Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.

As depicted in figs. 1 and 2, be the structural representation of the continuous running and pulling device of the utility model rig, the continuous running and pulling device of this rig comprises that the inner side of 1,2 twin-well frame 1 of 2 twin-well framves is connected; In each twin-well frame 1, be equipped with a tubing string Hoisting System, this tubing string Hoisting System comprises tubing string lift structure and is attached thereto the steel structure frame 9 connecing, tubing string lift structure comprises the overhead traveling crane 2, tourist bus 3 and the hook 4 that connect successively, and wherein hook 4 is connected with steel structure frame 9.In steel structure frame 9, be provided with and be attached thereto the top connecing and drive 7, and top is driven 7 and is connected with steel structure frame 9 by hydraulic arm 10.Steel structure frame 9 is connected with derrick guide rail 12 by slide block 6, vertically moving.Steel structure frame 9 also promotes unscrewing device 8 by hydraulic arm 10 and tubing string and is connected, for connecting and fixing tubing string.Tubing string in 2 tubing string Hoisting System promotes unscrewing device 8 and vertically arranges, and is located along the same line.In each twin-well frame 1, be provided with a tubing string board migration device 11, the tubing string 13 of carrying for transferring tubing string Hoisting System.

In the continuous running and pulling device of the utility model rig, as the case may be, tubing string lift structure also can adopt respectively hydraulic lifting apparatus, pinion and-rack lifting appliance or chain type lifting appliance.

The work of the continuous running and pulling device of the utility model rig is as follows:

1, promote tubing string

In the time that the tubing string lifting unscrewing device 8 of Hoisting System A is tripping out tubing string 13 from well center, the tubing string of Hoisting System B promote correct position that unscrewing device 8 moves downward rig floor at " retrieving position " wait for Hoisting System A by complete tubing string 13 upright liftings to more than drilling floor surface, when tubing string 13 joints are by after rotating disk, the tubing string of Hoisting System B promotes unscrewing device 8 and moves on to well center, in the time that tubing string lifting unscrewing device 8 is caught tubing string 13 joint, Hoisting System B starts together to move upward with tubing string 13, in the process of motion, the tubing string of Hoisting System B promotes the weight that unscrewing device 8 starts shackle and born the whole tubing string 13 in bottom by the tubing string lifting appliance that the tubing string of Hoisting System B promotes unscrewing device 8 under the acting in conjunction of upper shackle device and tubing string lifting appliance, shackle finishes, Hoisting System B discharges the column tripping out, the tubing string of Hoisting System A promotes unscrewing device 8 and gets back to " retrieving position " with the tubing string 13 tripping out, corresponding tubing string board migration device 11 is caught the tubing string 13 tripping out, Hoisting System A discharges the tubing string 13 tripping out, tubing string board migration device 11 moves to tubing string on fingerboard 14, at this simultaneously, Hoisting System A starts to move downward, start new circulation.

2, transfer tubing string

In the time that the tubing string lifting unscrewing device 8 of Hoisting System A is being transferred tubing string 13 toward well center, the tubing string of Hoisting System B promotes unscrewing device 8 and moves upward to correct position at " retrieving position ", and from corresponding tubing string board migration device 11, take over tubing string 13 columns, when Hoisting System A moves to while soon approaching rotating disk, the tubing string of Hoisting System B promotes unscrewing device 8 and reaches well center, and start to move downward, the lower end joint of new column is in motion process, the upper shackle device and the tubing string lifting appliance that are promoted unscrewing device 8 by the tubing string of Hoisting System A complete upper button jointly, then Hoisting System B continues to transfer new tubing string 13 columns, the tubing string of Hoisting System A promotes unscrewing device 8 and discharges tubing string 13, and get back to " retrieving position " and start to move upward, start new circulation.

The continuous running and pulling device of the utility model rig is specially adapted to deep water rig, and two cover Hoisting System have realized carrying out continuously of tubing string rountrip, can greatly improve operating efficiency, reduce operating cost, reduce down-hole accident, save operating personnel's quantity.In addition, due to the redundancy of two cover Hoisting System, in the time that wherein a set of Hoisting System breaks down, can directly proceed to conventional rig pattern, reduce the probability of the non-activity duration generation causing due to Hoisting System fault.
