  • a workover rig 10 is broadly comprised of a derrick 12 mounted on a work floor 13 above a base structure made up of one or more housings 14 adapted to be mounted on elongated skids or guideways 16 .
  • the guideways 16 are arranged in pairs to flank one or more rows of wellheads represented at W in FIGS. 1 and 5 .
  • the wellheads W may be for gas wells in which directional drilling has enabled the wellheads W to be spaced very short distances apart, such as, on the order of 3 to 6 feet.
  • Fluid-actuated, double-acting cylinders 18 are mounted behind the base structure housings 14 on each pair of skids 16 for the purpose of advancing the rig 10 along the row or rows of wellheads W.
  • Standard snub cylinders S are also positioned on the work floor 13 and hydraulically controlled through a main control panel to be hereinafter described.
  • the derrick 12 supports a main lift cylinder 20 mounted over a center bore 21 at one end of a work floor or platform 13 , and lateral adjustment cylinders 22 are engageable with a slidable derrick plate 24 to accurately align the main lift cylinder 20 on the derrick 12 over the well to be serviced or completed.

  • FIG. 13 illustrates the catwalk 48 and grating spacer assembly mounted on the base structure as represented by the rectangular housing members 14 .
  • upper beams 49 extend along the entire length of the base structure and securely anchor the upper work floor 13 hereinabove described to the housing members 14 .
  • the housing members 14 are made up of large shipping containers on the order of 8 feet wide by 20 feet long.
  • the shipping containers 14 are of elongated, rectangular configuration and each pair is mounted in end-to-end relation to one another with a grade bolt 50 between adjoining ends of the beams 49 to interconnect each pair of containers 14 into flush, aligned relation to one another.
  • each pair of skids 16 is rigidly interconnected by crosstube members 17 at spaced intervals along the entire length of the skids 16 .
  • low-friction shoes 58 each include an upper guide plate or rod 59 inserted into a recess 60 in the undersurface of the front and rear corner of each of the housing members 14 so that the entire weight of the housing members 14 is applied through the slide members 58 to the skids 16 .
  • Low-friction plastic insert plates 61 are positioned between each shoe and skid to enable the entire rig to slide easily along the guideways or skids 16 with a minimum of friction.
  • a double-acting cylinder 62 includes a piston rod 63 bearing against a stop 64 which is adjustably positioned on the skid by an adjustment bolt 66 , and the opposite end of the cylinder 62 is affixed to a pusher 66 in direct proximity to and behind one of the corner slides 58 .

  • the housing members 14 When fluid under pressure is applied in a direction causing extension of the cylinder 62 away from the stop 64 , the housing members 14 will be advanced a distance corresponding to the axial movement of the cylinder 62 , bearing in mind that the four cylinders 62 will be activated in unison behind the housing members to advance them along the skids 16 . Also, the housing members 14 will be advanced incrementally by successively advancing and retracting the cylinders 62 and moving the stops 64 and 66 to the next adjustment opening 65 .
  • FIGS. 14 to 19 are detailed views of the catwalk 48 and grating spacers 50 and 54 , the grating spacers 50 extending between the catwalk 48 and a pipe rack section 51 .
  • the catwalk as illustrated in FIG. 14 , is comprised of grating 145 supported on gusset I-beams 146 between rails 148 extending length-wise on opposite sides of the catwalk, and the catwalk 48 is positioned between the crossbeams 46 and the first grating spacer 50 .
  • the grating support spacers 50 and 54 are correspondingly made up of two-inch square tubing support members 156 underlying a grate 158 and joined to angle irons 159 at the four corners of the grate 158 .
  • the pipe rack sections 51 and 52 shown in FIGS. 17 to 19 overly portions of the catwalk 48 and, as shown in FIGS. 1 and 13 , extend along both sides of the derrick 12 so that the pipe sections P may extend lengthwise of the catwalks.
  • Both sections correspondingly include a rectangular grating 161 which is reinforced by I-beams 172 and square tubes 173 across the undersurface of the grating 161 as illustrated.
  • a flat plate 74 is mounted on the grating 171 , as best seen from FIG. 18 ; and

  • One of the I-beams 72 is centered between opposite sides of each pipe rack section, and a lift stop support 80 extends upwardly from the plate 74 to limit downward movement of the lift bracket 76 .
  • the derrick 12 is mounted at one end of the work floor 13 on the derrick slide plate 24 with the generally U-shaped open front side of the derrick 12 facing the pipe racks 51 and 52 , and the cylinder 20 is aligned vertically with respect to the center bore 21 over the wellhead W.
  • FIG. 12 illustrates the base 44 of the derrick in exploded form, it is centered on the derrick slide plate 24 and has its center opening 45 aligned directly over the center bore 21 . In this way, the derrick 12 will follow the shifting of the slide plate 24 in aligning the center bore 21 over the wellhead W to be serviced.
  • the slide plate 24 is mounted on low-friction plates 25 and is advanced by a pair of double-acting cylinders 81 in spaced parallel relation to one another on the work floor, the end of the cylinders 80 being anchored by a pair of bolts 82 through a spaced pair of openings in each cylinder 81 which are aligned with two matching openings 84 in the slide plate 24 .
  • Additional openings 86 are provided in the slide plate 24 for mounting the base plate 44 of the derrick 12 by suitable fasteners, not shown.
  • Piston rods 88 at the opposite ends of the cylinders 80 are anchored by bolts 89 to base plates 90 so that the cylinders 80 are free to advance and retract the slide plates 24 and 44 in a lateral direction across the end of the work floor 13 .
  • Removable stops 91 are insertable into openings 92 which are at staggered intervals from the side edge of the work floor 13 to shift the path of movement of the slide plates 24 and 44 with respect to the work floor 13 and the ground in vertically aligning the center bores 21 and 45 over each wellhead W in succession.
  • FIG. 21 schematically illustrates a flow control valve 101 for the lift cylinder 20 , the valve 102 for a standard rotary table control mounted over the slide plates 21 and 44 , and pressure relief valves 104 for the lift cylinder 20 , rotary table, snub cylinders S and the conventional upper and lower slips on the work basket.

  • a flywheel and shaft 128 are mounted on the gear box 130 of the engine 132 .
  • the engine for example, may be a Detroit 8V92 575 horsepower (Detroit Diesel, Detroit, Mich.), and utilizes a three-stage commercial gear pump with three relief valves.
  • the gear box may be a Durst PH 9 (Durst, Shopiere, Wis.).
  • a series of Denison vane pumps (Parker Hannifin HPD, Marysville, Ohio) are provided off of the engine together with 3000 psi relief valves.
  • the complete engine power pack may be stored in one of the containers 14 , the pumps housed in another container 14 , the reservoir or tank in one of the containers 14 , and the remaining container 14 being utilized as a tool house. In this way, the various engine, pump, and control components will contribute to the weight necessary to stabilize the entire rig and establish a low center of gravity to more than counterbalance the weight of the derrick 12 , pipe sections P and lift cylinder 20 .
  • each pipe section P is stacked on top of the pipe racks 51 and 52 with their ends in facing relation to the derrick 12 .
  • Each pipe section P is raised either manually or with the assistance of the pipe bracket 76 in order to wrap the winch cable, not shown, around the end of the pipe and advance the pipe over to the work basket where it is lined up beneath the elevators 99 on the lift cylinder 20 .
  • the end of each pipe section P is engaged by the elevators 99 and lifted until the pipe P is vertically aligned with the center of the well.
  • the snub cylinders S are used only in situations where there is some pressure in the hole, but normally the lift cylinder 20 is used throughout the entire process in lifting and lowering each pipe section into and from the well.
  • the three-stage pump 122 is controlled by the bank of controls on the control panel, one of the pumps having one side that controls the snub cylinders S when necessary. All three pumps can be activated together as needed to supply the necessary fluid under pressure to the main lift cylinder 20 via the flow control valves 101 - 103 and the directional control valve 95 .
  • One of the pumps is also connected to the rotary drive table.
  • the open or U-shaped front of the derrick enables automated lifting of each pipe section by the cylinder 20 through an angular path of movement from the pipe racks up to the top of the derrick until the pipe section becomes aligned with the wellhead.
  • the upper and lower slip bowls are of standard construction and, for example, may be Cavins slip bowls (Cavins, Signal Hill, Calif.) At this point, it will be apparent that standard procedure can be followed in successively lowering each pipe section into the well with the aid of the slip bowls.
  • the hydraulic control circuit for the pusher cylinders is represented in FIG. 7 and includes a two-bank control 132 in order to simultaneously activate the cylinders 62 behind the containers 14 .
  • the cylinders 62 are push-pull cylinders to advanced the entire base structure in either direction along the guideways.
  • a pair of handle controls, not shown, may be mounted on the end of the one of the containers 14 to control the flow of fluid from one of the pumps referred to in FIG. 25 to activate the cylinders 62 as referred to earlier. If necessary, the derrick slide plate is activated to adjust the derrick laterally into alignment over the well to be serviced.
  • FIG. 26 An offshore drilling 10 ′ is illustrated in FIG. 26 wherein like parts are correspondingly enumerated with prime numerals.
  • the rig 10 ′ is made up of a derrick 12 ′ mounted on base housing members or containers, not shown, which can be affixed or mounted on the standard offshore drilling platform, not shown, and therefore can utilize the existing positioning controls on the drilling platform to advance the derrick into position for the workover operation.
  • the work floor 13 ′ has the same components including the catwalk, grating spacers, and pipe racks as described in the first embodiment.
