Automatic rigger 8 mainly comprises rotary motor, coaster, telescopic arm, binding clip, and under fluid motor-driven, automatic rigger 8 overall wraparound can turn central rotation, and binding clip is established in telescopic arm bottom, can hang hold drilling tool thribble when operation.

By automatic rigger 8, the cooperatively interacting of pillar tube drawbench 6, the Automatic Conveying of drilling tool thribble between quadruple board platform fingerboard 16 and well head can be realized.

Hoisting mechanism I5 bottom is provided with powerplant module, is made up of respectively paired motor, reduction box, gear; The top of hoisting mechanism I5 be provided with integrate shackle, mud uninterruptedly circulates, creep into the multi-function device of spinfunction; Be bolted between the upper and lower part of hoisting mechanism I5.During operation, hoisting mechanism I5 realizes moving up and down by the engagement of wheel and rack; Hook carries and passes to gear by hoisting mechanism I5, then passes to derrick 4 by the engagement of wheel and rack 7.

Hoisting mechanism II9 top is provided with powerplant module, is made up of respectively paired motor, reduction box, gear; Bottom suspention has conventional top to drive, and top is driven back-up tong and can be moved up and down; Reverse torque beam is provided with, for bearing the reaction torque of pushing up and driving when creeping between the upper and lower part of hoisting mechanism II9.During operation, hoisting mechanism II9 realizes moving up and down by the engagement of wheel and rack; Hook carries and passes to gear by hoisting mechanism II9, then passes to derrick 4 by the engagement of wheel and rack 7.

The circulation of drilling fluid in whole drilling process can be realized by the cooperation of hoisting mechanism I5, hoisting mechanism II9, mud line manifold 12 make a trip uninterruptedly, continuously and creep into.

Tube drawbench 15, dynamic catwalk 2, hoisting mechanism I5, pillar grab pipe machine 6, automatically rigger 8 and hoisting mechanism II9 all with electrohydraulic controlling mechanism 19 UNICOM, electrohydraulic controlling mechanism 19 is integrated in the Hydraulic Station 20 on ground.

Corresponding position sensor is provided with in the executing agency of above-mentioned tube drawbench 15, dynamic catwalk 2, hoisting mechanism I5, pillar grab pipe machine 6, automatically rigger 8 and hoisting mechanism II9, detect or spacing control for position, all position sensors are connected with electrohydraulic controlling mechanism 19 signal, and utilize the action of electrohydraulic controlling mechanism 19 to each execution unit in this covering device to carry out PLC technology, make control have safety interlock function, can also 3 pairs, control room all parts Long-distance Control be passed through.

Apparatus of the present invention creep into flow process, implement according to following steps:

Step 1. hoisting mechanism I5 and hoisting mechanism II9 is all in low level, single drill pipe 10 is rolled into dynamic catwalk 2 by operation pipe rack 15, meanwhile, hoisting mechanism I5 slurry channel is opened, hoisting mechanism II9 slurry channel is closed, hoisting mechanism II9 stops creeping into, completing the shackle action with drilling tool, hoisting mechanism I5 starts to creep into, and sees Fig. 4.

Single drill pipe 10 is sent to pillar grab pipe machine 6 place by step 2. dynamic catwalk 2; Meanwhile, hoisting mechanism II9 rises to certain altitude, and hoisting mechanism I5 continues to creep into, and sees Fig. 5.

Step 3. pillar grab pipe machine 6 captures single drill pipe 10, is become plumbness and be promoted to certain altitude to be submitted to hoisting mechanism II9, and top, hoisting mechanism II9 bottom is driven and completed upper button with single drill pipe 10; Meanwhile, hoisting mechanism I5 continues to creep into, and dynamic catwalk 2 times horizontal resets, are shown in Fig. 6.

Step 4. hoisting mechanism II9 takes single drill pipe 10 and is displaced downwardly to hoisting mechanism I5, hoisting mechanism II9 slurry channel is opened and is completed in the upper unit of hoisting mechanism I5 on single drill pipe 10 and the drilling tool crept into and pulls work, hoisting mechanism I5 closes slurry channel, stops creeping into, hoisting mechanism II9 starts drilling well, sees Fig. 7.

Step 5. in same track, hoisting mechanism I5 all the time under, hoisting mechanism II9 is all the time upper, and hoisting mechanism I5 unclamps drilling tool and goes upward to predetermined altitude, and simultaneously hoisting mechanism II9 continues drilling well, sees Fig. 8.

Step 6. hoisting mechanism II9 creeps into during close to hoisting mechanism I5 upper unit, hoisting mechanism II9 stops creeping into, completing the shackle action with drilling tool, hoisting mechanism I5 slurry channel is opened, hoisting mechanism II9 slurry channel is closed, and is continued to creep into by hoisting mechanism I5; Meanwhile, dynamic catwalk 2 carries next single drill pipe 10, sees Fig. 9.

The trip-out work flow of apparatus of the present invention is that its step comprises:

Step 1. hoisting mechanism I5 promotes drilling tool and goes upward to predetermined altitude, and meanwhile hoisting mechanism II9 empty down is to hoisting mechanism I5 upper unit, sees Figure 10.

Step 2. hoisting mechanism II9 slurry channel open and complete in hoisting mechanism I5 upper unit with drilling tool on pull do, hoisting mechanism I5 slurry channel closes; Hoisting mechanism I5 unclamps drilling tool and comes downwards to drilling floor surface, and meanwhile hoisting mechanism II9 takes drilling tool and goes upward to predetermined altitude, sees Figure 11.

Step 3. hoisting mechanism I5 upper unit completes the drilling tool shackle action of drilling floor surface place, and hoisting mechanism I5 slurry channel is opened, and hoisting mechanism II9 slurry channel is closed and a up segment distance, sees Figure 12.

Step 4. rigger 8 and pillar grab pipe machine 6 capture thribble, and top, hoisting mechanism II9 bottom is driven and unclamped drilling tool, sees Figure 13.

Step 5. automatically rigger 8, pillar tube drawbench 6 cooperatively interacts discharge thribble, and meanwhile hoisting mechanism I5, hoisting mechanism II9 continue next thribble that pulls out of hole, and see Figure 14.

Tripping operation flow process of the present invention is the inverse process of trip-out flow process, no longer repeats at this.

Full-automatic drilling rig continuously of the present invention, improve the safety of operating personnel, whole drilling operation course achieves full-automation, without the need to floorman and rigger, operation can complete rectification drilling well and round trip in control room only to need operating personnel, can avoid injury to personnel; Improve drilling efficiency, achieve in whole drilling process and make a trip continuously and creep into, need not on unload drilling rod and stop boring, can brill limit, limit stacks, greatly improve drilling efficiency.Improve the safety of well bore, the uninterrupted circulation of drilling fluid and making a trip continuously and at the uniform velocity can reduce the wellbore pressure fluctuation that swabbing action causes, and is conducive to maintaining wellbore stability, reduces the possibility that complex situations occur in down-hole.
