Definitions

  • the invention relates generally to the use of strings of coiled tubing to dispose flow actuated pumps into a wellbore and operation of such pumps.
  • Downhole pumps are used to pump hydrocarbon fluids and/or water from subterranean locations.
  • Electric submersible pumps (“ESPs") require electrical power to be supplied to them from surface.
  • a typical ESP assembly includes a centrifugal pump that is mounted to an electrical motor.
  • a power cable extends from the surface to the motor of the ESP assembly.
  • Flow actuated pumps are also known which utilize a piston or plunger to flow fluid, as opposed to a centrifugal pumping mechanism.
  • a flow actuated pump is described in U.S. Patent No. 7,789,131 entitled “Hydraulic Pump System for Deliquifying Low Rate Gas Wells.”
  • the 131 patent is owned by the assignee of the present invention.
  • the flow actuated pump described in the 131 patent uses a power fluid supplied from surface to operate the pumping mechanism rather than electrical power.
  • Most flow actuated pumps return exhausted power fluid with the wellbore fluid (water, gas, etc.) being produced.
  • some flow actuated pumps may have separate outputs for the exhausted power fluid and the wellbore fluid.
  • Dual-walled piping has been used in subsea applications to raise production fluid from a pump located on a seabed and not directly into a well. Such an arrangement is described in U.S. Patent Publication 2003/0170077 by Herd et al .
  • dual-walled coiled tubing has not heretofore been successfully used in subterranean wellbores in conjunction with fluid driven or flow actuated pumps or for dewatering gas wells.
  • the high pressure, high temperature conditions associated with a subterranean wellbore make the use of risers and flexible tubing impractical.
  • WO 2009/105501 A2 refers to an apparatus for producing fluids in a wellbore wherein gas is produced through one annular space and fluids are produced through a separate space.
  • the apparatus comprises a casing in the wellbore and a production tubing within the casing.
  • a hydraulically driven downhole pump is located within the production tubing and attached to a distal end of a multi-channel coiled tubing string that extends to the surface of the borehole.
  • High pressure hydraulic fluid is provided into a first channel within the multi-channel coiled tubing string.
  • Return hydraulic fluid is flowed through a second channel within the multi-channel coiled tubing string.
  • the first and second channels within the multi-channel coiled tubing string define a closed loop hydraulic fluid system where hydraulic fluid is not mixed with production fluids.
  • US 2013/0022480 A1 refers to devices and methods for recovering production fluid from a subterranean formation using a mechanical-hydraulic production system.
  • the mechanical-hydraulic production system includes a power fluid pump, a production fluid pump and a hydraulically-actuated motor that is associated with the production fluid pump to actuate the production fluid pump.
  • the power fluid pump is mechanically driven from the surface to fluid hydraulic power fluid to the motor, thereby driving the production fluid pump to pump production fluid.
  • the pumping systems comprise multiple coiled tubing strings.
  • CN 104 141 463 B discloses a device and a method for negative-pressure sand draining of a horizontal well by utilizing concentric double-layer coiled tubing to drag an injection pump.
  • the device comprises small-diameter coiled tubing and large-diameter coiled tubing, the small-diameter coiled tubing concentrically penetrates through the large-diameter coiled tubing, the lower end of the small-diameter coiled tubing is connected with the injection pump, and the lower end of the large-diameter coiled tubing is connected with a centralizer.
  • the invention provides a system and a method for disposing a flow actuated pump into a wellbore using running arrangements which incorporate a dual-walled coiled tubing running string having inner and outer coiled tubing strings as set forth in independent claims 1 and 4.
  • Fluid pumping arrangements are described in which the dual-walled coiled tubing running string supports the flow actuated pump and provides first and second fluid flow paths for fluid communication between the pump and the surface.
  • An annulus is defined between the outer coiled tubing string and the wall of the wellbore. The annulus serves as a third fluid flow path for the fluid pumping arrangements.
  • the flow actuated pump is interconnected with the running string so that power fluid is provided to the pump via the first fluid flow path and the production fluid is returned via the second fluid flow path. Exhausted power fluid is returned via the third fluid flow path.
  • dual-walled is intended to refer broadly to arrangements wherein an inner tubular string or member is located radially within an outer tubular string or member to provide a dual-walled tubing structure.
  • a structure can be dual-walled without regard to whether the inner and outer tubular strings are coaxial or 5 concentric.
  • Figure 1 depicts an exemplary wellbore 10 that has been drilled through the earth 12 from the surface 14 down to a hydrocarbon-bearing formation 16. It is desired to pump fluids from the formation 16 to the surface 14. It is noted that, while wellbore 10 is illustrated as a substantially vertical wellbore, it might, in practice, have portions that are inclined or horizontally-oriented.
  • the wellbore 10 is lined with metallic casing 18 in a manner known in the art. Perforations 20 pass through the casing 18 and into the formation 16.
  • the formation 16 is a gas formation which contains water 22. It is desired to remove the water 22 from the formation 16.
  • a fluid pumping arrangement is disposed within the wellbore 10.
  • the fluid pumping arrangement 20 is used to remove fluids from a subterranean location, such as formation 16. In the depicted embodiment, it is desired to pump the water 22 from the wellbore 10 to surface 14.
  • a fluid pump 26 is located at the surface 14 and is operable to pump fluid down through the fluid pumping assembly 24.
  • the fluid pumping arrangement 24 includes a flow actuated pump 28 and a dual-walled coiled tubing running string 30.
  • the flow actuated pump 28 is a non-electric fluid pump that is hydraulically-powered by a power fluid which is pumped by pump 26 from surface 14.
  • the flow actuated pump 28 may be a pump of the type described in U.S. Patent No. 7,789,131 entitled "Hydraulic Pump System for Deliquifying Low Rate Gas Wells.”
  • the '131 patent is owned by the assignee of the present application/patent.
  • the pump described in the 131 patent will return exhausted power fluid intermingled with the wellbore fluid being produced. As a result, it only requires a single flow path back to the surface 14.
  • the flow actuated pump 28 is a pump which operates by returning the exhausted power fluid and the produced fluid separately. In that case, the pump 28 would require two separate flow paths back to the surface 14. In operation, water 22 is drawn into fluid inlets 32 of the flow actuated pump 28 and exits proximate the upper axial end of the pump 28 as will be described.
  • the dual-walled coiled tubing running string 30 includes an inner coiled tubing string 34 and an outer coiled tubing string 36 which radially surrounds the inner coiled tubing string 34.
  • the inner coiled tubing string 34 defines a central axial fluid flow path along its length.
  • a first fluid flow path 38 is in turn defined along this central axial fluid flow path.
  • the outer coiled tubing string 36 defines an outer coiled tubing fluid flow path along its length, and a second fluid flow path 40 is defined radially between the inner and outer coiled tubing strings 34, 36.
  • Exemplary sizes for the inner and outer coiled tubing strings 34, 36 are: 1.25" O.D.
  • the inner and outer coiled tubing strings 34, 36 are normally connected together mechanically at surface and downhole ends and both would be hung off from the wellhead. Therefore, both strings 34, 36 may aid in supporting the weight of the flow actuated pump 28 as well as the inner and outer coiled tubing strings 34, 36.
  • a third fluid flow path 42 is formed by the annulus between the outer coiled tubing string 36 and the casing 18. The presence of three separate fluid flow paths 38, 40 and 42 allows for a power fluid, used to actuate the flow actuated pump 28, to be flowed down to the flow actuated pump 28 and returned to surface 14.
  • Figure 2 illustrates a first exemplary fluid pumping arrangement not part of the scope of protection, wherein a power fluid, used to actuate the flow actuated pump 28, is flowed down through the first fluid flow path 38, as indicated by arrow 44. Exhausted power fluid is flowed back to the surface 14 via the second fluid flow path 40 (arrow 46). Water 22 is flowed to surface 14 via the third fluid flow path 42, as indicated by arrow 48.
  • the flow actuated pump 28 is of the type which provides only a single output for intermingled water 22 and power fluid
  • either or both of the second and third flow paths 40, 42 may be used to return the commingled fluid to the surface 14.
  • power fluid is flowed down through the first fluid flow path 38.
  • Water 22 is flowed to surface 14 via the second fluid flow path 40.
  • Exhausted power fluid is flowed back to the surface 14 via the third fluid flow path 42.
  • the flow actuated pump 28 is of the type which provides only a single output for intermingled water 22 and power fluid, either or both of the second and third flow paths 40, 42 may be used to return the commingled fluid to the surface 14.
  • An assembled dual-walled coiled tubing assembly 30 can be wound onto a coiled tubing reel of a type known in the art for retaining spools of coiled tubing and transported to a well site for use.
  • a flow actuated pump assembly, such as pump 28, is then affixed to the coiled tubing assembly 30 and run into the wellbore 10 in conventional fashion.
  • the dual-walled coiled tubing assembly 30 may be assembled by inserting the inner coiled tubing string 34 into the outer coiled tubing string 36.
  • An assembled dual-walled coiled tubing assembly 30 can be wound onto a coiled tubing reel of a type known in the art for retaining spools of coiled tubing and transported to a well site for use.
  • a flow actuated pump 28 is then affixed to the coiled tubing assembly 30 and run into the wellbore 10.
  • the invention provides methods of pumping fluid from a subterranean location in a wellbore.
  • a fluid pumping arrangement 24 is disposed into a wellbore 10 so that the pump 28 is located proximate the formation 16 from which it is desired to remove liquid (water 22).
  • Power fluid is then pumped by pump 26 through the first fluid flow path 38 to the pump 28 to actuate the pump 28 to flow water 22 to surface 14 via the second flow path 40. Exhausted power fluid is returned to surface 14 via the third flow path 42.
  • Figure 4 illustrates an exemplary fluid pumping arrangement 50 which is being used for artificial lift of hydrocarbon production fluid from a wellbore 10.
  • the fluid pumping arrangement 50 of Figure 4 includes a packer 52 which is set against the casing 18 to isolate the flow actuated pump 28 below the packer 52.
  • the flow actuated pump 28 of the fluid pumping arrangement 28 is carried by dual-walled coiled tubing running string assembly 30.
  • the dual-walled coiled tubing assembly 30 includes an inner coiled tubing string 34 and an outer coiled tubing string 36.
  • the flow actuated pump 28 is of the type which provides a fluid output which is commingled exhausted power fluid and well fluid to be produced.
  • a first fluid flow path 38 is defined radially within the inner coiled tubing string 34
  • a second fluid flow path 40 is defined radially between the inner coiled tubing string 34 and the outer coiled tubing string 36.
  • the exemplary pumping arrangement 50 allows for zonal isolation within wellbores and permits fluids to be readily flowed past a packer 52 within a wellbore 10.
  • the flow actuated pump 28 can be installed at a certain depth and one or more packers 52 are used to isolate well fluids above and below the flow actuated pump 28. Well fluids below the packer 52 can be lifted by the flow actuated pump 28 past the packer 52 via the second flow path 40.
