Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figures 1 to 6, a kind of hydroscillator, comprising: vibration pipe nipple and the power sub being connect with vibration pipe nipple.
Vibration pipe nipple includes: slide-bar 1, sliding sleeve 2, vibrating spring 3, piston terminal 4 and vibration shell 5.Slide-bar 1 has along it
I 1-1 of runner made of axially extending, 1 upper end of slide-bar are connect with drilling rod, and slide-bar 1 and sliding sleeve 2 are made up of spline along its axial direction
It is slidably connected.Sliding sleeve 2 is connect with vibration shell 5.The lower end of slide-bar 1 is installed by piston terminal 4, the lower end of piston terminal 4 and sliding sleeve 2
Between connection vibrating spring 3 formed elastic connection.Piston terminal 4 have along its it is axially extending made of II 4-1 of runner.Runner I
1-1 is connected to II 4-1 of runner.
Power sub includes: connector sleeve 6, mandrel 7, roll-shell 8, turbo blade 9, determines valve 10 and eccentric dynamic valve 11.Even
The lower end of female connector 6 constitutes with the upper end of roll-shell 8 and connect around its axial one-directional rotation.Mandrel 7 has from the upper end edge
III 7-1 of runner made of axis extends downwardly, from its lower end edge axis upwardly extend made of IV 7-2 of runner, through its side wall
I 7-3 of through-hole being connected to III 7-1 of runner and II 7-4 of through-hole being connected to through its side wall with IV 7-2 of runner.The upper end of mandrel 7 with
The connection of connector sleeve 6, its lower end are set in roll-shell 8.In roll-shell 8 between II 7-4 of I 7-3 of through-hole and through-hole
Successively mounting turbine blades 9 and the bias with I 11-1 of valve opening move valve 11 from top to bottom on wall.Installation has valve opening on mandrel 7
II 10-1's determines valve 10.
When acting on turbo blade 9 by the drilling fluid that drilling pump exports, driving turbo blade 9 makes it drive roll-shell 8
It is rotated relative to mandrel 7, generates the first motor pattern at this time, i.e., around the rotation of axis.At the same time, eccentric dynamic valve 11 is relatively fixed
Valve 10, which rotates so that II 10-1 of valve opening is connected to I 11-1 generating period of valve opening, changes area of passage generating period.
Thus the pressure also generating period variation for causing the drilling fluid that 4 lower end of piston terminal is subject to, as I 11-1 of valve opening and valve opening II
When 10-1 is closed, the pressure that piston terminal 4 is subject to reaches maximum value, drives sliding sleeve 2 to rise with respect to slide-bar 1 at this time；When valve opening I
When 11-1 is connected to II 10-1 of valve opening, the pressure that piston terminal 4 is subject to becomes smaller, and sliding sleeve 2 is just under the thrust of vibrating spring 3 at this time
Opposite slide-bar 1 declines, and under this cyclically-varying, generates second of motor pattern, i.e., along axial simple harmonic oscillation.Due to inclined
When the dynamic valve 11 of bias rotates eccentric vibrating can occur for the mass center and center of rotation of valve 11 aroused in interest not in same place.At this time
Generate the third motor pattern, i.e., swing radially.Three kinds of motor patterns are overlapped mutually to form complex vibration, to substantially drop
Friction in low drilling process.
Due to being one-directional rotation connection between connector sleeve 6 and roll-shell 8, when the upper and lower ends of the hydroscillator are equal
It being connect with drilling rod in use, one-directionally rotating connection due to using, drilling rod also will drive hydroscillator rotation when rotating, but
Due to drilling fluid can also drive turbo blade 9 rotate, can accelerate hydroscillator lower end connect drilling rod revolving speed to
Improve rate of penetration.Therefore the hydroscillator is especially suitable for being arranged close to the position of drill bit to improve drilling efficiency.
Due to not only making area of passage cyclically-varying when the dynamic valve 11 of bias rotates, but also generate eccentric swing.Therefore
Axial dimension is greatly reduced, is avoided and is generated biggish Bending Deformation because axial dimension is longer and accelerate metal fatigue.Together
When since the quality of eccentric dynamic valve 11 is smaller and revolving speed is larger, the hunting frequency generated is bigger, amplitude is smaller, not only improves
The vibrating effect of complex vibration, and extend the service life of associated components.
Preferably, it is equipped with dynamic sealing between sliding sleeve 2 and slide-bar 1, vibrates and is equipped between shell 5 and piston terminal 4
Dynamic sealing.Doing so can prevent drilling fluid from revealing, and avoid the pressure for being therefore subject to piston terminal 4 from becoming smaller and vibration is caused to subtract
It is weak, influence vibrating effect the case where occur.
Preferably, the top of roll-shell 8 has I 8-1 of boss, and positioning terminal 16 is installed in the lower end of connector sleeve 6,
Positioning terminal 16 has II 16-1 of boss, and thrust ball bearing I 14 is equipped between II 16-1 of I 8-1 of boss and boss to make to rotate
Shell 8 can be rotated relative to connector sleeve 6 and mandrel 7.The bonding strength that can enhance rotation connection is done so, avoids occurring disconnected
It splits.
Preferably, I 11-1 of valve opening and II 10-1 of valve opening is long arc-shaped holes.On the one hand portion can be reduced by doing so
On the other hand the use of part material can make Mass Distribution more uneven to improve swing effect.
Preferably, power sub further includes connector 12, and connector 12 is mounted on the lower end of roll-shell 8, even
Connector 12 have along its it is axially extending made of runner V, runner V is connected to IV 7-2 of runner.It does so convenient for connecting other works
Make device, while being expelled directly out convenient for drilling fluid.
Preferably, in connector 12 installed thrust ball bearing II 15 to enabling roll-shell 8 and connector 12
It is enough to be rotated relative to mandrel 7.The bonding strength that can enhance rotation connection is done so, and is reduced between two components relatively rotated
Frictional force.
Preferably, the check valve for allowing water flow one-way flow is provided between the lower end of slide-bar 1 and piston terminal 4
13.Drilling fluid adverse current can be prevented by doing so, and act on the pressure of drilling fluid all on piston terminal 4, guarantee vibrating effect.
Preferably, the quantity for determining valve 10 and eccentric dynamic valve 11 is several, and along the axial equidistant of mandrel 7
Setting.It does so convenient for improving oscillatory forces, generates and preferably swing effect.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
