Definitions

  • the invention is directed to injecting liquid into a packed-off perforation of a well and includes a valve which is sensitive to the pressure differential between the inside of the injection tool and the annulus between the tool and the well bore to assist in controlling the flow of the liquid.
  • This invention relates to apparatus useful to inject fluids into earth formations penetrated by a well and, more particularly, this invention relates to apparatus for use in consolidating unconsolidated sand Surrounding oil or gas or injection wells by means of injecting into the formation predeterminable amounts of consolidation liquids.
  • Sand control has heretofore been practiced by a number of methods. For exam ple. gravel or sand packing of the space between a perforated well casing and the production tubing has been done to deter the flow of sand into the production tubing. Prepacked sand control liners have also been connected to production tubing and inserted into wells and positioned adjacent a producing formation to assist in preventing sand flow up the tubing. More recently, methods have been devised to consolidate formation sand in place around the well by injecting a liquid binding material into the formation to contact the loose sand and to consolidate it when the binding material hardens.
  • the formation interval where Consolidation by this method is to be done may be a thick section made up of a number of intervals or portions having different permeabilities.
  • the consolidation liquids typically have different viscosities.
  • a casing is usually used to line a producing interval or an injection'interval. Spaced over the length of the casin g opposite the selected interval are perforations through which oil can flow into the casing from the formation or through which water can flow from the casing into the formation. Usually, the distance between perforations in the casing opposite a particular producing interval is a foot or less. In wells which penetrated a number of producing intervals a number of groups of perforations may exist spaced at appropriate intervals in the casing.
  • the sand consolidation liquids that are injected into the formation through any group of perforations will not necessarily be distributed uniformly in the formation around the well unless the injection is carefully controlled. It is a difficult problem to obtain even distribution of injected liquids through the perforations in the casing over the selected interval to be consolidated.
  • the present invention provides apparatus for sand consolidation including a central tubular member insertable into a Well and tubing means for forming a flow path between the central tubular member and the surface.
  • a plurality of packing means are provided to pack off selected portions of the well casing outside of the said central tubular member. At least one perforation of the well casing is packed off in each of the selected portions.
  • a plurality of restricted passageway means are formed through the tubular member at selected intervals to cooperate with the packing means and to provide communication between the perforations in each packed-off portion and the interior of the tubular member.
  • the restricted passageway means act in a manner similar to a critical fiow orifice in that they maintain liquid flow therethrough at a relatively constant rate at pressure above a predeterminable minimum pressure.
  • Check valve means are provided in each restricted passageway means.
  • check valve means preferably initially'close the restricted passageways to fluid flow and have resilient means to normally retain the check valve means in closed position.
  • Each check valve means is responsive to pressure increase in each of the packed-off portions of the casing and will throttle flow or even close in the event of an undesirably high pressure build-up in the packed-off portion of the casing outside the tool indicating plugging of the perforation or of the formation before damage is done to the formation.
  • FIGURE 1 is a view partially in section of a well penetrating an earth formation and illustrates apparatus assembled in accordance with the present invent'on;
  • FIGURE 2 is a sectional view showing a portion of the preferred embodiment of apparatus assembled in accordance with the present invention
  • FIGURE 3 is a front elevation taken at line 3--3 of FIGURE 2.
  • the apparatus assembled in accordance with the present invention is shown located in a well 20 adjacent the formation 21 into which the consolidated liquids are to be'injected.
  • a well casing 22 is used to line the wall of well 20.
  • Cement, or other suitable grout 23 is used to seal the annular space between the well wall and the outside of the casing 22.
  • a number of perforations 24 have been made in the casing 22 and extend through the grout 23 and into the formation 21. These perforations 24 may be made by suitable perforating means.
  • gun perforating is a suitable technique, well known in the art, for providing perforations in a well casing.
  • a tubing string 27 is connected in a fluid-tight manner to the upper end 28 of the tubular member 25 by suitable means such as adapter sub 19.
  • the tubing string 27 extends up the well and provides a flow path from the surface to the interior of the tubular member 25.
  • Suitable sources of sand consolidation liquids such as resin source 29, acetone source 30, activator source 31 and diesel source 32 are connected through pump 34 and the tubing string 27 to the tubular member 25.
  • the tubular member 25 is provided with a plurality of pack-E means 33 which pack off portions of the annular space between the well casing 22 and the outside wall of the tubular member at a plurality spaced apart locations. It is contemplated that the pack-01f means of the present invention will be arranged to pack off one or more of 'a plurality of perforations 25. Thus a plurality of annular chambers are formed to each provide communication from the interior of the tubular member with one or more of the perforations.
  • the packing means 33 are only schematically represented in FIGURE 1 and they may be of any suitable construction and may be activated mechanically or hydraulically or by any other suitable means well known in the art.
  • suitable hydraulic packers include the hydrostatic packer illustrated on page 516 of the 26th (1964-65) Revision of the Composite Catalog of Oil Field'Equipment and Service.
  • Another example of a suitable hydraulically set packer is illustrated on page 866 of the 29th (1962-63) Revision of the Composite Catalog.
  • Means forming restricted passageways having check valve :meansformed therein are provided to allow communication between the tubular member 25 and each of I the packed-off perforations. These means are generally indicated by the numeral 35.
  • the means forming a restricted passagewayand the check valve means are housed together in a common removable housing member 36. With reference to FIGURES 2 and 3 these means will be described in greater detail.
  • a housing member 36 is, provided to contain the restricted passageway and the check valve means.
  • the housing member 36 is removably connected in the tubular member 25 as by mating threads 60 and 61.
  • a suitable restricted passageway means may include flow paths 40 and 42 and an orifice insert 41 which has a restricted opening 46.
  • a check valve seat 43 having an opening 44 therethrough'completes the passageway.
  • the flow paths and inserts are providedwith easy access for cleaning purposes.
  • the inserts 41 and 43 are removable and one end of flow path 42 is closed by means of removable plug45.
  • the inserts, housing members and plugs are provided with suitable grooves 65 to allow easy removal and insertion. The grooves 65 are cut only deep enough into the members to permit engagement by a key.
  • a check valve means is provided is the restricted passageway.
  • ja check valve stem is normally urged into valve seat 43 by means of a suitably arranged spring 51 to close the passageway.
  • the upper end 52 of valve stem 50 is formed in a piston like manner and fits in fluid-tight slideable relationship in chamber 54.
  • a back plate 55 acts to Iseat spring 51.
  • An opening 56 in the back plate allows pressure on the outside of the apparatus to act on the piston end of the valve stem.
  • the piston member is also &
  • the restricted passageways are used to assist in accomplishing equal or nearly equal distribution of the consolidation liquids to the formation.
  • a compressible fluid is pumped through an orifice at a constant upstream pressure there is a pressure diflerence across the orifice at which maximum flow occurs and even if the downstream pressure decreases so that the pressure difference becomes greater than the critical pressure diflerence no more flow occurs.
  • the consolidation liquids will react in somewhat a similar manner when flowing through the restricted passageway.
  • the passageways are sized so that only a predetermined amount of flow can take place through each passageway after a certain pressure differential bewteen the inside and outside of the tubular member is reached.
  • the check valve means throttles flow and eventually shuts off flow through the restricted passageway.
  • the liquid flowing through the plurality of passageway is thus flow-regulated and even though one of the perforations might have the capacity to take the consolidation liquids at a much higher rate than the perforations in another packed-otl portion, that perforation will receive the predetermined amount of consolidation liquid since each perforation is packed off and the flow to each packed-off portion is regulated.
  • This is true so long as the perforation taking liquid at the slowest rate is capable of taking the liquid at a rate faster than the rate of the liquid flow through the restricted passageway. In most formations this will be the case. However if for some reason, such as a very tight portion of a formation or plugging of a perforation, the fluid is not taken by the formation at at least this minimum rate pressure build-up in the annulus can occur.
  • the increased pressure can result in fracture of the formation. If pressure build-up reaches an undesirably high level the check valve means of the present invention reacts as heretofore described to close the particular passageway to the flow of liquid thus preventing damage to the formation. When the pressure has dropped to a safe level the check valve opens and flow resumes. As is evident the strength of the check valve spring can be changed to vary the differential pressure required to close the check valve. It is contemplated that good engineering practice can determine the desirable diiferential pressure for any given operation knowing the fracture pressure of the formation, the strength of the tool and other factors.
