The drilling rig 10 also has a surface for handling the pulls 28. This area bears the reference number 30 and is shown as part of the base part 16 in FIG. 1A. The area 3O is offset from the center line of the borehole so that the trains 28 in the drilling rig 10 can be handled there, where the operations involved do not interfere with operations being carried out along the center line of the borehole.

Longer tracks or guides 32 are attached to the derrick 12 and extend over a substantial portion of the derrick 12. The tracks 32 are for adjusting the position of the running block 34 and an elevator 36, which is connected to the lower end of the barrel block 34.

The barrel block 34 is connected to the elevator (not shown) via a Cable system 38 connected, which extends from the barrel block 34 to extends above a crown block 4O, which at the upper end of the derrick 12 is arranged. The cable system 38 enables the running block 34 to be raised and lowered longitudinally in the derrick 12 of track 32.

The drilling rig 10 has an upper pipe handling device and a lower pipe handling device 44. Like in the Fig. 1b shown, the upper pipe handling device on a frame 46, the a pair in the spacing ratio present Track parts 48 and 50 carries. An upper transfer arm assembly 52 is movably provided on tracks 48 and 50, uieliQ is shown individually in FIGS. 4 and 5.

The upper and lower beams 54 and 56 movably connect the transfer arm 52 to the tracks 48 and 50. The beams 54 and / or 56 may be provided with a motor or similar device for moving the transfer arm 52 along the tracks 48 and 50. Furthermore, either the upper or lower beam 54 or 56 will have a servomotor 58 for pivoting the transfer pan 52 relative to the rails 48 and 50. If necessary, the beams 54 and 56 can be connected to the rails 46 and 50 and the rails relative to the frame 46 be moved.

An outer part 60 extends between the beams 54 and 56. The outer part CD is in the form of a hollow beam

and is arranged to thereby movably support and pivot the lower end of a pair of links or members 62 the upper end of a second connector 64 is carried. The connecting parts 62 and 64 are pivotable by means of a Pin 66 connected.

The upper ends of the parts 62 are pivotable with the upper end an upper part of an inner end 68 connected, practically is arranged parallel to the outer part 60. The inner part 68 is also a hollow support and is arranged to movably support the lower end of the connector 64 therethrough.

The transfer arm 52 is a geoaetrische construction that occasionally referred to as a pantograph. This means that the design is chosen in such a way that the movement of the lower End of the connecting parts 62 and 64 leads to the fact that the connecting parts are pivoted about the pin 66, whereby the inner part 68 is moved relatively toward and away from the outer portion 60.

To assist in the movement of the ends of the connectors 62 and 64, is a linear actuator 70, such as a hydraulic one Cylinder arranged in the outer part 60 so that its lower end in connection with the lower ends of the connecting parts 62 stands. Actuation of the linear actuator 70 moves the lower ends of the joint 62 and 64 relatively towards the hinged upper ends, thereby moving the inner part 68 relative to the outer part 60 will. A steep pipe engagement 72 is movably arranged on the inner part 68. The pipe engaging part 72 has a recess 74 in its outer end part with an appropriate size for receiving the drill pipe. The recess 74 is arranged so that that the same fits over the pipe, but sufficiently small such that the enlarged coupling pieces which the pipe sections connect to form the pipe runs can not go through. Thus, the tube engaging part 72 can be engaged with the Collars are raised with an upward force being exerted on the pipe runs 28.

As can be seen from FIG. 2B, a cable system extends 76 from the pipe engaging parts 72 to a cable pulley 78 suspended in the derrick 12 and then to a lever mechanism (not shown). - 6.

109809/0270

The arrangement is such that the cable system along the inner part 68 of 72 may Uberführungsarms 76 for raising and lowering pipe as engaging portions 72 are applied, is raised and whereby the hereby-engaging train 28 lowered.

The lower pipe handler 44 includes a frame 80 which is connected to the derrick 12 and to the base 16 supporting a pair of spaced apart rails 82 and 84. It is a transfer jig 86 movably arranged on tracks 82 and 84. The transfer arm 86 is identical in practically every respect to the transfer arm 52 described above. The transfer arm 86 preferably includes a tube engaging portion 88 that is attached to the inner arm 63 and is not movable along the same is carried out as described above in connection with the transfer arm 52.

Based on the above, it follows that corresponding energy, such as electrical or hydraulic energy, the different Motors and actuators used in pipe handling devices 42 and 44 can be supplied. It is further preferred that the transfer arms 52 and 86 can be controlled for synchronous movement by an operator who has his workplace on the base part or stage 16. Such a control device has a conventional design and is therefore not explained in detail here.

FIG. 3 is a transverse view of the drilling turn 12 directly above the frame 46 in the downward direction of view. The track 50 will be in the derrick 12 and in approximately the same position as the drop weight of a conventional derrick. Handling fingers present in the spaced relationship extend into the frame 46 in the direction of the track 50 and result in a plurality of d handling slots 92. The fingers 90 are arranged directly above the surface 30.

The pipe handling devices 42 and 44 of the present invention are shown in FIG of the drilling rig 10 during removal of the drill pipe from the wellbore and replacement of the drill pipe. As the pipe handling

The elevator is operated, causing the cable system 38 to run the black 34 una the elevators 36 lowered until the elevators 35 at the upper end of the drill pipe 26, which extends from the Borehole from extend, can be attached. Then the cable system 33 is actuated by lifting the running block 34 and the Elevators 30 in the derrick 12, whereby the drilling column 26 hereby is raised. As soon as a train 23 of the drilling column 26 has been raised into the derrick 12, the safety wedges 22 are grounded in Thing reef and hold a drilling column 26 in a borehole of the same shape, that the train 28 extends from here.

The barrel block 34 is then lowered as soon as the feed 28 comes with it the remaining part of the Bohriolonne 26 connectue screw connection is unscrewed. While the Zuo 28 is being unscrewed, Were transferring arrae 52 and 86 to the inside of the building the center line of the borehole moves until the pipe engaging parts 72 and 83 have come into engagement with the train 28. Once the Cable 28 has been unscrewed from the drilling column 26, the cable system 76 is actuated and the pipe engaging part 72 is raised below Raise the train 23 away from the remainder of the drilling string 26th

Once the column 28 is free, the actuator is energized, causing the transfer arms 52 and 36 to collapse and the pull 28 is moved outwardly away from the centerline of the wellbore and toward the pipe handling area. the Transfer arms 52 and 86 and the attached pipe 28 are then positioned along the tracks in the appropriate handling moved over the surface. As in the Fiq. 6, the pipe engaging member 72 and train 23 are then pivoted and hydraulic Actuator energizes moving inner member 68 away from outer member 60 so that pull 26 is in the correct position Slot 92 is arranged between the handling fingers 90. The cable system 76 is then used to lower the train 28 and pipe engaging portion 72 to the lower end of the train 28 rests on the surface 30. Then the transfer can 52

and 86 are merged, returned to the surface of the centerline of the wellbore and in a practically aligned position Arranged length of track so as to accommodate subsequent pipe runs 28 as soon as the drilling column 26 is pulled out of the borehole will.

Since the angular position of the transfer arms 52 and 86 is controlled by a servomotor, it is not necessary for the barrel block 34 to be arranged on the guide 32. The ability to arrange the tube engaging member 72 in various angular positions enables it is an operator of the pipe handling devices 42 and 44 to look for the train 28 while it is hanging in the derrick 12.

While Fig. 6 shows the movement of the tube engaging member 72 only in the rightward direction, it should be understood that the pipe engaging part 72 can be pivoted to the left so as to utilize the handling area to the left of the tracks 48 and 50. Employing the collapsible mechanism built into transfer arms 52 and 86 enables the arms to be stable are carried out and are located on heavy tracks that do not affect the normal operations in the drilling rig 10 when the same are relatively short. It also enables the collapsible arrangement of the transfer arms that the transfer arms are pivoted in a relatively small area can, whereby 12 space is saved in the derrick.
