It drives working pipe string to carry out rountrip in well in a manner of spinning movement by matching with slips etc., and underground is cooperated to bore
Tool is together to complete milling, bore the construction operations such as plug, sidetracking, well-flushing and unfreezing.During workover treatment, due to the feelings of deep-well
Condition down tube string twisting strain amount is larger, it usually needs turntable provides certain revolving speed to support and close；And the power of shaft bottom operation mainly according to
It is only used for playing mate-assist under the specific conditions such as bit freezing by mud motor, turntable, with certain torque and turn
Speed emergency.As snubbing serving equipment construction scope is gradually to overhaul field Directional Extension, to the synthesis of hydraulic swivel head
Performance requirement steps up.In the case where pipe string is without mud motor, turntable applies power and plays a leading role, and is carrying out
When the underground constructions techniques such as sidetracking, set mill, scraping, by promoting operating speed, the generation of the accidents such as bit bouncing, bit freezing can be reduced；?
The case where encountering bit freezing needs to control turntable unfreezing, turntable is needed to provide higher rotation speed during unfreezing.Due to snubbing serving
Equipment is limited by structure type itself and the factors such as space layout restrict, and turntable is when that can provide highest torque 30000NM
Working speed only up to reach 60RPM or so, be unable to satisfy without the performance exported under power drilling tool to turntable high speed rotation
It is required that.
Summary of the invention
The present invention is directed to conventional snubbing serving hydraulic swivel head control system, provides a kind of novel snubbing serving equipment
With turntable multilevel control system, may be implemented to solve normal the Multistage Control of turntable output revolving speed and torque under firm power
Advise no killing well equipment operation when hydraulic swivel head revolving speed it is relatively low, be unable to satisfy without down-hole equipment and unfreezing etc. in special circumstances to turn
The performance requirement of the high revolving speed output of disk.
The present invention is to be attained in that by following technical solution
A kind of snubbing serving sets false rotary multilevel control system, includes oil inlet A, oil return B, motor, it is characterised in that: motor
Quantity be it is multiple；It is 1 that water brake brake is connected on each motor respectively for controlling the operating of motor, motor number
When, the actuator port of motor is directly connect with oil inlet A, oil return B, for driving turntable to rotate；When motor number is greater than 1,
In the actuator port of a motor directly connect with oil inlet A, oil return B, a reversal valve is at least connected on motor in addition, and lead to
It crosses reversal valve to connect with oil inlet A, oil return B, connects and be also connected with flushing valve on the motor of reversal valve, flushing valve connects oil inlet A, oil return
B, flushing valve are that motor rinses cooling, and reversal valve is for controlling rotary speed gear.
The quantity of motor is 1-4.
A ball valve is connected on each water brake brake, ball valve can be closed individually for carrying out to its corresponding brake
Maintenance.
Optimal motor number is 4, and when motor number is four, one actuator port of motor is connect with oil inlet A, oil return B；
The working hole P of flushing valve respectively with two drain tap L2 of motor, three drain tap L3 of motor, four drain tap L4 of motor；On each motor
It is connected with water brake brake respectively for controlling the operating of motor, between motor two, motor three, motor four and flushing valve at least
It is connected with a reversal valve.
The present invention has the advantages that compared with prior art:
1, the motor system and reversal valve of the invention by adding multiple groups parallel connection passes through the motor and commutation valve group of different number
Close, it can be achieved that when no killing well equipment operation rotary speed the switching of height difference；By to the more of turntable control system speed
Grade control mode may be implemented snubbing serving equipment and carry out the different construction operation processes such as brill plug, milling, unfreezing to turntable
The different of revolving speed are exported to require；
2, the present invention is effectively reduced case temperature, effectively extends control by flushing valve to the flushing action of servo motor shell
The service life of all parts and hydraulic oil in system processed；Extend the Acceptable life of motor.
Detailed description of the invention:
Fig. 1 is the control principle drawing of the one of embodiment of the present invention.
Specific embodiment:
