With conical seal (contact) face 71, so that the ball sealer 3 of input seals the through hole 70 from upper end under high pressure effect；External pressure
When value is more than the shear force of the shear pin 5, the ball seat 7 is fallen to be caught by ball seat catcher, and the connected ball is due to losing
Remove ball seat limitation ot it and fall, fall in ball seat upper end, the upper body component can depart from from the upper end of the outer tube.
Wherein, the ball positioning hole of the taper includes the upper body positioning hole of the cone-shaped formed on the barrel of the upper body
The lower body positioning hole 42 of cone-shaped on 22 barrel with forming the lower body, after the upper body is assemblied in the lower body, institute
Upper body positioning hole is stated to overlap in the hole heart with lower body positioning hole and form the taper and determine positioning hole.The connected ball is multiple, cone
The ball positioning hole of shape is multiple, arranged for interval, and the connected ball is positioned respectively to be placed in the ball positioning hole of the cone-shaped.It is preferred that
, the connected ball is six.
The shear pin is two or more, is evenly arranged in the pin hole radially set.
Wherein, it is machined with the barrel of the upper body on upper body pin hole 23, the barrel of the lower body and is machined with lower body pin
Nail 43, the lower body pin hole overlapped with the central axis of upper body pin hole and the lower body pin hole diameter be more than it is described
Pin locating slot 72 is machined with the diameter of upper body pin hole, the periphery of the ball seat；The shear pin 5 is through under described
Body pin hole, and in the upper body pin hole, and insert in the pin locating slot, the ball seat is fixed with realizing
Sealed structure is formed in the upper body sealing surface of the upper body, and with upper body sealing surface.
The shear pin is to be threadedly coupled with the upper body pin hole 23.
Wherein, the body of the ball seat catcher 8 is to be machined with the open cylinder in a upper end, the barrel of the cylinder
Catcher circulates relief hole 81, and the operating pressure pressure release above ball seat, the bottom of the cylinder are made after being fallen for ball seat
Provided with the bottom plate with sieve aperture 80, the ball seat fallen to catch and connected ball.
Further, be machined with lower body circulation relief hole 41 on the barrel of the lower body 4, the lower body circulation relief hole with
Catcher circulation relief hole is communicated by lower body component with the cavity that upper body inter-module is formed.When the ball seat is caught by the ball seat
Catch after device catches and connect with the bottom of ball seat catcher, the catcher circulation relief hole and lower body circulation relief hole expose, can
To realize quick pressure release.
Further, the external diameter in the exposed portion that the upper body is exposed to outside the outer tube is formed by conical surface transition undergauge
Reducing diameter part 21, the internal thread of the reducing diameter part is connected with the external screw thread of the ball seat catcher, the ball seat catcher and undergauge
The external diameter in portion is identical and internal diameter of respectively less than described sealing drum, so that in lower body component and the sky of upper body inter-module formation non-tight
Cavity configuration 15, so that the lower body circulation relief hole is connected with catcher circulation relief hole.
Wherein, it is formed with outer sleeve circular step face 44, the outer wall of the upper body and is formed on the inwall of the outer tube
There is upper body circular step face 24, the covering part 40 that the lower body is covered by the outer sleeve is located at the outer sleeve circular step
Between face and upper body circular step face, sealed between covering part 40 and the upper body, outer tube by O-ring seals formation, bag
Upper track sealing ring 12 and lower road sealing ring 13 are included, and the upper end of covering part 40 forms gap between the outer sleeve and upper body
11。
Wherein, during the upper body sealing surface is rounded face, the endoporus for being formed at the upper body, its upper end is formed with annular limit
Position step (not shown), to limit axially upwardly moving for the ball seat.
Wherein, the ball seat passes through twice O-ring seals 14 up and down and upper body sealing surface formation double containment.
Wherein, the internal upper part of upper body 2 is machined with the internal thread 20 for connecting drilling tool, forms the inwall in cone-shaped interface
On, the lower contact 10 is connection wye, and its external process is used for the external screw thread 101 for connecting Back-off Pipe String, and formation connects what is asked under
On the outer wall of cone-shaped connecting portion.
In oil gas well operations, the upper end of upper body is connected into drilling tool, lower body joint connection Back-off Pipe String, under it is predetermined to underground
Behind position, ball sealer is put into drilling rod, turn on pump falls into the sealing of ball seat under the effect of the pressure to drill string pump high pressure, ball sealer
The conical surface, because sealing ring and the formation of upper body sealing surface of ball seat are sealed, pressure continues to rise, when pressure exceedes cutting for shear pin
Value is cut, ball seat is fallen into ball seat catcher, pressure discharges from the circulation relief hole of ball seat catcher, and ball seat falls into ball seat catcher
Afterwards, connected ball loses support and spacing, falls into ball seat catcher, above puts on body, upper body component and lower body component, outer sleeve point
Open, realization is slipped out of the hand.
Beneficial effects of the present invention are as follows：
1) function of pushing forward or reverse is realized：It is fashionable under Back-off Pipe String, due to can guide type hydraulic releasing tool
Upper body component be connected with lower body component using connected ball, and using ball seat limitation steel ball movement, realize and push rotating forward or anti-
Turn.
2) realize and safely and fast slip out of the hand：Throw after ball sealer is suppressed by suppressing, ball seat pin sheared, ball seat is moved down,
Connected ball is released simultaneously, above puts on body, upper body component is separated with lower body component, outer sleeve, you can realization is rapidly separated.
3) it is directed to steel wire operation：Can guide type hydraulic releasing tool maximum outside diameter and shell clearance it is smaller, in lower contact
Major diameter variable buckle is installed in bottom, solves the problem of steel wire operation is carried out in the case of non-tieback.
4) can quick tieback：To meet co-well oil-pumping and water-injecting needs, can guide type hydraulic releasing tool bottom carry sealing drum,
Quick tieback can be realized.
5) it is directed to fishing：
(1) increase tool bore, can the bottom of guide type hydraulic releasing tool leave certain space, can catch
The cable guard fallen, and fishing is not influenceed；
(2) upper tool part leaves fishing head, and fishing spear can be used to carry out fast salvaging operation；
(3) lower sides of lower body have circulation relief hole, if can not easily propose instrument during salvaging, can be carried out after catching
Huge discharge circulates pressure release.
Described above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
