there is no the previous test pulling techniques of change, and make any change without other structures, scene is adaptable, just
In popularization and use.
