Definitions

  • the invention pertains to a fluid injection apparatus and method with controlled volume displacement for use in the treatment of one or more zones or sections within a subterranean well.
  • a “treatment fluid” such as an acid, a polymer, a “sporting” fluid, corrosion or scale inhibitor, or other similar and known chemical, such as cement, plastic, epoxy, gel, or the like.
  • a "bailer” which is introduced into the well on a wireline, or the like.
  • the bailer contains a specific volume and is activatable due to density differential of the treatment fluid relative to the natural fluids in the wellbore at the time and location of treatment.
  • the present invention addresses the problems associated with such prior art apparatuses and methods.
  • Fig. 1 is an elevational cross-sectional view of the apparatus of the present invention introduced to a predeterminable location within a subterranean well and prior to activation.
  • Fig. 2 is a view similar to that of Fig. 1 taken subsequent to activation of the apparatus.
  • Fig. 3 is a view of an alternative preferred apparatus in the position as shown in Fig. 1.
  • Fig. 4 is a view of the apparatus of Fig. 3 subsequent to activation.
  • Fig. 5 is a longitudinal cross sectional view of another alternative embodiment of the present invention incorporating plural chambers and piston means and shown in the position prior to activation.
  • Fig. 6 is a view of the apparatus of Fig. 5 subsequent to activation of one of the piston means in one of the chamber elements.
  • Fig. 7 is a view of the device shown in Figs. 5 and 6 subsequent to activation of a plurality of piston elements within their respective chamber means for discharge of a plurality of treatment fluids, either concurrently or in tandem.
  • Fig. 8 is an illustration of yet another embodiment of the present invention wherein the chamber means is provided by the interior walls of the conduit introduced into the subterranean well.
  • the present invention provides a fluid injection apparatus with controlled volume displacement for use in ejecting a treatment fluid in a subterranean well.
  • the device is carriable into the well on a conduit, such as continuous coil tubing, a workover string, or by wireline.
  • the conduit will be a workover string or continuous coiled tubing or other conduit having a fluid passageway interiorally thereof.
  • the apparatus of the present invention may comprise a cylindrical housing having an interior fluid chamber for receipt of the treatment fluid. Means, such as threads, are provided at one end of the housing for securing the apparatus to the conduit.
  • Piston means are carried within the chamber for isolating fluid within the chamber from the passageway and are movable from a first position whereby the chamber is in expanded condition retaining fluid therein to a second position whereby the chamber is in a contracted condition and the treatment fluid is ejected from the chamber into the well.
  • the apparatus of the present invention may be carried into a well on a conduit other than one having an interior fluid receiving passageway, such as by wire or electric line.
  • conduit other than one having an interior fluid receiving passageway, such as by wire or electric line.
  • means must be incorporated therein in conventional fashion for providing application of pressure to one side of the piston means for moving same to contract the chamber and eject the treatment fluid.
  • the apparatus may be provided in a form whereby it is not an independent tool or component specifically carried by the conduit and is provided as an integral component part of the conduit. Moreover, the apparatus may be provided in a form in which tandem or sequential ejection of separate treatment fluids is accomplished by utilizing two or more "stacked" chambers and pistons either provided in parallel, horizontal or vertical alignment.
  • the present invention provides positive controlled volume displacement of a treatment fluid and can accommodate pumping volumes as low as 3 gallons to 2 gallons of fluid per minute. This permits specialized, controlled pumping operations of expensive treating chemicals, such as polymers, chelants, monomers, cross-linking agents, reaction catalysts, chain stoppers, acids, buffering agents and the like. This controlled displacement insures that treating fluids are not over displaced and are located at the proper treatment interval within the well.
  • the present invention provides a diaphragm or similar component, housed within the floating piston element, which is rupturable or otherwise openable to a passageway within the conduit for circulation in the treatment chamber and the fluids in the well, in one of many known fashions.
  • Fig. 1 there is shown the fluid injection apparatus 10 of the present invention secured at threads 11 to a conduit CT having a series of radially disposed pressure relief ports PRD immediate the lowermost end thereof that are normally covered by an interior sliding sleeve mechanism (not shown).
  • the conduit CT may be continuous coiled tubing, conventional workover or drillstring, or the like.
  • the conduit CT has a fluid passageway FP therein for introduction of a pressureable fluid for activating the apparatus 10 as described below.
  • the apparatus 10 comprises a cylindrical housing 12 secured at its uppermost end to the conduit CT by the threads 11.
  • the cylindrical housing 12 has an interior smooth wall 12A' for receipt of a floating piston 13 having a upper face 13A in communication with the fluid passageway FP.
  • a lower face 13B defines the uppermost, or one, end of a fluid chamber 20.
  • An O-ring seal 14 is contained within a circumferentially defined grooveway 14A around the outermost circumference of the floating piston 13 for sealing movements along the smooth wall 12A of the interior of the cylindrical housing 12.
  • the cylindrical housing 12 of the apparatus 10 also provides a piston seat sub 12A having an upwardly facing-inwardly extending shoulder abutment 12B for terminating the lower travel of the floating piston 13, as described, below.
  • a port 12C is defined within the piston seat sub 12A to permit filling of the fluid chamber 20 with the desired treatment fluid prior to introduction of the fluid apparatus 10 to the wellbore WB.
  • the port 12C is sealed by introduction of plug 12D in securement within the plug port 12C subsequent to the filling of the fluid chamber 20 at the top of the well.
  • the port 12C and plug 12D may, of course, be deleted and the apparatus 10 filed at the top of the well before introduction into the well.
  • a stinger element 12E is secured by threads 12E 1 to the lowermost end of the piston seat sub 12A.
  • the stinger 12E contains a blowout plug 15 which is secured in place to block the lowermost end of the fluid injection apparatus 10 by means of a series of radially extending shear pins 13, 14. Fluid communication between the exterior of blowout plug 15 and the interior of the stinger 12E is prevented by means of provision of an O-ring seal element 16 housed within a groove 16A.
  • the apparatus 10 has been run into the wellbore WB for desired treatment of fractures F through perforations P in casing C.
  • the floating piston 13 may contain an opening 13C therethrough as well as a rupturable diaphragm member 13D at the inwardly extending face 13B of the floating piston 13.
  • the opening 13C is provided within the floating piston 13 to permit fluid pressure in the fluid within the fluid passageway FP of the conduit CT to be applied to the diaphragm 13D to rupture same subsequent to activation of the apparatus 10 as described below, to permit subsequent introduction into the wellbore WB of the fluid within the fluid passageway FP for subsequent treatment of the well through the perforations P, or any other desired, and known, purpose.
  • a plurality of tandem, parallel floating pistons 13 may be provided in a fluid injection apparatus 10 which contains companion fluid chambers 20 and 20 1 separated by a chamber isolator 17.
  • the shear pins 113 and 113 1 may provided with separate shear load or strength characteristics such that one of the blow out plugs 15 is ejected out the lowermost end of the apparatus 10 prior to breaking or shearing of the other pin 13 1 to subsequently eject the blowout plug 15 1 from the lowermost end of the fluid chamber 20 1 . They may also, of course, have the same shear load resulting in simultaneous breaking.
  • the rupture rating of the disk 13D and 13D 1 are varied such that one of the passageways 13C is open before the other passageway 13C 1 is opened for sequential introduction of the fluid within the fluid passageway FP through the pistons 13, 13 1 , the chambers 20, 20 1 thence exteriorly of the apparatus 10 through the respective lower ends. Accordingly, the fluid within one of the chambers 20, is caused to be introduced into the wellbore WB prior to activation of the other of the chambers 20 1 and the second, parallel piston 13 1 , as shown in Fig. 6.
  • Such embodiment of the present invention would have application in the event that a polymer composition is desired to be prepared in-situ by means of monomer "A” being placed within fluid chamber 20 and monomer “B” being placed in fluid chamber 20 1 with requirement that monomer “A” be deposited within wellbore WB for a given time prior to introduction of monomer "B” in chamber 20 1 into the wellbore WB at a subsequent, or delayed time.
  • FIG. 8 there is shown an alternative embodiment of the present invention in which the fluid injection apparatus 10 actually is a part of the conduit CT and is not provided at the lowermost end of the conduit CT by threads 11 engaging the apparatus 10 to the lowermost end of the conduit CT.
  • the apparatus 10 When it is desired to treat the wellbore WB and/or the fractures F through the perforations P in the casing C, the apparatus 10 is secured by threads 11 to the lowermost end of the conduit CT. Thereafter, the treatment fluid is introduced into the fluid chamber 20 by means of the port 12C and the floating piston 13 moves to the position as shown in Fig. 1. The port 12C is plugged by introduction of the plug 12D therethrough. Now, the apparatus 10, is run into the wellbore WB on the lowermost end of the conduit CT until such time as the approximate lowermost end of the apparatus 10 is parallel to the perforations P. Now, pressure is applied to the fluid within the conduit CT and the fluid passageway FP to be applied the upper face of the piston 13A and compressing the fluid within the fluid chamber 20.
  • the piston 13 When the embodiment of the invention is utilized as shown in Figs. 3 and 4, the piston 13 is pumped to the position shown in Fig. 4 to positively discharge all of the fluid from within the fluid chamber 20. Thereafter, fluid pressure within the conduit CT and the fluid passageway FP is continued to be increased until such time as the diaphragm 13D is ruptured. Upon rupture of the diaphragm 13D, fluid within the conduit CT may pass through the passageway or opening 13C within the interior of the floating piston 13, thence through the outer open end of the apparatus 10 for introduction into the wellbore WB, for spotting, circulation, and/or recirculation, as the occasion merits.
  • the embodiment of the apparatus 10 shown in Fig. 8 provides for the interior of the conduit CT to be the fluid chamber 20 which is blocked or isolated by means of one floating piston 13 bridging the fluid chamber 20 and the fluid passageway FP in the conduit CT thereabove.
  • the apparatus is activated and operated as for the embodiment as shown in Figs. 3 and 4.
