Description
Technical field
A kind of anti-rotation the present invention relates to oil and gas industry drilling engineering is sent into instrument.
Background technology
In oil and gas industry, drilling engineering is that key technology big, that risk is high is invested in oil-gas reservoir recovery process,
The accident rate occurred in drilling engineering is also at a relatively high.It occur frequently that stick-slip phenomenon, stick-slip phenomenon are due in drilling process
Drill string twists under certain moment of torsion, and the torsion that drill string produces when moment of torsion reaches a certain critical value can discharge suddenly.Drilling tool
Stick-slip phenomenon usually come at underground vibrations, be particularly easy to trigger diamond bit to collapse tooth, shorten bit life, it is also possible to lead
Cause logger failure.In addition, need to carry out deflecting the boring when horizontal well drilling and extended reach well, and deflecting the boring needs
Drilling engineer holds tool-face, and during actual well drilled, since the reaction torque of mud motor acts on, frequently result in
Tool-face constantly deflects, can not accurate deflecting.In addition in extended reach well and horizontal well, due to rubbing for horizontal segment drill string and wellbore
It is big to wipe resistance, drill string is sent into difficulty, usually makes drill bit be difficult to obtain effective the pressure of the drill, seriously constrains drilling efficiency.
For the technical barrier of above-mentioned drilling engineering, it have developed part drilling tool both at home and abroad and overcome to a certain extent

Connection, lower contact lower end and anti-lost housing screwed connection.
The beneficial effects of the invention are as follows：(1) present invention blocks the borehole wall using slips, and the moment of torsion for putting on drill string is passed to
The borehole wall, it is therefore prevented that the torsional deflection of drill string, can effectively overcome stick-slip phenomenon and tool-face sideslip problem；(2) present invention utilizes brill
Well liquid driving output shaft stretches out, and effectively drill bit can be applied and stablize the pressure of the drill, slips blocks the borehole wall, prevents drill string rollback from scratching
It is bent；(3) drill string control slips stretching retraction is put by above putting, operation is simple and reliable；(4) can eliminate axial from bit part
Vibrations.
