Definitions

  • the present invention concerns a fluid pumping device to be installed in an offshore facility on a body of water to pump fluid from or to the offshore fluid facility.
  • the invention also concerns an offshore fluid production or/and injection facility comprising such a pumping device, and a method of pumping fluid in an offshore facility.
  • An offshore production site generally comprises fluid collection equipment located at the bottom of a body of water for collecting fluid from wellbores drilled through a subterranean reservoir. Numerous fluid injection and/or production lines extend through the body of water, through which the fluid flows to a surface installation.
  • a well pump equipment is required to provide an artificial lift for the wellbore fluids.
  • Well pumps are generally placed at a lower point in the well. They are electrically or hydraulically powered, which requires that utilities are provided to the well.
  • fluid pumping requires energy, which is often produced with combustion of the produced fluid. This leads to production of greenhouse gasses, which should be decreased.
  • One aim of the invention is thus to provide a fluid pumping device for an offshore facility, which requires low capital expenditures, while having a reduced carbon footprint and, in particular, which does not require self-consumption of the fluid pumped.
  • one subject matter of the invention is a fluid pumping device, characterized by:
  • the fluid pumping device may comprise one or more of the following feature(s), taken solely, or according to any technical feasible combination:
  • Another subject matter of the invention is a fluid production or/and injection facility extending in a body of water, comprising:
  • the facility according to the invention may comprise one or more of the following feature(s), taken solely, or according to any technical feasible combination:
  • Yet another subject matter of the invention is a method of pumping fluid in an offshore facility on a body of water comprising:
  • the method according to the invention may comprise the following feature:
  • Figure 1 illustrates a first offshore fluid production or/and injection facility 10 located in a body of water 35.
  • the facility 10 comprises a surface installation 15 positioned above at least a fluid production well 20 bored in the underground below a bottom 45 of the body of water 35, and a pumping device 25 configured for pumping fluid from a fluid reservoir (not represented) in the underground through the well 20 and up to the surface installation 15.
  • the surface installation 15 is for example a semi-submersible installation comprising a buoyant platform 30 floating on a body of water 35.
  • the body of water 35 is typically a sea, an ocean or a lake, at the surface 36 of which waves, such as swell, can form and travel.
  • the platform 30 has equipment to recover and treat fluids, such as hydrocarbons, including oil and gas. More particularly, the platform 30 has a hull 38 and a deck 40 on which may be placed, for example, cranes, storage devices, and crew quarters (not represented).
  • the surface installation 15 is kept stationary in a predetermined range of horizontal positions relative to the bottom 45 of the body of water 35, and as well, relative to the well 20. To this effect, the platform 30 is connected to the bottom of the body of water 45 with several mooring lines 50.
  • the surface installation 15 comprises at least an opening 55 extending through the hull 38 along a vertical axis Z'Z when the body of water 35 is at rest.
  • the opening 55 opens downwardly in the body of water 35. To this end, the opening 55 is delimited by a guide wall 60, part of which extends under the surface 36 of the body of water 35 up to a base 75 of the hull 38.
  • the well 20 is bored under the bottom 45 of the body of water 35 to the subterranean fluid reservoir (not represented). Fluid, such as hydrocarbons, including oil and gas, is to be pumped from the fluid reservoir to the well 20.
  • Fluid such as hydrocarbons, including oil and gas
  • the well 20 is connected to the platform 30 through at least one production tubing 80 in fluidic connection with the reservoir.
  • the production tubing 80 extends in a casing 82 of the well 20 from the reservoir up to the bottom 45 of the body of water and then to an upper end 85 located above the surface 36 of the body of water 35.
  • the upper end 85 is here positioned within the opening 55.
  • the upper end 85 is provided with a surface wellhead 90 having a stuffing box forming a structural and pressure interface between the production tubing 80 and the surface installation 15.
  • the wellhead 90 comprises a through hole 95 configured for the tight insertion of a rod 100 of the pumping device 25, which will be described below.
  • the production tubing 80 comprises an inner fluid collection and transportation volume 102, which extends below the wellhead 90 down to at least an opening located underground, near the reservoir.
  • a cylinder body is positioned at a lower part of the well 20.
  • the cylinder body defines a cylinder volume 105.
  • the cylinder body is closed at its lower end by standing valve 107. It is open at its upper end emerging in the inner fluid collection and transportation volume 102.
  • the standing valve 107 is movable between a closed position and an open position. In the open position, fluid can flow from the reservoir into a lower part 105A of the cylinder volume 105, contrary to the closed position.
  • the pumping device 25 comprises a plunger 110 movable in reciprocable translation within the cylinder 105, a buoyant body 140 floating at the surface 36 of the body of water 35 and guided by the surface installation 15 to move vertically jointly with the surface 36 of the body of water 35, and the rod 100 connecting the buoyant body 140 to the plunger 110 through the production tubing 80.
  • the plunger 110 of the pumping device 25 is engaged in the cylinder volume 105.
  • the plunger 110 is provided at an upper end 112 with through openings 115, allowing fluidic connection between an inner volume 120 of the plunger 110 and the upper part 105B of the cylinder volume 105.
  • the plunger 110 is provided at a lower end 117 with a traveling valve 125.
  • the plunger traveling valve 125 is movable between a down position and an up position. In the up position, fluid can flow from the lower part 105A of the cylinder volume 105 into the inner volume 120 or reciprocally, contrary to the down position.
  • the upper end 112 of the plunger 110 is attached to a lower end 130 of the rod 100 of the pumping device 25.
  • the rod 100 extends vertically along the vertical axis Z'Z between the lower end 130 and an upper end 135.
  • the lower end 130 of the rod 100 is engaged in the cylinder volume 105.
  • the upper end 135 of the rod 100 protrudes outside the through hole 95, above the wellhead 90.
  • the upper end 135 of the rod 100 is fixed to the upper buoyant body 140.
  • the rod 100 is thus configured to directly transmit a vertical up and down movement of the upper buoyant body 140 to the plunger 110 which then follows this up and down movement.
  • An intermediate region of the rod 100 is engaged and guided vertically by the wellhead 90.
  • the upper buoyant body 140 comprises a floating buoy 145 and an upper arch 160 carried on the floating buoy 145 to hold the rod 100.
  • the floating buoy 145 is positioned in the opening 55 and is movable in vertical translation in the opening 55. It is here vertically guided by the guide wall 60.
  • the floating buoy 145 defines a through hole 155 through which the upper end 85 of the production tubing 80 and the rod 100 are received.
  • the upper end 135 of the rod 100 is attached to the upper arch 160.
  • the floating buoy 145 floats on the body of water 35. It is moved substantially vertically, being guided by the guide wall 60, in a reciprocal movement by the movements of the body of water 35 resulting from swell.
  • a method of pumping fluid in the facility 10 is described hereafter.
  • the surface installation 15 is provided above the well 20.
  • the floating buoy 145 is positioned at the surface installation 15, for example within the opening 55 of the surface installation 15.
  • the plunger 110 attached to the lower end 130 of the rod 100 is engaged into the cylinder volume 105 of the production tubing 80.
  • the rod 100 is tightly fitted at the wellhead 90. It extends through the through hole 95 with the upper end 135 of the rod 100 being positioned above the wellhead 90.
  • the upper end 135 of the rod 100 is attached to the upper arch 160.
  • the upper buoyant body 140 moves vertically as waves and swell travel across the surface 36 of the body of water 35.
  • the movement of the floating buoy 145 is guided by vertical structural beams in the surface installation 15 and/or the floating buoy 145 is located at a side of the surface installation 15.
  • the flow line 165 leads the pumped fluid to a distant surface or onshore fluid recovery installation.
  • the floating buoy 145 is positioned above the wellhead 90.
  • a first end of each mooring line 50 is fixed to the floating buoy 145.
  • the second end of each of the mooring lines 50 is fixed on the bottom 45 of the body of water 35.
  • the mooring lines 50 are slack and thus allow a vertical movement of the floating buoy 145 under the influence of waves and/or swell.
  • the upper end 135 of the rod 100 is directly attached to the floating buoy 145.
  • the rod 100 is vertically and tightly inserted in the wellhead 90 through a stuffing box. It is able to move vertically through the wellhead 90 while preserving fluid tightness.
  • the wellhead 90 is thus a guide to guide the vertical movement of the rod 100 in the body of water 35.
  • the method of pumping fluid in the second offshore facility 10 is analogous to the one of the first offshore facility, except that the floating buoy 145 is positioned above and vertically apart from the wellhead 90.
  • the plunger 110 moves along an axis which is offset from the translation axis of the rod 100.
  • the pumping device 25 comprises a transmission mechanism (not shown) configured to transform the vertical motion of the floating buoy 145 and of the rod 100 into a movement of the plunger in the cylinder volume 105.
  • the transmission mechanism operates exclusively with a mechanical energy transmission chain. More specifically, the operation of the transmission mechanism requires no conversion of mechanical power to electrical power.
  • the transmission mechanism makes it possible to have an effective stroke length and/or stroke frequency, which is different from the wave amplitude (respectively wave frequency).
  • the plunger 110 is mounted rotative in the cylinder (e.g. like in a so-called Moineau pump).
  • the transmission mechanism converts a translation movement of the rod 100 into a rotation movement of the plunger 110.
