Hit inside device, then the fluid passage of Jing turbochargings assembly, the inner chamber of the first sleeve 1.3, ring cavity 1.6.4, second sleeve 1.7
Inner chamber, the first waist-shaped hole 1.8.4, the second waist-shaped hole 1.9.3 flow out bumper jar.Flow into the high pressure well liquid inside drilling rod and drive whirlpool
Wheel rotor rotation, forms the concentric rotational movement around turbine central axis, so as to the kinetic energy of cleaner for high-pressure drilling fluid be converted at a high speed
The mechanical energy of rotation, and pressure balancing system is delivered to by pressure side or valve disc 1.8 by turbine spindle 1.2.1.Due to valve disc 1.8
With two effect partials that pressure balancing system is same part by pressure side, so turbine spindle 1.2.1 will drive valve disc 1.8
One superhigh speed rotates.Because valve seat 1.9 is fixed, when valve disc 1.8 rotates at a high speed, the first waist-shaped hole 1.8.4 of valve disc 1.8 and valve
The second waist-shaped hole 1.9.3 on seat 1.9 is overlapping, and makes drilling fluid in the rotation formed with valve seat 1.9 by valve disc 1.8
The circulation area generating period change of valve, so that the flow stream pressure generating period change of the upstream of valve disc 1.8, that is, generate
Pressure pulse.
When the area of passage between valve disc 1.8 and valve seat 1.9 becomes hour, the upstream pressure of rotary valve is raised.Work as flow-passing surface
When product is minimum, i.e., when the first waist-shaped hole 1.8.4 of valve disc 1.8 is not overlap with the second waist-shaped hole 1.9.3 on valve seat 1.9,
The upstream high flow stream pressure of rotary valve reaches maximum.Greatly flow stream pressure is acted on piston 3.6 and connecting shaft 3.3,
Compress disc spring group 3.8 and the high pressure kinetic energy of drilling fluid be changed into into disc spring potential energy to be stored.The compression campaign of disc spring group 3.8
Drill bit is transmitted motion to by the housing of the bumper jar of the present invention, bottomhole is moved downward.
When the area of passage change between valve disc 1.8 and valve seat 1.9 is big, the reduced pressure of the transition joint side of rotary valve.
When area of passage is maximum, i.e., when the first waist-shaped hole 1.8.4 of valve disc 1.8 is complete with the second waist-shaped hole 1.9.3 on valve seat 1.9
During overlap, the upstream high flow stream pressure of rotary valve reaches minimum.Because the pressure of the drill is more than flow stream pressure minimum, so front place
Release energy in the disc spring group 3.8 of compressive state, disc spring group 3.8 extends and transmits motion to brill by the housing of bumper jar
Head, makes drill bit move upwards.
Because turbine can provide stable rotary motion under cleaner for high-pressure drilling fluid effect so that rotary valve has certain week
Phase, under periodic pressure impulse action, the periodicity that a kind of near drill bit three-dimensional bumper jar of the present invention is generated vertically is high
Frequency wriggle, make the friction condition between drill string and the borehole wall change, drill string elasticity send brill the instantaneous coefficient of sliding friction increasing
Long speed is reduced, so as to reducing frictional resistance, improving rate of penetration.Meanwhile, by the way that cleaner for high-pressure drilling fluid is introduced in pressure balancing system
Chamber, flow stream pressure is acted on bottom end face of the pressure balance by pressure side or the valve disc dome platform 1.8.2 of valve disc 1.8, while boring
Well liquid is entered in the second cavity 1.12, forms low pressure liquid.Highly pressurised liquid forms pressure reduction with the interaction of low pressure liquid, reduces
The load of bearing, so as to extending the working life of bearing.And the service life of bottomhole depends primarily on what is used
The operating time of bearing, thus pressure balancing system extends the service life of the bumper jar of the present invention.
Wherein, a kind of near drill bit of the invention three-dimensional bumper jar, is typically mounted near drill bit, in high pressure when actually used
Itself produce axial high frequency under the driving effect of drilling fluid to wriggle, and because the invention has used a kind of the asymmetric of Concentric rotation
Formula valve arrangement, can make itself axial high frequency that the radial vibration of high frequency is produced while wriggling.Its axial high frequency wriggle by drill string with
Static friction state change between the borehole wall is sliding friction state.Meanwhile, its radial direction dither cycle reduces drill string
Normal pressure between the borehole wall.The common impact of both effects makes the growth of the frictional resistance between bottom hole assemblies and the borehole wall
Speed is significantly reduced, and can significantly reduce frictional resistance, prevents to drag pressure phenomenon, improves the effect of load transfer, improves machine
Tool drilling speed, saving drilling cost.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
