Definitions
- the present application relates, generally, to downhole cutting and/or perforating systems involving thermite or similar fuel as a cutting or working output medium. More specifically, the application relates to a material that selectively protects the internal surface of a fuel housing from the thermal and abrasive properties of the fuel.
- Downhole torch systems include a cylindrical housing that can house and contain fuel, such as thermite fuel pellets or other combustible fuel pellets including propellants.
- the cylindrical housing can often become adversely affected by the localized heating and flow induced during the burning of the fuel. In some situations, the fuel is held up for enough time that the wall of the cylindrical housing is completely eroded. In extreme cases, this heating of the cylindrical housing can adversely affect the performance of the torch and can reduce the overall effectiveness of the torch. In addition, this problematic heating of the cylindrical housing can affect the design of the torch, as the amount of fuel and duration of the reaction is considered and manipulated in order to avoid the catastrophic erosion condition.
- the high pressure cutting stream of the molten fuel e.g., molten fuel or plasma, combustion products
- the high pressure cutting stream of the molten fuel is significantly diminished and does not have sufficient energy to complete the cutting, perforating or other beneficial work output process. That is, some of the pressurized stream exits the breach in the housing wall, which can diminish the sufficiency of the cutting and/or perforating processes.
- a new torch system is needed that can protect the cylindrical housing of the torch from the adverse effects of the ignition and reaction of the burning fuel, and the subsequent production of combustion products (molten fuel) during operation of the torch system.
- a new torch system is needed that significantly improves the cutting and/or perforating performance of the torch system.
- the inventors of the present application have developed a material to protect the cylindrical housing from the adverse effects of the combustion products (molten fuel) during operation of the torch system, thus significantly improving the cutting and/or perforating performance of the torch system.
- the material protects the cylindrical housing from the excessive heat and erosive effects of the combustion products. The material therefore improves the efficiency, cutting and/or perforating capability and mechanical integrity of the torch system.
- the material may be of a type that decays and integrates into the combustion products. This integration into the combustion products can provide the same combustion product, or produce a second combustion product or an added layer of combustion.
- the material may include a retardant that cools the exothermic reaction of the combustion products to provide a quenching effect, which can further protect the housing from excessive heat and erosion produced by the combustion products.
- the material may be doped or altered with a tracer material that is not consumed or degraded by the combustion products and that serves as an indicator after the cutting and/or perforating process to, for example, verify the location, depth, presence or absence, and/or quality of the cut or perforation.
- a downhole torch system comprises: a cylindrical housing; a fuel load located within the cylindrical housing; and a protective material provided between the fuel load and the cylindrical housing.
- the protective material is a carbon fiber tight mesh weave.
- the protective material is formed of Kevlar, glass fiber, ceramics, carbon (e.g., graphite), polymers, epoxy, or combinations thereof.
- the protective material is a continuous layer between the fuel load and the cylindrical housing.
- the protective material can be provided on an outer surface or an outer layer of the fuel load.
- the protective material can be provided on an inner surface of the cylindrical housing.
- the fuel load can be configured to create an exothermic reaction that produces a stream of combustion products when the fuel load is ignited
- the protective material can comprise material that is configured to integrate into the stream of combustion products after the fuel load is ignited.
- the fuel load can be configured to create an exothermic reaction that produces a stream of combustion products when the fuel load is ignited
- the protective material can comprise a retardant that is configured to quench the stream of combustion products adjacent the protective material
- the fuel load can be configured to create an exothermic reaction that produces a stream of combustion products when the fuel load is ignited
- the protective material can comprise a tracer material that is not degraded by the stream of combustion products and is detectable after cutting and/or perforating by the torch assembly.
- the downhole torch system comprises a cylindrical housing, a fuel load, and a protective material.
- the steps of the method comprise providing the protective material on at least one of the cylindrical housing and the fuel load, and inserting the fuel load into the cylindrical housing.
- the method steps can further include providing the protective material on an outer surface or outer layer of the fuel load before inserting the fuel load into the cylindrical housing.
- the method steps can further include providing the protective material on an inner surface of the cylindrical housing before inserting the fuel load into the cylindrical housing.
- the protective material can be a carbon fiber tight mesh weave.
- the protective material is formed of Kevlar, glass fiber, ceramics, carbon, polymer, epoxy, or combinations thereof.
- the steps of the method can continue by configuring the fuel load to create an exothermic reaction that produces a stream of combustion products when the fuel load is ignited, and the protective material can comprise a material that can be configured to integrate into the stream of combustion products after the fuel load is ignited.
- This integration into the combustion products can provide the same combustion product, or produce a second combustion product or an added layer of combustion of the fuel load.
- the steps of the method can continue by configuring the fuel load to create an exothermic reaction that produces a stream of combustion products when the fuel load is ignited, and quenching the stream of combustion products adjacent the protective material with the protective material comprising a retardant, which is configured to quench the stream of combustion products adjacent the protective material.
- the steps of the method can continue by configuring the fuel load to create an exothermic reaction that produces a stream of combustion products when the fuel load is ignited, and the protective material can comprise a tracer material that is not degraded by the stream of combustion products and is detectable after cutting and/or perforating by the torch assembly.
- Figure 1 illustrates an isometric cut-away view of a portion of torch system 10 of the present invention.
- Figure 2 is a cross-sectional view of the torch system 10 shown in Figure 1.
- Figure 1 shows a portion of a torch system 10
- the torch system 10 includes a cylindrical housing 1, a fuel load 2 located within the cylindrical housing 1, and a protective material 3 that can be provided between the fuel load 2 and the cylindrical housing 1.
- the protective material 3 can be in the shape of a sleeve that protects the internal surface of the cylindrical housing 1 during activation and burning of the fuel load 2.
- the fuel load 2 may be thermite or other propellant fuel.
- the ignition of the thermite fuel creates a highly exothermic reaction that produces an abrasive stream of combustion products (e.g molten fuel or plasma) that forms a precise cut and/or perforation.
- the thermite fuel 2 includes a combination or a mixture of a metal and an oxidizer.
- metals can include: aluminum, magnesium, chromium, nickel, silver and/or other metals.
- the thermite fuel can bum at a temperature that may exceed 3000 degrees Celsius. The reaction occurs over a long enough period of time, such that the resultant molten fuel may be directed through a nozzle without causing the external surface to deform due to internal pressure.
- a metal oxide is created that can form, or at least partially form, a combustion product(s).
- Oxidizers that can be used to oxidize the metal can include, for example: cupric oxide, iron oxide, aluminum oxide, ammonium perchlorate, and/or other oxidizers.
- Applicant incorporates U.S. Patent No. 8,196,515, having the title of“Non-Explosive Power Source For Actuating A Subsurface Tool” by reference, in its entirety, herein.
- the ignition point of thermite can vary, depending on the specific composition of the thermite.
- the metal and the oxidizer may or may not be combined prior to ignition, which can affect the ignition point.
- the ignition point of a thermite mixture of aluminum and cupric oxide is approximately 1200 degrees Fahrenheit, while other thermite mixtures or combinations can have an ignition point as low as 900 degrees Fahrenheit.
- thermite When ignited, the thermite produces an exothermic reaction.
- the rate of the thermite reaction can occur on the order of milliseconds, while, in contrast, an explosive reaction has a rate occurring on the order of nanoseconds. While explosive reactions can create detrimental explosive shockwaves within a wellbore, use of a thermite-based power charge (non explosive or deflagration reaction) avoids such shockwaves.
- the thermite combination can include a polymer, which can be disposed in association with, or as a part of, the thermite combination.
- the polymer can be of a type that produces a gas responsive to the thermite reaction, which can slow the reaction time of the thermite such that the resultant molten fuel (combustion products) may be directed through a nozzle and onto a target.
- Usable polymers can include, without limitation, polyethylene, polypropylene, polystyrene, polyester, polyurethane, acetal, nylon, polycarbonate, vinyl, acrylin, acrylonitrile butadiene styrene, polyimide, cylic olefin copolymer, polyphenylene sulfide, polytetrafluroethylene, polyketone, polyetheretherketone, polytherlmide, polyethersulfone, polyamide imide, styrene acrylonitrile, cellulose propionate, diallyl phthalate, melamine formaldehyde, other similar polymers, or combinations thereof.
- the protective material 3 possesses properties to withstand heat and abrasion.
- the protective material 3 can be a carbon fiber tight-mesh weave selected to match the outer diameter of a fuel pellet and the inner diameter of the cylindrical housing 1.
- the protective material 3 is formed of carbon fiber, Kevlar, glass fiber, ceramics, carbon, polymer, epoxy, or combinations of these materials.
- the protective material 3 may be applied as a wrap, a sleeve, a spray-on, a paint-on, dipped, or other manufacturing techniques, complimentary to the nature of the material selected.
- the protective material 3 can be applied to the outer diameter or an outer layer of the fuel load 2, prior to inserting fuel into the cylindrical housing 1.
- the protective material 3 is applied to the inner diameter of the cylindrical housing 1, prior to inserting the fuel load 2 into the cylindrical housing 1.
- the protective material 3 may be of a type that integrates into the combustion products after the fuel load is ignited.
- the protective material 3 may decay into part of the stream of combustion products.
- the decaying protective material may provide the same combustion product, a second combustion product, or an added layer of combustion for the fuel load 2.
- Materials that would cause the protective material 3 to integrate with the combustion products may include graphite and/or carbon fiber.
- the protective material 3 is not a direct additive, for example, a polymer added to thermite, but rather enters or integrates into the combustion products as the protective material decays, a second layer of combustion products may be produced. This second layer of combustion products, formed from the decay and integration of the protective material, can affect the capacity of the fuel required to destroy, cut, perforate, and/or consume the target.
- the protective material 3 may include a retardant that cools the exothermic reaction of the combustion products.
- the retardant may provide a quenching effect that further protects the cylindrical housing 1 from excessive heat and erosion produced by the combustion products. That is, the retardant material, added to the protective material 3 or forming a part of the protective material 3, may make the reaction of the combustion products more endothermic.
- Materials for the retardant, forming at least part of the protective material 3, may include: aluminum salts, inorganic phosphates (e.g., refractory salts), anti-sputter material, slag inhibitors, barium sulfate, zinc oxide and trizinc bis- orthophosphate, and combinations thereof.
- the protective material 3 may be doped or altered with a tracer material that is not consumed or degraded by the combustion products and that serves as an indicator after the cutting and/or perforating process is performed. That is, the tracer material is detectable after the cutting and/or perforating by the torch assembly. For example, the tracer material survives the exothermic reaction of the combustion products to verify the location, depth (undercut or overcut), presence (whether the process actually perforated the target), and/or quality of the cut or perforation.
- Tracer material forming at least part of the protective material 3 may include: UV (ultraviolet) dies, physical tags, such as micro tags, fire-resistant polymer chips, which may include layers having an infrared identifiable material on one layer, ferromagnetic materials, such as iron, that are detectable with a magnet, radioactive isotope markers, such as radioactive iodine, and combinations thereof.
- the thickness of the protective material 3 can be based on the individual properties of the composition of the protective material 3. In one embodiment, the thickness of the protective material 3 can be in the range of 0.0127 cm to 0.0762 cm (0.005 inches to 0.030 inches). The thickness of the protective material 3 may be greater for larger diameter torch systems, and in circumstances in which a longer duration of protection is required due to a higher mass of the fuel load 2. In other embodiments the thickness of the protective material 3 may be up to 0.254 cm (0.100 inches) or greater.
- the protective material 3 possesses properties to withstand the large amount of heat produced and the abrasive effects of the combustion product stream. Specifically, the protective material 3 acts as a shield for the cylindrical housing 1 by: (a) increasing the thermal resistance of the cylindrical housing 1 from a combustible fuel source, resulting in a more efficient output and cutting and/or perforating process; and (b) increasing the abrasive resistance of the cylindrical housing from a stream of high temperature, high velocity abrasive particles, again resulting in a more efficient output and cutting process.
