Definitions

  • the present invention relates to wireline borehole operations, particularly borehole logging and perforating operations using a stinger for extending, moving, and positioning wireline tools in highly deviated wells.
  • the above-noted '072 patent discloses another very successful method and apparatus for pulling the wireline cable through the drill pipe after the drill pipe has been assembled.
  • a full-sized wireline tool (usually too big to pass through the drill string) is releasably attached to the bottom end of the drill string.
  • a locomotive propelled by mud pressure in the drill string pulls both the wireline and the stinger through the drill string.
  • the stinger then docks on the upper end of the wireline tool, to make the mechanical and electrical connections and to propel the tool out of the drill string and into the borehole on the end of the stinger.
  • this invention averts the need to install the wireline through the entire length of the drill string as it is being assembled.
  • the present invention meets the above needs and purposes with a dual or two-stage locomotive which is capable of pulling a wireline cable through the entire length of both the drill string and the stinger after they have been fully assembled and placed in the borehole, with a full-sized tool attached to them at the bottom.
  • the two-stage locomotive system also basically pulls (rather than pushes) the stinger out into the borehole from the bottom end of the stinger, so that the risk of buckling is virtually eliminated.
  • the entire stinger and drill stem can therefore be assembled to virtually any length, without requiring any pre-wiring, thereby avoiding the attendant expense and/or inconvenience and delay of prior art methods and apparatus.
  • the special configuration provided by the present invention still effectively prevents the stinger from buckling.
  • Fig. 1 shows a borehole 10 having a highly deviated portion 12 traversing earth formations 15.
  • a conventional wireline tool 20 is shown mounted on the lower end 22 of a hollow extension member or stinger 25, opposite the upper end 27 thereof.
  • tool 20 is in fact attached to and supported by a docking head 30 at the end 22 of stinger 25.
  • Docking head 30 is releasably latched to the lower end 32 of a length of drill pipe 35 in which stinger 25 is extendably received for transportation by drill pipe 35 to the deviated borehole portion 12 of interest.
  • wireline tool 20 may be any conventional well-logging tool for logging earth formations surrounding borehole 10, or it may be a conventional well bore perforator, such as used during completion operations to perforate a cased borehole. It should therefore be understood that the term "wireline tool”, as used herein, is with reference to any borehole tool typically coupled to the surface equipment, such as the conventional surface equipment designated generally by reference numeral 38, through a well logging communication cable 40 more commonly known as a "wireiine".
  • the drill pipe 35 and stinger 25 may be assembled by any of the conventional means usually followed in deviated borehole operations employing a stinger carried within a drill pipe.
  • a stinger carried within a drill pipe Of significance to the present invention is the fact that the drill pipe and stinger, during and after their assembly and transportation to the deviated borehole portion 12, do not contain any lengths of wireline cable.
  • the steps for furnishing a cable within a stinger section such as disclosed in the above-noted '830 application, or the provision for a stinger which is pumped down from the surface with the cable following behind it, as in the above-noted '072 patent, are unnecessary.
  • the cable is not carried on the outside of the drill pipe or stinger where it might be exposed to abrasion and damage from contact with the borehole walls during the logging or perforating operation.
  • the present invention provides for bringing the wireline cable 40 to the wireline tool 20 and for extending the stinger 25 from the drill pipe 35 by means of a dual locomotive having a first locomotive portion 44 and a second locomotive portion 45.
  • the hollow length of stinger tubing 25 is free for movement upwardly and downwardly within the drill pipe 35 since the stinger has an outside diameter smaller than the inside diameter of the drill pipe 35 in which the present invention is to be used.
  • a first docking means 50 on the upper end 27 of stinger 25 is provided for receiving the first locomotive 44 thereon. While it is possible to provide for latching the first locomotive 44 and the first docking means 50 together, it will be seen, as the invention is further developed below, that this is not necessary, and that the first locomotive may simply seat upon the docking means 50.
  • a second docking means 55 is mounted on the lower end 22' of stinger 25.
  • the second docking means 55 which may be of any known suitable configuration, is adapted for receiving and coupling to the second locomotive 45 after locomotive 45 has passed through the interior of the hollow stinger tubing 25.
  • Docking means 55 is also adapted for making at least one electrical connection with the second locomotive 45 for completing the electrical circuit from the wireline cable 40 to the wireline tool 20.
  • the attaching of the wireline tool 20 to the second docking means 55 at the lower end 22 of stinger 25 may be accomplished, for example, through the lower docking head 30 to which the tool 20 is secured.
  • Docking head 30 and locomotive 45 each contain complementary wet matable connector portions 59a and b, of designs well known in the well logging art, for completing one or more of these electrical connections.
  • a releasable latching means 60 cooperatively latches the docking means 55 to the adjacent drill pipe 35, when docking means 55 is not coupled to second locomotive 45, to support the wireline tool 20 and stinger 25 within the lower end 32 of the drill pipe 35. Latching means 60 then also provides for releasing the second docking means 55 from the drill pipe 35 when coupled to locomotive 45.
  • the first locomotive 44 has a seal portion 64 which has an effective outside diameter substantially equal to the inside-diameter of the drill pipe 35 in which it is to be used. As indicated, first locomotive 44 is also adapted for engaging the first docking means 50, and as will be further explained hereinbelow, is moved to docking means 50 by the pressure of fluid flow within and through the drill pipe 35. Likewise, the second locomotive 45 includes a seal portion 65 having an effective outside diameter substantially equal to the inside diameter of the stinger tubing 25. Second locomotive 45 is similarly adapted, therefore, to be propelled through the stinger tubing 25 by the pressure of fluid flow therethrough. In .addition, first locomotive 44 contains a hollow recess 67 having a diameter substantially equal to the inside diameter of.
  • second locomotive 45 is adapted for. pulling the wireline cable 40 through the drill pipe 35, the first locomotive 44, and the stinger tubing 25, and for moving oeneath and independently of the first iocomotive 44 atter locomotive 4 4 has docked upon the first docking means 50.
  • the first locomotive 44 contains a fluid passage 70 which is comprised, in part, of the hollow recess 67 so that the fluid passage 70 is closed when the second locomotive 45 is positioned therein for movement with the first locomotive 44. Otherwise, when hollow recess 67 is open, the fluid passage 70 fluidly couples entirely through the first - locomotive 44, from each side of the seal portion 64, for conducting fluid therethrough and thereby equalizing the hydraulic pressures on each side of the locomotive 44. As may be seen in Fig. 4, this condition obtains especially when the first locomotive 44 is received upon the first docking means 50 at the upper end 27 of stinger 25.
  • locomotive 44 By equalizing the hydraulic pressures across the first locomotive 44 at this time, locomotive 44 provides essentially no pushing force or thrust upon the upper end 27 of stinger 25 as the stinger is being propelled out the end of the drill pipe 35. (The only pushing force, in fact, derives from the mud pressure upon the effective cross-sectional area of the upper end 27 of the stinger tubing 25.)
  • a stinger seal 73 below the first docking means 50 and preferably adjacent the lower end 32 of the drill pipe 35, movably seals the outside of the stinger tubing 25 to the inside of the drill pipe 35, to prevent fluid which is pumped into the drill pipe 35 from escaping around the outside of the stinger tubing 25. Instead, fluid pumped into the drill pipe will first propel both locomotives, starting from the upper end of the drill pipe 35 at the earth's surface, downwardly into the drill pipe until the first locomotive 44 reaches and seats upon the first docking means 50. At that time, the fluid pressure will continue propelling the second locomotive 45 downwardly through the inside of the stinger tubing 25 until the second locomotive reaches the second docking means 55.
  • locomotive 45 Upon reaching the second docking means 55, locomotive 45 will actuate the latching means 60 to release the stinger tubing 25 from the drill pipe 35 and couple the second locomotive 45 simultaneously to the latching means 60. Further fluid flow through the drill pipe 35 then urges or propels the second locomotive 45 further downwardly and outwardly of the drill pipe 35, causing the locomotive 45, since it is located at the lower end 22 of stinger 25, to pull the entire length of the stinger thereabove out of the bottom of the drill pipe 35.
  • substantially all of the force moving the stinger 25 and wireline tool 20 out of the drill pipe 35 and into position for the logging operation is applied by the second locomotive 45 at the bottom of the stinger, and is therefore a pulling force insofar as most of the stinger length is concerned.
  • the only force tending to push the stinger is the small force represented by the pressure on the effective cross-sectional area of the upper end 27 of the stinger tubing 25, due to the equalizing of the pressures across the first locomotive 44 by the fluid passage 70 therethrough.
  • a conventional logging or perforating operation may be performed.
  • the wireline cable 40 will be retrieved to move the tool 20 to the positions and at the rates desired to perform the logging operation.
  • the retrieving force is furnished by the pull and retracting of the wireline cable 40.
  • the stinger 25 at this time is being pushed back into the drill pipe 35 by the second locomotive 45 at the lower end 22 of stinger 25.
  • the stinger 25 is again protected by the present invention from buckling.
  • any tendency of the stinger 25 to buckle will result in the application of a lateral force to the wireline cable 40.
  • Such a force will serve only to further increase the tension on cable 40, which will not allow the stinger 25 to buckle. Since the deviation from "straight" at this point is but very slight, only a very small lateral force is. necessary to withstand tremendous longitudinal forces in the stinger to prevent it from buckling.
  • the second locomotive is uncoupled from the stinger tubing 25. Further retraction of the wireline cable 40 then pulls the second locomotive into the hollow recess 67 of first locomotive 44 causing locomotive 44 to be pushed upwardly by locomotive 45 as the latter is pulled upwardly by the wireline cable 40 attached to it.
  • the dual locomotives and wireline cable are thus fully retracted and removed from the stinger tubing and drill pipe to provide the maximum ease and convenience for subsequently repositioning the tool 20 by changing the length of the drill pipe 35, for adjusting the length of the stinger 25, or removing either or both from the borehole 10, as desired, without the necessity to accommodate a wireline cable.
  • the present invention has numerous advantages. Principally, it provides for convenient and rapid assembly of a stinger logging or perforating tubing and drill pipe assembly of virtually unlimited length for use in logging highly deviated wells. Additionally, due to the unique configuration of the dual locomotive propulsion system, the stinger is extended from the tubing by being pulled therefrom rather than pushed, and retraction is by means of a tensioned cable within the tubing such that the risk of buckling the tubing is virtually eliminated regardless of the tubing length.
  • Stingers of virtually any length can therefore be contemplated and readily accommodated by the present invention, and the wireline cable electrically connected to the wireline tool quickly, easily, with minimum expense, and in a manner which effectively shields the cable from exposure to any damage in the borehole.
