Definitions

  • the present invention relates to subterranean cementing operations, and more particularly, to cement compositions comprising elastic particles and having improved mechanical properties, and methods of using such compositions in subterranean cementing operations.
  • Hydraulic cement compositions are commonly utilized in subterranean operations, particularly subterranean well completion and remedial operations.
  • hydraulic cement compositions are used in primary cementing operations whereby pipe strings such as casings and liners are cemented in well bores.
  • hydraulic cement compositions are pumped into the annular space between the walls of a well bore and the exterior surface of the pipe string disposed therein.
  • the cement composition is permitted to set in the annular space, thereby forming an annular sheath of hardened substantially impermeable cement therein that substantially supports and positions the pipe string in the well bore and bonds the exterior surfaces of the pipe string to the walls of the well bore.
  • Hydraulic cement compositions also are used in remedial cementing operations such as plugging highly permeable zones or fractures in well bores, plugging cracks and holes in pipe strings, and the like. Subterranean formations transversed by well bores are often weak and extensively fractured.
  • the formation may be unable to withstand the hydrostatic head pressure normally associated with cement being pumped in the formation.
  • the hydrostatic pressure may be sufficient to force cement into the extensive fractures of the formation, which may result in a significant loss of cement into the formation during cementing operations.
  • This problem of losing fluid into a subterranean formation due to the hydrostatic pressure exerted by the fluid is commonly referred to as "lost circulation.”
  • This loss of cement composition is problematic because less cement composition will remain in the annular space to form the protective sheath that bonds the pipe string to the walls of the well bore. Accordingly, the loss of cement composition is of great concern. Resolution of this concern may call for reducing the density of the cement, inter alia, to reduce the hydrostatic pressure applied to the formation.
  • a traditional means of reducing the density of the cement composition has been to increase the cement composition's water content, because, generally speaking, the higher the water content, the less dense the cement composition.
  • this method may be problematic because the resultant cement composition often requires extensive cure time and lacks the desired strength and mechanical properties.
  • lightweight spherical or substantially spherical particulates have been added to such compositions.
  • Some lightweight spherical or substantially spherical particulates include hollow spheres, which are typically cenospheres, glass hollow spheres, or ceramic hollow spheres.
  • Cenospheres are hollow spheres primarily made from silica (SiO 2 ) and/or alumina (Al O ), and are filled with gas. These are a naturally occurring by-product of the burning process of a coal-fired power plant.
  • Conventional glass hollow spheres and ceramic hollow spheres reduce the density of the cement composition such that less water is required to form the cement composition. As a result, the curing time of the cement composition is reduced.
  • conventional hollow spheres are by nature brittle and fragile, and thus the cement containing the spheres often cannot endure the repeated detrimental stresses that the set cement may encounter in a subterranean well bore during the life of a well.
  • cement failure may also be caused by the phenomenon of hydration volume reduction of the cement composition during the curing process.
  • Hydraulic cement compositions typically demonstrate a decrease in volume as the cement composition develops compressive strength and sets. This shrinkage may adversely impact the set cement through the formation of cracks and other imperfections that may occur in the set cement. For instance, any cracks may provide a path for subterranean fluids to penetrate and weaken the cement sheath, and ultimately attack the casing of the well bore, potentially causing the casing to fail during the life of the well.
  • Premature casing failure can result in, inter alia, costly repairs, lost production, and complete loss of the well under certain circumstances.
  • the problem of hydration volume reduction has been addressed through the use of particulate expanding additives.
  • these expanding additives When added to the cement slurry, these expanding additives react with the slurry to produce a gas. The volume of the slurry is increased by the generation of this gas, which compensates for hydration volume reduction.
  • the use of expanding additives to compensate for hydration volume reduction may necessitate testing to optimize the cement composition.
  • the particulate nature of these expanding additives may necessitate the incorporation of additional procedures.
  • Failure to properly resolve this dilemma may lead to the increased probability of failure of the set cement in the well bore, which may result in, inter alia, radial or circumferential cracking of the set cement as well as a breakdown of the bonds between the set cement and the pipe or between the cement sheath and the surrounding subterranean formation.
  • Such failures can result in at least lost production, environmental pollution, hazardous rig operations, and/or hazardous production operations.
  • a common undesirable result is the presence of pressure at the well head in the form of trapped gas between casing strings.
  • a cement composition should develop high bond strength after setting, and also should have sufficient mechanical properties including elasticity, flexibility, compressibility, and ductility to resist loss of pipe or formation bonding, cracking, and/or shattering as a result of all of the stressful conditions that may plague the well, including impacts and/or shocks generated by drilling and other well operations.
  • the present invention relates to subterranean cementing operations, and more particularly, to cement compositions comprising elastic particles and having improved mechanical properties, and methods of using such compositions in subterranean cementing operations.
  • An example of a method of the present invention is a method of avoiding the loss of circulation of a cement composition in a subterranean formation, comprising the steps of: providing a cement composition comprising a base fluid, a hydraulic cement, and a portion of elastic particles; placing the cement composition in a well bore in a subterranean formation; permitting a portion of the cement composition to enter openings in a region of the subterranean formation in fluid communication with the well bore; and permitting the portion of the cement composition to seal the openings off from the well bore.
  • Another example of a method of the present invention is a method of improving the ability of a cement composition to resist the loss of circulation, comprising the step of adding to the cement composition a portion of elastic particles.
  • the present invention relates to subterranean cementing operations, and more particularly, to cement compositions comprising elastic particles and having improved mechanical properties, and methods of using such compositions in subterranean cementing operations. While the methods of the present invention are useful in a variety of subterranean applications, they are particularly useful in well completion and remedial operations, including primary cementing, e.g., cementing casings and liners in well bores, including those in multi-lateral subterranean wells.
  • the cement compositions useful with the methods of the present invention generally comprise a hydraulic cement, a portion of elastic particles, and a base fluid.

  • the base fluid may be aqueous-based, nonaqueous-based, or a mixture thereof.
  • the base fluid may comprise fresh water, salt water (e.g., water containing one or more salts dissolved therein), brine (e.g., saturated salt water), or seawater.
  • salt water e.g., water containing one or more salts dissolved therein
  • brine e.g., saturated salt water
  • seawater Generally, the water can be from any source provided that it does not contain an excess of compounds that may adversely affect other components in the cement composition.
  • the base fluid is nonaqueous-based, the base fluid may comprise any number of organic liquids.
  • suitable organic liquids include, but are not limited to, mineral oils, synthetic oils, esters, and the like.
  • any organic liquid in which a water solution of salts can be emulsified is suitable for use as a base fluid in the cement compositions used with the present invention.
  • the base fluid may be present in an amount sufficient to form a pumpable slurry. More particularly, in certain embodiments the base fluid is present in the cement compositions in an amount in the range of from about 25% to about 150% by weight of cement ("bwoc"). In certain preferred embodiments, the base fluid is present in the cement compositions in the range of from about 30% to about 75% bwoc.
  • the cement compositions useful with the methods of the present invention further comprise a portion of elastic particles.
  • the term "elastic” will be understood to mean the tendency for a particle to deform or compress under an applied force, and then re-expand as the force is removed, without substantial adverse effect to the structure of the particle.
  • Any elastic particle that is compatible with a cement (e.g., that is relatively chemically stable over time upon incorporation into the cement) and that is substantially impermeable to the fluids typically encountered during cementing operations may be suitable for use with the cement compositions used in the present invention.
  • the elastic particles have a specific gravity in the range of at least about 0.05. In certain preferred embodiments, the elastic particles have a specific gravity in the range of from about 0.3 to about 0.99.
  • the elastic particles will also have an isothermal compressibility factor.
  • isothermal compressibility factor will be understood to mean a particle's change in volume with pressure per unit volume of the particle while temperature is held constant. Any elastic particle having an isothermal compressibility factor in the range of from about 1.5xl0 "3 (1/psi) to about 1.5xl0 “9 (1/psi) may be suitable for use with the present invention.
  • the elastic particles are present in the cement compositions useful with the present invention in an amount sufficient to provide a cement composition having a desired density and desired mechanical properties such as, inter alia, a desired Young's modulus and tensile strength.
  • the elastic particles may be present in the cement compositions in an amount in the range of from about 1% to about 200% bwoc. In certain exemplary embodiments, the elastic particles are present in the cement composition in an amount in the range of from about 5% to about 100% bwoc. In certain exemplary embodiments, the elastic particles are present in the cement composition in an amount in the range of from about 5% to about 10% bwoc. In certain embodiments, the elastic particles will further comprise an internal fluid. Where the elastic particles comprise an internal fluid, the internal fluid may become incorporated within the elastic particles, so that the elastic particle forms a boundary around the fluid, by any suitable means. For example, the internal fluid may be injected into the elastic particle.
  • the internal fluid may become incorporated within the elastic particle as a natural consequence of the process of manufacturing the elastic particle.
  • One of ordinary skill in the art with the benefit of this disclosure will recognize an appropriate means by which the internal fluid may become incorporated within the elastic particle.
  • the incorporation of an internal fluid within the elastic particles permits adjustment of the density of the elastic particles by pre-expanding them to a desired density.
  • the elastic particles comprising the internal fluid may be thermally pre-expanded.
  • the elastic particles may be pre-expanded up to about 40 times their original volume before being added to the cement composition.

Other fluids may also be suitable for use as internal fluids, and one of ordinary skill in the art with the benefit of this disclosure will be able to identify an appropriate internal fluid for a particular application.
  • the elastic particles may be configured in any shape.
  • the elastic particles may generally be of any size sufficient to permit the particle to behave elastically.
  • the elastic particles are spherical or substantially spherical in shape.
  • the elastic particles have a substantially spherical shape and a diameter of at least 1 micrometer when measured at about 25°C and about atmospheric pressure.
  • the elastic particles have a substantially spherical shape and a diameter of about 3,000 micrometers when measured at about 25°C and about atmospheric pressure.
  • the elastic particles have a substantially spherical shape and a diameter in the range of from about 2 to about 150 micrometers when measured at about 25°C and about atmospheric pressure.
  • An example of a suitable elastic particle comprises a polymer that, over the range of temperatures and pressures encountered in the well bore, changes volume by expansion and contraction, and consequently may impart desired mechanical properties to the cement composition.
  • Suitable polymers may include those that possess sufficient rubbery and elastic characteristics to allow the elastic particles to respond to changes in volume of the fluid within the elastic particles at temperatures and pressures commonly encountered in the well bore.
  • the elastic particles comprise a copolymer of styrene and divinylbenzene.
  • Another example of suitable elastic particles comprises either a copolymer of styrene and acrylonitrile or a terpolymer of styrene, acrylonitrile, and vinylidene chloride, and a fluid, such as isobutane or the like.
  • Such particles are commercially available under the trade name "EXPANCEL” from Akzo Nobel, Inc., of Duluth, Georgia.
  • EXPANCEL elastic particles with different polymer-softening temperatures, allowing for expansion and contraction at different temperature ranges, are available. Depending on the conditions of the subterranean well bore in which the elastic particles may be placed, a particular grade of EXPANCEL elastic particles may be suitable.
  • the substantial impermeability of the elastic particles to the fluids typically encountered during cementing operations may also be achieved by appropriately encapsulating or coating a prefabricated elastic particle with appropriate materials.
  • an elastic particle intended for use, inter alia, in a nonaqueous-based cement composition may be coated or encapsulated with a hydrophihc material.
  • An elastic particle intended for use in an aqueous- based cement composition may be coated or encapsulated with a hydrophobic material.
  • suitable hydrophobic materials include, inter alia, silanes, silicone polymers, latexes, and the like.
  • suitable hydrophihc materials include, inter alia, ethylene oxide, propylene oxide, acrylic acid, 2-acrylamido-2-methylpropane sulfonic acid, aminoalkoxysilanes, and the like.
  • certain exemplary embodiments of the elastic particles may be expanded before mixing with the cement by heating the elastic particles, thereby increasing the pressure of the fluid therein.
  • the benefit from expanding the elastic particle may be weighed against the cost in terms of manpower and energy to achieve such expansion.
  • expansion by heating may be suitable for certain embodiments of the elastic particles (e.g., the EXPANCEL particles), other embodiments of the elastic particles may be susceptible to thermal degradation from such heating.
  • the expansion of the elastic particles generally may be measured by a corresponding reduction in the specific gravity of the expanded elastic particle.
  • the elastic particles are capable of expanding up to about 40 times their original volume, e.g., the volume at about 25°C and about atmospheric pressure.
  • the temperature to which the elastic particles are heated depends on factors such as the chemical composition of the particle. For example, the glass transition temperature of the polymer used to make the particles could affect the temperature to which the particles are heated.
  • the temperature to which the elastic particles are heated also depends on other factors including, but not limited to, the desired density of the cement composition.
  • the addition of the elastic particles to a cement composition may reduce the density of the cement composition.
  • the presence of the elastic particles in the cement compositions used in the present invention provides improved elasticity, resiliency, and ductility to the ensuing hardened cement sheath, and protects it from experiencing brittle failure during the life of the well. The elastic particle contracts, to some extent, under pressure, and subsequently expands when the pressure is removed.
  • the elastic particles of the present invention can withstand pressures in excess of about 21,000 psi without crushing, and may rebound upon release of the pressure to about their original dimensions. Accordingly, the elastic particles provide a mechanism for the cement compositions used in the present invention to absorb stress imposed by the temperature and pressure conditions encountered in a subterranean formation. Among other benefits, the elastic particles also enable the cement composition to endure the reduction in hydration volume ("shrinkage") and associated changes that may occur while the cement sets in the subterranean formation. Among other benefits, the elastic particles in the cement compositions used in the present invention may reduce the problem of loss of circulation of the cement composition into the fractures of the subterranean formation, because they permit the density of the cement compositions to vary.
  • the cement composition may have a lower density at shallower depths, and subsequently have a higher density at greater depths, due to factors such as the compressibility of the elastic particles. This may permit the cement compositions to have a sufficiently low density at shallow depths to avoid lost circulation at such low depths, yet also have a sufficiently high density at greater depths to prevent fluid influx from the subterranean formation surrounding the well bore. If the zones within the subterranean formation where circulation may potentially be lost are at a shallow depth, then the cement compositions may be able to prevent or minimize lost circulation, because the cement composition will have a sufficiently low density at such shallow depth to avoid fracturing the subterranean formation.
  • This lower density reduces the hydrostatic pressure exerted by the column of cement composition at such shallow depth that might otherwise cause the cement composition to enter the fractures within the lost circulation zone.
  • the presence of the elastic particles in the cement compositions may minimize such loss of the cement composition due to factors such as the expansion of the elastic particles as they enter lower pressure zones within the formation, so as to seal off such lower pressure zones from the well bore, which will prevent further loss of circulation.
  • Lower pressures may exist within the lost circulation zones in the formation for reasons including the fact that such zones may provide a broad flow area, as well as because frictional losses may occur as the cement composition travels through such zones within the formation.
  • the cement compositions used in the present invention may comprise fibers.
  • the fibers are, in certain exemplary embodiments, high tensile modulus carbon fibers that have a high tensile strength.
  • the tensile modulus of the fibers may exceed 180 GPa, and the tensile strength of the fibers may exceed 3000 MPa.

Abstract

La présente invention concerne des opérations de cimentation sous-terraine et, plus particulièrement, des compositions de ciment contenant des particules élastiques et ayant des propriétés mécaniques améliorées, et des procédés d'utilisation de telles compositions dans des opérations de cimentation sous-terraine. Un exemple du procédé selon l'invention consiste à prendre une composition de ciment contenant un fluide de base, un ciment hydraulique et une fraction de particules élastiques; à placer la composition de ciment dans un puits de forage dans une formation sous-terraine; à amener une partie de la composition de ciment à pénétrer dans les trous d'une zone de la formation sous-terraine en communication fluidique avec le puits de forage; et à permettre à cette partie de la composition de ciment de sceller les trous de sortie du puits de forage. Un autre exemple du procédé de la présente invention comprend l'étape permettant d'ajouter une fraction de particules élastiques à une composition de ciment.
