Description
Technical field
The invention belongs to oil/gas drilling completion technique fields, and in particular to a kind of universal axle assembly and the application universal shaft are total
At high-frequency percussion helicoid hydraulic motor.
Background technique
Helicoid hydraulic motor is one kind using drilling fluid as power, liquid pressure energy is switched to the positive displacement well dynamic of mechanical energy
Drilling tool is petroleum, the drilling tool being most widely used in gas drilling field both at home and abroad at present, mainly includes that by-passing valve is total
At, motor assembly, universal axle assembly and driving-shaft assembly, by-pass valve assembly, motor assembly, universal axle assembly and driving-shaft assembly
It is sequentially connected from top to bottom, drilling fluid enters motor from by-passing valve, and certain pressure difference is formed in the import and export of motor, pushes
Rotor in motor assembly is rotated around the axis of stator, and it is total that revolving speed and torque by universal axle assembly passed to transmission shaft
At, then there is driving-shaft assembly to pass to drill bit, to realize drillng operation.
It is wanted to meet the drilling well failure on stratum etc. of soft or hard staggeredly bottom, hardcore etc. drillabilitys difference in the bottom of deep
It asks, occurs a variety of high-frequency percussion helicoid hydraulic motors in the prior art, the basic principle is that the drilling technology that spins, i.e., it will impact and rotation
Turn the drilling method combined, drill bit summarizes in the process of percussion drilling can be combined with rotary motion, it is easier to drilling well, tool
For body, rotating drilling technology passes through matching for the impactor generally by an impactor is installed on drill bit come what is realized
It closes, high frequency, uniform and stable impact energy can be formed in drilling process, drill bit and shaft bottom is enable to remain continuous
High frequency cutting, improves shear efficiency, the probing on the stratum suitable for drillabilitys differences such as complex formation probings.
But the high-frequency percussion helicoid hydraulic motor is because be to be realized by installing the modes such as impactor on drill bit, for example, existing
In technology, Patent No. 201310254618.6 discloses entitled cam-type high-frequency percussion spudder in this part Chinese patent
The device of tool, cam-type high-frequency percussion drilling tool connecting screw drilling tool in upper end in drillng operation, lower end connect drill bit, bore
Pressure passes to flag nut by the transmission shaft of helicoid hydraulic motor, the disc spring of tool, then passes to drill bit by flag nut.Using this
The workflow of the high-frequency percussion helicoid hydraulic motor of tool is that drilling fluid enters motor from by-passing valve, is formed in the import and export of motor
Certain pressure difference pushes the rotor in motor assembly to rotate around the axis of stator, and revolving speed and torque is total by universal shaft
At passing to driving-shaft assembly, then there is driving-shaft assembly to pass to the disc spring of tool, flag nut, then passed to by flag nut
Drill bit, to realize drillng operation.
The universal axle assembly of high-frequency percussion helicoid hydraulic motor, which plays, smoothly finally transmits the torque and revolving speed that motor generates
To the function of drill bit, and most commonly used in the prior art is Petal type cardan axle, and arc-shaped gear has the difficulty in processing, and
Flower works in the drilling fluids such as mud, as the raising valve tooth of drilling parameter can be worn faster, also, is easy to appear fatigue fracture
Or the valve tooth meshed together situations such as falling off；Also, since the drill bit of high-frequency percussion helicoid hydraulic motor connection can frequency
Higher stratum of spinning can feed back to the biggish shake of high-frequency percussion helicoid hydraulic motor above drill bit during its probing
Power degree, thus the damping with higher of universal axle assembly or shock-absorbing requirement for being connected to motor assembly, avoid by compared with
Big vibration dynamics is passed on motor assembly, is affected the offer power function of motor assembly, is reduced high-frequency percussion screw rod
The service life of drilling tool, it is serious even more so that high-frequency percussion helicoid hydraulic motor can not work.
