It receives the control instruction of measurement while drilling component and stops torque output；Underground rotary power unit upper end connects tubing string propeller,
Tubing string propeller can be pushed frontal rigid tubing string and draw coiled tubing using the borehole wall or casing wall as fulcrum to be made at coiled tubing
In tension state, tubing string propeller can automatically control pipe nipple communication with measurement while drilling component and bit pressure and can automatically adjust and push away
Into power and moving displacement size；The safe pipe nipple of tubing string propeller upper end connection emergency, safe pipe nipple of meeting an urgent need can be realized top
The disengaging and reconnection of tubing string and lower part tubing string, safe pipe nipple upper end connection coiled tubing of meeting an urgent need；It is connected on this tubular column structure
Several spinning multifunction cartridges, spinning multifunction cartridge are made of rolling righting mechanism and rotary sleeve, rotary sleeve
By fluid power in tubing string or rotation can be driven by electricity.
Tubing string propeller is by the compound step-by-step movement support arm of multiple spot or is in rolling contact mechanism and forms.
Make the high rigidity tubing portion of coiled tubing drilling with compound the beneficial effects of the present invention are: the present invention realizes
Drilling ability and from traction drive ability, the accurate drill bit that controls obtains stable bit pressure, reduces coiled tubing helical buckling effect
It is deposited with horizontal segment landwaste, drag reduction drop is rubbed, and the horizontal extension ability of coiled tubing drilling is greatly enhanced.
Detailed description of the invention:
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural diagram of the present invention.
Specific embodiment:
