Drilling well in whole drilling process can be realized by the cooperation of hoisting mechanism I5, hoisting mechanism II9, mud line manifold 12 The circulation of liquid is uninterrupted, continuously makes a trip and creeps into.

Tube drawbench 15, dynamic catwalk 2, hoisting mechanism I5, pillar grab pipe machine 6, automatic rigger 8 and hoisting mechanism II9 With the UNICOM of electrohydraulic controlling mechanism 19, electrohydraulic controlling mechanism 19 is integrated in the hydraulic station 20 on ground.

Above-mentioned tube drawbench 15, dynamic catwalk 2, hoisting mechanism I5, pillar grab pipe machine 6, automatic rigger 8 and hoisting mechanism Corresponding position sensor is provided with II9 executing agency, for position detection or spacing control, all position sensings Device is connected with the signal of electrohydraulic controlling mechanism 19, and utilizes the action of each execution unit in 19 pairs of covering devices of electrohydraulic controlling mechanism Carry out PLC technology so that control has safety interlock function, can also be by control room 3 to all parts remote control.

The drilling flow of apparatus of the present invention, implements according to following steps:

Step 1. hoisting mechanism I5 and hoisting mechanism II9 is in low level, and operation tube drawbench 15 rolls into single drill pipe 10 Dynamic catwalk 2, at the same time, hoisting mechanism I5 slurry channels are opened, hoisting mechanism II9 slurry channels are closed, hoisting mechanism II9 The shackle for stop drilling, completing with drilling tool is acted, and hoisting mechanism I5 starts drilling, sees Fig. 4.

Single drill pipe 10 is sent at pillar grab pipe machine 6 by step 2. dynamic catwalk 2;At the same time, on hoisting mechanism II9 Certain altitude is risen to, hoisting mechanism I5 continues to creep into, and sees Fig. 5.

Step 3. pillar grab pipe machine 6 captures single drill pipe 10, is changed into plumbness and is promoted to certain altitude submitting Hoisting mechanism II9 is given, hoisting mechanism II9 bottoms top is driven to complete to detain with single drill pipe 10;At the same time, hoisting mechanism I5 continues Drilling, dynamic catwalk 2 is descending to be resetted, and sees Fig. 6.

Step 4. hoisting mechanism II9 takes single drill pipe 10 and is displaced downwardly to hoisting mechanism I5, and hoisting mechanism II9 slurry channels are beaten Open and complete to pull work, hoisting mechanism on single drill pipe 10 and the drilling tool crept into hoisting mechanism I5 upper unit I5 closes slurry channel, stops drilling, and hoisting mechanism II9 starts drilling well, sees Fig. 7.

Step 5. is in same track, and hoisting mechanism I5 is all the time under, and hoisting mechanism II9 is all the time in upper, hoisting mechanism I5 Unclamp drilling tool and go upward to predetermined altitude, while hoisting mechanism II9 continues drilling well, see Fig. 8.

When step 6. hoisting mechanism II9 is crept into close to hoisting mechanism I5 upper units, hoisting mechanism II9 stoppings drilling, Complete the shackle with drilling tool to act, hoisting mechanism I5 slurry channels are opened, hoisting mechanism II9 slurry channels are closed, by elevator Structure I5 continues to creep into;At the same time, dynamic catwalk 2 conveys next single drill pipe 10, sees Fig. 9.

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

Step 1. hoisting mechanism I5 lifting drilling tools go upward to predetermined altitude, and at the same time hoisting mechanism II9 empty downs are extremely Hoisting mechanism I5 upper units, are shown in Figure 10.

Step 2. hoisting mechanism II9 slurry channels are opened and the upper button with drilling tool are completed in hoisting mechanism I5 upper units Action, hoisting mechanism I5 slurry channels are closed;Hoisting mechanism I5 unclamps drilling tool and comes downwards to drilling floor surface, at the same time hoisting mechanism II9 takes drilling tool and goes upward to predetermined altitude, sees Figure 11.

Step 3. hoisting mechanism I5 upper units complete drilling tool shackle action at drilling floor surface, and hoisting mechanism I5 slurry channels are beaten Open, hoisting mechanism II9 slurry channels are closed and a up segment distance, see Figure 12.

Step 4. rigger 8 and the crawl thribble of pillar grab pipe machine 6, hoisting mechanism II9 bottoms top, which is driven, unclamps drilling tool, sees figure 13。

The automatic rigger 8 of step 5., pillar tube drawbench 6, which cooperate, discharges thribble, at the same time hoisting mechanism I5, lifting Mechanism II9 continues next thribble that pulls out of hole, and sees Figure 14.

The tripping operation flow of the present invention is the inverse process of trip-out flow, is not repeated herein.

The full-automatic continuous drilling rig of the present invention, improves the security of operating personnel, and whole drilling operation course is realized Full-automation, without floorman and rigger, only needs operating personnel to complete rectification drilling well in control room operation and remove Operation is bored, injury to personnel can be avoided;Improve to realize in drilling efficiency, whole drilling process and continuously make a trip and creep into, no Stop brill with above to unload drilling rod, drilling efficiency can be greatly improved with the stacks when boring.Improve the security of well bore, drilling fluid Uninterrupted circulation and continuous and at the uniform velocity make a trip and can reduce wellbore pressure caused by swabbing action and fluctuate, be conducive to maintaining the borehole wall It is stable, reduce the possibility that complex situations occur for underground.
