Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As shown in Figures 1 to 6, a kind of hydroscillator, including：Vibration pipe nipple and the power sub being connected with vibration pipe nipple.
Vibration pipe nipple includes：Slide-bar 1, sliding sleeve 2, vibrating spring 3, piston terminal 4 and vibration housing 5.Slide-bar 1 has along it
The axially extending 1-1 of runner I, the upper end of slide-bar 1 is connected with drilling rod, and slide-bar 1 is made up of along its axial direction with sliding sleeve 2 spline
It is slidably connected.Sliding sleeve 2 is connected with vibration housing 5.The lower end of slide-bar 1 is installed by the lower end of piston terminal 4, piston terminal 4 and sliding sleeve 2
Between connect vibrating spring 3 formed elastic connection.Piston terminal 4 has along its axially extending 4-1 of runner II.Runner I
1-1 is connected with the 4-1 of runner II.
Power sub includes：Adapter sleeve 6, mandrel 7, roll-shell 8, turbo blade 9, determine 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 is connected around its axial one-directional rotation.Mandrel 7 with from its upper end edge
The 7-1 of runner III that axis is extended downwardly, the 7-2 of runner IV upwardly extended from its lower end edge axis, through its side wall
The 7-3 of through hole I connected with the 7-1 of the runner III and 7-4 of through hole II connected with the 7-2 of runner IV through its side wall.The upper end of mandrel 7 with
Adapter sleeve 6 is connected, its lower end is arranged in roll-shell 8.In roll-shell 8 between the 7-3 of through hole I and the 7-4 of through hole II
Mounting turbine blades 9 and the bias with the 11-1 of valve opening I move valve 11 successively from top to bottom on wall.Being installed on mandrel 7 has valve opening
II 10-1's determines valve 10.
When the drilling fluid exported by drilling pump acts on turbo blade 9, turbo blade 9 is driven it is driven roll-shell 8
Rotated relative to mandrel 7, now produce the first motor pattern, i.e., around the rotation of axis.At the same time, eccentric dynamic valve 11 is relatively fixed
Valve 10 is rotated and the 10-1 of valve opening II is connected with the 11-1 generating periods of valve opening I so that area of passage generating period changes.
Thus also generating period changes the pressure of the drilling fluid that the lower end of initiation piston terminal 4 is subject to, when the 11-1 of valve opening I and valve opening II
When 10-1 is closed, the pressure that piston terminal 4 is subject to reaches maximum, now drives sliding sleeve 2 to rise with respect to slide-bar 1；When valve opening I
When 11-1 is connected with the 10-1 of valve opening II, the pressure that piston terminal 4 is subject to diminishes, and now sliding sleeve 2 is just under the thrust of vibrating spring 3
Decline with respect to slide-bar 1, under this cyclically-varying, produce second motor pattern, i.e., simple harmonic oscillation vertically.Due to inclined
The barycenter and center of rotation of valve aroused in interest 11 can occur eccentric vibrating not in same place when the dynamic valve 11 of bias is rotated.Now
Produce the third motor pattern, i.e., swing radially.Three kinds of motions pattern is overlapped mutually to form complex vibration, so as to significantly drop
Friction in low drilling process.
Due to being one-directional rotation connection between adapter sleeve 6 and roll-shell 8, when the upper and lower ends of the hydroscillator are equal
It is connected with drilling rod when using, due to can also drive hydroscillator to rotate when being rotated using one-directional rotation connection, therefore drilling rod, but
Can also drive turbo blade 9 to rotate due to drilling fluid, thus can accelerate hydroscillator lower end connect drilling rod rotating speed so as to
Improve rate of penetration.Therefore the hydroscillator is especially suitable for being arranged close to the position of drill bit so as to improve drilling efficiency.
Not only make area of passage cyclically-varying when being rotated due to the dynamic valve 11 of bias, and produce eccentric swing.Therefore
Greatly reduce axial dimension, it is to avoid to produce because axial dimension is more long larger Bending Deformation to accelerate metal fatigue.Together
When because the quality of the dynamic valve 11 of bias is smaller and rotating speed is larger, therefore the hunting frequency for producing bigger, amplitude is smaller, not only improves
The vibrating effect of complex vibration, and extend the service life of associated components.
Preferably, dynamic sealing is provided between sliding sleeve 2 and slide-bar 1, is provided between vibration housing 5 and piston terminal 4
Dynamic sealing.Do so is prevented from drilling fluid leakage, it is to avoid therefore the pressure that piston terminal 4 is subject to is diminished and is caused vibration to subtract
Weak, influence vibrating effect situation occurs.
Preferably, positioning terminal 16 is installed in the lower end that the top of roll-shell 8 has the 8-1 of boss I, adapter sleeve 6,
Positioning terminal 16 have be provided with thrust ball bearing I 14 between boss II 16-1, the 8-1 of boss I and the 16-1 of boss II so that rotate
Housing 8 can be rotated relative to adapter sleeve 6 and mandrel 7.Do so can strengthen the bonding strength for rotating connection, it is to avoid occur disconnected
Split.
Preferably, the 11-1 of valve opening I and the 10-1 of valve opening II are long arc-shaped holes.On the one hand do so can reduce portion
The use of part material, on the other hand can make Mass Distribution more uneven so as to improve swing effect.
Preferably, power sub also includes connector 12, and connector 12 is arranged on the lower end of roll-shell 8, even
Joint 12 has along its axially extending runner V, and runner V is connected with the 7-2 of runner IV.Do so is easy to connect other works
Make device, while being easy to drilling fluid to be expelled directly out.
Preferably, in connector 12 installed thrust ball bearing II 15 so that roll-shell 8 and the energy of connector 12
It is enough to be rotated relative to mandrel 7.Do so can strengthen between the bonding strength for rotating connection, and two parts of reduction relative rotation
Frictional force.
Preferably, being provided between the lower end of slide-bar 1 and piston terminal 4 allows the check valve of current one-way flow
13.Do so is prevented from drilling fluid countercurrently, the pressure of drilling fluid is all acted on piston terminal 4, it is ensured that vibrating effect.
Preferably, the quantity for determining valve 10 and eccentric dynamic valve 11 is several, and along the axially equidistant of mandrel 7
Set.Do so is easy to improve oscillatory forces, produces and preferably swings effect.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of the technology of the present invention principle is not departed from, some improvement and deformation can also be made, these improve and deform
Also should be regarded as protection scope of the present invention.
