Amount component communicates and can automatically control the pressure of the drill；The pressure of the drill automatically controls pipe nipple upper end connection underground rotary power unit, underground rotation
Driving torque driving bottom tubing string rotary drilling can be produced by rotating power apparatus, and underground rotary power unit needs can when orienting
Receive the control instruction of measurement while drilling component and stop torque output；Underground rotary power unit upper end connects tubing string propeller,
Tubing string propeller can be promoted 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 the pressure of the drill and can automatically adjust and push away
The power and moving displacement size entered；The emergent safe pipe nipple of tubing string propeller upper end connection, safe pipe nipple of meeting an urgent need can realize top
Disengaging and reconnection of the tubing string with bottom tubing string, safe pipe nipple upper end connection coiled tubing of meeting an urgent need；It is connected with this tubular column structure
Several spinning multifunction cartridges, spinning multifunction cartridge are made up of rolling righting mechanism and rotary sleeve, rotary sleeve
Fluid power or driven by power rotation in tubing string can be relied on.
Tubing string propeller is by the compound step-by-step movement support arm of multiple spot or is in rolling contact mechanism and forms.
The beneficial effects of the invention are as follows：The present invention realize make coiled tubing drilling high rigidity tubing portion have it is compound
Drilling ability and the pressure of the drill from traction drive ability, accurately control drill bit acquisition stabilization, reduce coiled tubing helical buckling effect
Deposited with horizontal segment landwaste, drag reduction drop is rubbed, and the horizontal-extending ability of coiled tubing drilling is greatly enhanced.
Brief description of the drawings：
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention.
