Description
Technical field:
The present invention relates to a kind of pipe continuously and be drilled well technical field, particularly to the one continuous pipe anti-moment of torsion of drilling well
Device.
Background technology:
In the continuous pipe drillng operation of present stage, owing to managing the most revolvable particularity, the pressure of the drill, torsion continuously
Square and DHA are restricted, when stratum hinders moment of torsion to be supplied to creeping into of drill bit more than helicoid hydraulic motor
During moment of torsion, easily cause rotor torque to accumulate, and react on stator and down-hole equipment, reaction torque can not and
Time release continuous pipe can be caused to damage, the problem such as helicoid hydraulic motor fault and load transfer difficulty, so can only be low
The pressure of the drill, high drilling speed creep into, and seriously constrain efficiency and the application of continuous pipe drilling well.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of anti-torquer of pipe drilling well continuously, and this device realizes
Avoid in continuous pipe drilling process because of stratum hinders moment of torsion excessive and the accumulation of helicoid hydraulic motor awl reaction torque and lead
The continuous pipe caused damages, helicoid hydraulic motor failure problems, it is possible to achieve big the pressure of the drill, high drilling speed during pipe drilling well continuously
Creep into, further shorten continuous pipe drilling period, reduce drilling cost.Overcome existing continuous pipe to creep into
During because of stratum hinder that moment of torsion is excessive and the accumulation of helicoid hydraulic motor awl reaction torque and the continuous pipe that causes damages,
Helicoid hydraulic motor failure problems, can only the deficiency crept into of low the pressure of the drill, high drilling speed.
The technical solution used in the present invention is: a kind of anti-torquer of pipe drilling well continuously, including top connection, company
Female connector and lower contact；Top connection lower end inner wall thread seal connects torque sleeve, and adapter sleeve is placed in top connection lower end
And it being sleeved on outside torque sleeve, adapter sleeve inwall step is articulated at the outer step of torque sleeve lower end, and torque sleeve leads to
Crossing self-locking block locking adapter sleeve, butterfly spring is placed in inside self-locking block, and stop collar thread seal is connected to moment of torsion
Inside set and block butterfly spring, adapter sleeve lower end thread seal connects lower contact.
The invention has the beneficial effects as follows: present invention, avoiding in continuous pipe drilling process because stratum hinders moment of torsion mistake
The continuous pipe that big and helicoid hydraulic motor awl reaction torque is accumulated and caused damages, helicoid hydraulic motor failure problems, permissible
When realizing continuous pipe drilling well, big the pressure of the drill, high drilling speed creep into, and further shorten continuous pipe drilling period, reduce
Drilling cost.
Accompanying drawing illustrates:
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention:
As it is shown in figure 1, a kind of anti-torquer of pipe drilling well continuously, including top connection 1, adapter sleeve 4 and under connect
6；Top connection 1 lower end inner wall thread seal connects torque sleeve 2, and adapter sleeve 4 is placed in top connection 1 lower end also
Being sleeved on outside torque sleeve 2, adapter sleeve 4 inwall step is articulated at the outer step of torque sleeve 2 lower end, moment of torsion
Set 2 locks adapter sleeve 4 by self-locking block 3, and butterfly spring 7 is placed in inside self-locking block 3, stop collar 5 screw thread
Being sealedly connected on inside torque sleeve 2 and block butterfly spring 7, adapter sleeve 4 lower end thread seal connects lower contact
6。
In continuous pipe drilling process, connect continuously pipe and the top connection 1 of the present invention, lower contact 6 with connector
Connect helicoid hydraulic motor.In drilling process, the obstruction moment of torsion provided when drilling strata is continuous more than normally creeping into
During the nominal torque that pipe can bear, adapter sleeve 4 skids off self-locking block 3 rotation of sliding, because adapter sleeve 4
There is no with top connection 1 and be connected, so the continuous pipe on top connection 1 and top thereof does not rotate, now this device
Protection pipe continuously, not by this part moment of torsion effect, reduces the damage of continuous pipe, extends continuous tube lifetime.It addition,
In the course of the work, the rotor of helicoid hydraulic motor also accumulation moment of torsion, when creeping into stopping, reaction torque can discharge
Come and act on screw drilling tool stator and continuous pipe, by this device, equally protection helicoid hydraulic motor and
Pipe is not destroyed by this part moment of torsion continuously, it is possible to carry out big the pressure of the drill, the continuous pipe drilling well of high drilling speed, shortens even
Continuous pipe drilling period, reduces continuous pipe drilling cost.
It is understood that above with respect to the specific descriptions of the present invention, be merely to illustrate the present invention and be not subject to
It is limited to the technical scheme described by the embodiment of the present invention, it will be understood by those within the art that, still
The present invention can be modified or equivalent, to reach identical technique effect；Need are used as long as meeting
Want, all within protection scope of the present invention.
