Abstract

1393388 Drilling wells RUSTON-BUCYRUS LTD 17 Aug 1972 [20 Aug 1971 (2)] 38368/72 Heading E1F A method of drilling a well and inserting a casing 7 comprises transferring a drill pipe segment 6 with a surrounding casing segment from storage to a vertical drilling position; connecting the drill and casing segments to a drive unit 32; and rotating the drill segment by means of the drive unit while simultaneously applying a downward feed force on the casing segment by means of the drive unit to insert it into the well as the well is being drilled. Drill-casing segments 6, 7 are hoisted by means of a transfer arm 4, Fig 1, and mandibles 23, 24 from a horizontal storage position on a wheeled truck 1 to a vertical drilling position, wherein the upper ends of both the drill and casing segments are attached to the drive unit 32 on a mast 2. The lower end of the drill segment 6 is screwed into the top end of a drill string in the bore hole, and the lower end of the casing segment 7 is welded to the top end of a casing in the bore hole. The drill and casing elements are both driven into the ground by the drive unit 32 which is propelled downwardly along tracks on the mast 2. The drive unit 32 comprises a rotary drive section 34 having a rotatable spindle 36 which is screwed into the upper, end of the drill segment 6 and rotates the drill string, and a chuck section 35 which grips the upper end of the casing segment 7 and is provided with stop bars 149, Fig 9, to contact the upper edge of the casing segment. The jaws 150 of the chuck section are operated by hydraulic pistons 153 and cams 151, and a vibrator 157 is provided to enhance the insertion of the casing during drilling. In view of the vibratory nature of the chuck section 35, it is connected to the underside of the rotary drive section 34 by means of a floating ring 38 interposed between stacks 127, 129 of elastomeric material. A wrenching mechanism (37), Figure 18 (not shown), retains the protruding top end of the drill string while the threaded lower end of the drill segment is screwed therinto by rotation of the spindle 36.
