Definitions

  • components must be arranged to survive both the running-in process and the harsh downhole environments.
  • components can experience high shear forces from contact with other tubulars or rock, dirt, sand, etc. in open portions of the borehole.
  • collision with a radially disposed tubular, borehole wall, etc. can result due to curvature or other imperfections of a borehole or string being run therein, misalignment or lack of centering of a string in a borehole, etc.
  • a system for providing temporary protection including an operative device located at an external surface of a member, and a cover externally disposed with respect to the operative device for initially protecting the operative device, the cover chemically reactive to a downhole fluid for removal of the protective cover.
  • a method of temporarily protecting an operative device including causing relative movement between a first member and a second member radially disposed therewith, the first member including an operative device located at an external surface thereof, the operative device arranged with a protective cover, exposing the protective cover to a downhole fluid, and removing the protective cover as the result of a chemical reaction between the downhole fluid and the protective cover.

  • the borehole 14 could include both cased and open portions therealong.
  • the string 12 includes a plurality of operative devices 16 a - 16 d (collectively referred to as the “operative devices 16 ”).
  • the operative devices 16 share in common that they protrude from, at least partially form, are disposed at, or are otherwise in communication with an external surface 18 of the string 12 .
  • the external surface 18 is a radially outer circumferential surface in FIG. 1 , but could alternatively be any other external surface, regardless of whether it is outwardly or inwardly facing.
  • the operative devices 16 When the operative devices 16 are located at an external surface, e.g., the external surface 18 , the operative devices are exposed to contact with radially disposed tubulars (e.g., liners, casing, etc.), borehole walls (e.g., open sections of the borehole 14 ), fluids (e.g., downhole fluids in an annulus formed between the tubular string 12 and the borehole 14 ), etc., all of which may damage or negatively impact performance.

  • borehole walls e.g., open sections of the borehole 14
  • fluids e.g., downhole fluids in an annulus formed between the tubular string 12 and the borehole 14
  • the cover 20 could, e.g., provide sufficiently high hardness, e.g., readable on the Rockwell B scale or harder, yield strength, e.g., above about 200 MPa, etc., in order to protect against abrasion, shear stresses, and/or to prevent the accumulation of materials in or about the operative device, e.g., by filling any openings or voids in, through, or about the operative devices 16 , etc.
  • the operative devices 16 could be included on any other movable or runnable tubular, or a permanently installed or immovable member that is located adjacent to a movable or runnable component.
  • the operative devices 16 even when installed in an immovable component, can be damaged by exposure to or contact with any of the aforementioned entities e.g., during run-in of the string 12 , run-in of a radially disposed tubular, relative movement of the operative device with some other member, etc.
  • the operative devices 16 could be any device operable downhole, such as sensors (distributed or otherwise), probes, fibers, wires, screens, cables, seals, packers, etc. and could be arranged for measuring (e.g., strain, acoustics vibration, pressure, temperature, etc.), filtering, sealing, isolating, communicating, etc.
  • the operative device 16 a is disposed axially with or circumferentially about the tubular string 12 and could be, for example, a mesh, wire wrap, foam, shape memory, bead pack, slotted liner, or other type of screen or filter, e.g., for enabling production of hydrocarbons while screening particulates.
  • the operative device 16 b could be, for example, optical fiber for monitoring conditions in the tubular string 12 , the operative device 16 a , etc., for enabling communication with the foregoing, etc.
  • the operative device 16 b could include portions both internal to the string 12 (e.g., where it is in communication with the external surface 18 due to openings in the device 16 a or some a screen), and external to the string 12 , as shown.
  • the operative devices 16 c and 16 d could be, for example, sensors recessed into the external surface 18 and protruding therefrom, respectively, e.g., for measuring acoustics, strain, temperature, vibration, or some other borehole condition or parameter.
  • operative devices 16 could experience damage or deterioration of performance due to their placement at an external surface.
  • the operative devices 16 could become clogged or blocked so that they can not filter, measure, monitor, sense, etc., or subjected to high stress or strain, resulting in deformation, breakage, damage, etc., either of which would disadvantageously affect performance of the devices 16 .
  • Radial or circumferential external surfaces of the operative devices 16 are each provided with a protective cover 20 .
  • the covers 20 could be, e.g., films, layers, laminae, coatings, plates, sleeves, sheets, tubes, etc. that are placed over the operative devices 16 .
  • the covers 20 are formed by winding one or more strips 20 a (e.g., helically, circumferentially, etc.) about the operative device 16 , a portion thereof, the tubular to which the device 16 is secured, etc.
  • a thin sheet 20 b is disposed over the operative device 16 . Further embodiments are described below with respect to FIG. 3 .
  • a purpose of the covers 20 is to block, cover, and generally protect the operative devices 16 , e.g., from contact with or exposure to some potentially damaging entity.
  • the covers 20 could protect delicate sensors positioned at an external surface of a string from colliding with radially adjacent tubulars or other members during run-in.
  • the covers 20 are advantageously made from a material that is chemically reactive with a downhole fluid such that after initial protection of the operative devices 16 (e.g., during run-in of a tubular string) the covers 20 can be removed for enabling the operative devices 16 to perform their designated functions.
  • “Chemically reactive” is intended to mean that the covers 20 are dissolvable, corrodible, consumable, disintegrateable, etc. or otherwise undergo a chemical reaction, e.g., dissociation, synthesis, etc., for forming new chemical products with the fluid, breaking the material down into base components (e.g., particles, ions, molecules, etc.), etc.
  • the covers 20 could be made from magnesium, aluminum, controlled electrolytic metallic materials (described in more detail below), etc. and be removed upon exposure to one or more fluids available or deliverable downhole, such as water, brine, acid, oil, etc.
  • FIG. 3 is schematically used for generically describing a variety of alternate embodiments for providing the cover 20 for protecting a generic member 22 . That is, in the embodiment of FIG. 3 , the cover 20 is formed by filling openings, pores, interstices, gaps, windows, spaces, cavities, etc. (generally, the “openings 24 ”) located between elements 26 of the member 22 with a removable material 28 at an external surface 30 of the member 22 . In one embodiment, the openings 24 are cavities, gaps, or open spaces formed about the elements 26 , which take the form of sensors or probes that are located at the external surface 30 of the member 22 . Other arrangements of sensors and other devices (e.g., resembling the operative devices 16 c or 16 d ) could be similarly protected.
  • the cover 20 is formed by filling openings, pores, interstices, gaps, windows, spaces, cavities, etc. (generally, the “openings 24 ”) located between elements 26 of the member 22 with a removable material 28 at an external surface 30 of the member
  • the member 22 is a foam filter or screen
  • the openings 24 are pores located between microspheres or cellular walls, represented by the elements 26
  • the material 28 of the cover 20 is formed by powder, particulate, grit, etc. that is smeared, rubbed, spread, impregnated, inserted, installed, or otherwise formed in or applied to the external surface 30 of the member 22 .
  • the material 28 is a controlled electrolytic metallic powder, as described in more detail below.
  • the openings in other screens, filters, etc. e.g., resembling the device 16 a ) could be similarly “pre-clogged” in this way.
  • an optical fiber is disposed within the screen and protected by the cover 20 .
  • the elements 26 represent a bundle of fibers in cross-section, and the openings 24 represent the open space between the fibers and the member 22 at the external surface 30 .
  • Other wires, cables, conduits, fibers, etc. e.g., resembling the operative device 16 b in other embodiments could be similarly protected.
  • Materials appropriate for the purpose of protective covers 20 include controlled electrolytic metallic materials.
  • the controlled electrolytic materials as described herein are lightweight, high-strength metallic materials. Examples of suitable materials and their methods of manufacture are given in United States Patent Publication No. 2011/0135953 (Xu, et al.), which Patent Publication is hereby incorporated by reference in its entirety.
  • These lightweight, high-strength and selectably and controllably removable materials include fully-dense, sintered powder compacts formed from coated powder materials that include various lightweight particle cores and core materials having various single layer and multilayer nanoscale coatings.
  • These powder compacts are made from coated metallic powders that include various electrochemically-active (e.g., having relatively higher standard oxidation potentials) lightweight, high-strength particle cores and core materials, such as electrochemically active metals, that are dispersed within a cellular nanomatrix formed from the various nanoscale metallic coating layers of metallic coating materials, and are particularly useful in borehole applications.
  • Suitable core materials include electrochemically active metals having a standard oxidation potential greater than or equal to that of Zn, including as Mg, Al, Mn or Zn or alloys or combinations thereof.
  • tertiary Mg—Al—X alloys may include, by weight, up to about 85% Mg, up to about 15% Al and up to about 5% X, where X is another material.
  • the core material may also include a rare earth element such as Sc, Y, La, Ce, Pr, Nd or Er, or a combination of rare earth elements.
  • the materials could include other metals having a standard oxidation potential less than that of Zn.
  • suitable non-metallic materials include ceramics, glasses (e.g., hollow glass microspheres), carbon, or a combination thereof.
  • the material has a substantially uniform average thickness between dispersed particles of about 50 nm to about 5000 nm.
  • the coating layers are formed from Al, Ni, W or Al 2 O 3 , or combinations thereof.
  • the coating is a multi-layer coating, for example, comprising a first Al layer, an Al 2 O 3 layer, and a second Al layer.
  • the coating may have a thickness of about 25 nm to about 2500 nm.
  • the fluids may include any number of ionic fluids or highly polar fluids, such as those that contain various chlorides. Examples include fluids comprising potassium chloride (KCl), hydrochloric acid (HCl), calcium chloride (CaCl 2 ), calcium bromide (CaBr 2 ) or zinc bromide (ZnBr 2 ).
  • KCl potassium chloride
  • HCl hydrochloric acid
  • CaCl 2 calcium chloride
  • CaBr 2 calcium bromide
  • ZnBr 2 zinc bromide
  • the particle core and coating layers of these powders may be selected to provide sintered powder compacts suitable for use as high strength engineered materials having a compressive strength and shear strength comparable to various other engineered materials, including carbon, stainless and alloy steels, but which also have a low density comparable to various polymers, elastomers, low-density porous ceramics and composite materials.
  • controlled electrolytic metallic materials are readily tailorable or conditionable for setting a rate of removal of the covers 20 . That is, the duration of desired protection can be set by altering the reactivity of the controlled electrolytic materials, e.g., changing the materials and/or proportions of materials used, such that the cover 20 is removed by the downhole fluid to enable the operative devices 16 to function properly at an appropriate time.
  • the duration of protection can be controlled instead by setting the thickness of the covers 20 with respect to a predicted rate of removal of the cover 20 in response to the downhole fluids (of course, the thickness of controlled electrolytic materials can also be set for assisting in control of the rate of removal thereof).
  • the thickness and/or reactivity of the covers 20 can be modified (e.g., by setting the thickness, by tailoring the composition of a controlled electrolytic metallic material, etc.) in order to ensure that the cover 20 is in place (and suitably robust to offer protection) for at least the one hour period of time in which it will take the string to run, and after which is chemically removed for enabling the operative device to function.
