Definitions
- This invention relates to oil and gas exploration and more particularly, to joint connections for radially expandable tubular members used in the oil and gas industry.
- strings of tubulars of different diameters are typically placed in a wellbore for purposes that include, for example, stabilizing a formation or protecting a borehole against elevated wellbore pressures.
- One of the newest and most demanding technologies involving these strings of tubulars used in well drilling today is "expandable technology” (See, for example, SPE paper 56500, “Expandable Tubular Solutions,” by A. Filippov, at al., 1999) in which tubular member may be plastically radially expanded to diameters larger than the original diameters in the wellbore, thereby minimizing the reduction in internal diameter of the ordinary telescopic well design.
- FIG. 1 generally shows a radially-expandable threaded tubular assembly connection as known in the prior art.
- the tubular assembly 1 generally comprises a radially- expandable male threaded element 2 having external male threading 3 and a free end 4, a radially expandable female threaded element 5 having internal female threading 6 and a free end 7.
- the male and female threaded elements 2, 5 may be, for example, radially-expandable tubing, casing, or other solid expandable tubulars.
- the male threaded element 2 is commonly referred to as a "pin” or “pin member” and the female threaded element 5 is commonly referred to as a “box” or “box member.”
- the pin 2 and box S are coupled together by threading the pin 2 into the box 5 and applying a desired, and usually predetermined, amount of torque to form the tubular assembly 1, often referred to as "joint,” or “threaded connection.”
- a box member may also be formed as a coupling that provides a tubular assembly having two tubulars with pin members that are joined by a coupling having two box member elements.
- the tubulars may have pin members at both ends that are joined with adjacent tubulars with the box members in the form of a coupling.
- a tubular connection includes a box member at the end of a tubular or a coupling having an internal thread, an outer sleeve disposed about the box member and a bonding layer bonding the outer sleeve to the box member.
- the present invention is particularly useful, but not limited to, radially-expandable tubular connections used in the oil and gas drilling and production industries.
- Particular embodiments of the present invention are further useful for preventing a crack from propagating from the protective sleeve into the box member, especially when the tubular connection is undergoing radial expansion.
- the bonding material that forms the bonding layer between the box member and the outer sleeve may be of any suitable bonding material such as, for example, an adhesive, a retaining compound, an anaerobic cure adhesive, solder, brazing metal, weld material or combinations thereof.
- the bonding layer is characterized as having a bonding strength that does not exceed a threshold crack-propagating bonding strength.
- the threshold crack-propagating bonding strength is typically equal to about one-fifth of the cohesive strength of the box member.
- the thickness of the outer sleeve is greater than about 0.02 inches and preferably, is between about 0.04 and about 0.1 inches.
- the outer sleeve may be of any suitable pliable material including, for example, metals, ductile steel, stainless steel, steel alloys, copper, brass, synthetic thermoplastic, fiber composite material or combinations thereof.
- a method for protecting a box member of a radially-expandable tubular connection includes the steps of applying a bonding material to form a bonding layer to an outer surface of the box member, an inner surface of an outer protective sleeve, or combinations thereof; disposing the outer sleeve about the box member; and bonding the outer sleeve to the box member with the bonding material.
- the bonding material may be any suitable bonding material such as, for example, an adhesive, a retaining compound, an anaerobic cure adhesive, solder, brazing metal, weld material or combinations thereof.
- the bonding layer has a bonding strength that is less than a threshold crack-propagating bonding strength.
- FIG. 1 is a perspective view, partially in section, of a radially-expandable threaded tubular assembly connection as known in the prior art.
- FIGS. 2A-2B are fragmentary, radial cross-sectional views of a radially- expandable tubular connection.
- FIG. 2C is a fragmentary, radial cross-sectional view of a radially- expandable tubular connection having a blunted crack in accordance with the present invention.
- the present invention provides tubular connections and methods for making tubular connections that are useful for joining tubular members together to form a pipe string. These tubular connections and methods are useful in the oil and gas drilling and production industries but the invention is not thereby so limited.
- the present invention is particularly useful for joining together radially-expandable tubular members used in the oil and gas drilling and production industries.
- a particular embodiment of a tubular connection of the present invention includes a box member having an internal thread for joining with a pin member of a tubular member.
- the wall thickness of the box member is significantly reduced from the overall thickness of the tubular member because the box member is typically both internally tapered and threaded as shown in FIG. 1.
- the box member may be protected with a protective outer sleeve that is disposed about the box member.
- the outer sleeve protects the thin- walled portion of the box member from damage such as, for example, scratches, sharp dents, cuts, nicks and scuffing that can occur during handling, transportation or lowering of the joined tubular members into the well.
- the tubular connection further includes a bonding layer to bond the outer sleeve to the box member.
- the bonding layer preferably comprises any suitable material that is characterized as having a shear strength high enough to prevent the outer sleeve from sliding along the joined tubular members or from rotating about the box from forces that may be typically applied to the sleeve.
- Such forces include those forces applied to the outer sleeve during, for example, transportation, handling or lowering the joined tubular members into the well. These forces are typically shear forces that tend to displace the sleeve along the length of the joined tubular members or tend to cause the sleeve to rotate about the box member.
- the bonding strength is the strength the adhesive or bonding material may exert against (or apply to withstand) decoupling forces in the direction perpendicular to the bonded surfaces (ASTM D897-01 ) .
- Suitable materials useful for bonding the outer sleeve to the box member include, for example, adhesives, retaining compounds, solders, brazing metals, welding materials or combinations thereof.
- Adhesives having high shear strength and relatively low adhesive strength are generally known as retaining compounds.
- Retaining compounds are often used to assemble cylindrical press and slip-fit parts and to fill the inner space between these cylindrical components.
- TORQUE 20RC from Adhesive Systems, Inc., is a retaining compound useful for joining fitted cylindrical parts and provides shear strength of about 4000 psi on steel and can fill diametrical gap distances of up to about 0.015 inches.
- TORQUE 20RC has very low adhesive strength, thus it secures the sleeve on the box member and acts as an excellent crack arrester.
- Retaining compounds useful for the present invention include, but are not limited to, some anaerobic cure adhesives.
- the bonding layer is preferably characterized as lacking a strong bonding strength so that the bonding layer formed between the box member and the outer sleeve is sufficiently weak to act as a propagating crack arrester. Therefore, in particular embodiments of the present invention, suitable bonding materials preferably include those that form a bonding layer capable of arresting or blunting the propagation of a crack that begins in the protective sleeve before the crack propagates to the wall of the box member. Such bonding materials may be characterized as having an adhesive or tensile strength that is less than the threshold crack- propagating bonding strength. The threshold crack-propagating bonding strength is the lowest bonding strength at which a crack will propagate from the outer sleeve, across the bonding layer and into the box member.
- a crack may form in the protective sleeve initiated by the nick or scratch.
- the crack may propagate through the outer sleeve to the bonding layer that bonds the outer sleeve to the box member.
- the tension stresses perpendicular to the direction of the crack propagation ahead of the crack tip will reach the bonding layer and try to open the layer by pulling the two sides apart.
- the bonding strength of the bonding layer is equal to or greater than the threshold crack-propagating bonding strength, then the interface will not be broken and the crack will cross the bonding layer and continue propagating through the box member, possibly resulting in mechanical failure of the tubular connection. However, if the bonding strength of the bonding layer is less than the threshold crack-propagating bonding strength, then the interface will be broken before the main crack reaches it, thereby arresting or blunting the crack propagation before the crack reaches the box member.
- the threshold crack-propagating bonding strength is about one- fifth of the general cohesive strength of the solid at the interface. Therefore, in particular embodiments of the invention that include the crack propagation blunting property of the bonding layer, the adhesive or bonding strength of the bonding layer is less than about one- fifth of the general cohesive strength of the box material. For a typical material used for the box member, such as carbon steel, the cohesive strength is about 30 to 80 kpsi.
- the protective outer sleeve of the present invention protects the thin-walled portion of the box member from damage that may possibly cause mechanical failure of the box member during, for example, plastic radial expansion of the connector.
- the protective outer sleeve is sacrificial in the sense that the protective outer sleeve may fail without causing mechanical failure of the tubular connection as long as the protective outer sleeve protects the box member from damage.
- the outer sleeve may be made of any suitable pliable material known to those having ordinary skill in the art. Examples of suitable materials include, for example, ductile steel, stainless steel, steel alloys, copper, brass, tin, aluminum, synthetic thermoplastic, fiber composite materials and combinations thereof.
- the thickness of the outer sleeve may be of any thickness suitable for a given application as known to those having ordinary skill in the art, but is preferably greater than about 0.02 inches and is more preferably between about 0.04 inches and about 0.1 inches.
- Particular embodiments of the present invention further include methods for protecting a box member of a radially-expandable tubular connection.
- the method includes applying a bonding material to form a bonding layer to an outer surface of the box member, inner surface of the sleeve, or both outer surface of the box member and inner surface of the sleeve, disposing the outer sleeve about the box member, and bonding the outer sleeve to the box member with the bonding material.
- the outer protective sleeve may be disposed about the box member at any convenient time.
- the protective sleeve may be disposed about the box member as part of the manufacturing process of the tubular connections, after the tubular members have been shipped to a location or just prior to tubular members being joined together in a tubular connection.
- FIGS. 2A-2C are radial cross-sectional views of a radially-expandable tubular connection.
- FIG. 2A shows a radially-expandable tubular connection 10 that includes a box member 11, an outer protective sleeve 13 and a bonding layer 12 that bonds the box member 11 to the outer protective sleeve 13.
- a notch 14 is shown in the outer protective sleeve 13 as damage inflicted upon the sleeve 13.
- the protective outer sleeve 13 protected the box member 11 from being damaged by being notched itself.
- FIG. 2B shows the radially-expandable tubular connection 10 during its radial expansion.
- the notch 14 in the protective outer sleeve 13 becomes a crack 15 during the radial expansion.
- the crack 15 is shown to have propagated through the protective outer sleeve 13, through the bonding layer 12 and into the box member 11.
- the crack 15 was propagated into the box member 11 because the bonding layer 12 had a bonding strength that was at or above the threshold crack-propagating bonding strength.
- FIG. 2C shows a radially-expandable tubular connection 10, according to the present invention, during its radial expansion.
- the notch 14 in the protective outer sleeve becomes a crack 16 during the radial expansion.
- the crack 16 is blunted or arrested at the bonding layer 12 and does not continue to propagate into the box member 11.
- the crack 16 is blunted by forming a new crack 17 that is perpendicular to the original crack 16, thereby passing through the bonding layer 12.
- the crack blunting thereby effectively eliminates the stress concentration in front of the crack 16, thereby arresting the crack propagation before it reaches the box member 11.
- the crack 16 did not propagate into the box member 11 because the bonding layer 12 had a bonding strength that was below the threshold crack-propagating bonding strength.

Abstract
La présente invention concerne des raccordements tubulaires comportant un élément de boîtier comprenant un filet intérieur, un manchon extérieur disposé autour de l'élément de boîtier et une couche de liaison reliant le manchon extérieur à l'élément de boîtier. Ce raccordement est particulièrement utile pour des raccordements tubulaires d'expansion radiale utilisés dans l'industrie de pétrole et de gaz et sert à empêcher la propagation d'une fissure à travers le manchon de protection dans l'élément de boîtier, notamment lorsque le raccordement tubulaire est soumis à une expansion radiale. Le matériau de liaison peut comporter un adhésif, un composé de retenue, un adhésif de traitement aérobie, une soudure, une brasure, un matériau de soudage ou des combinaisons de ceux-ci. Afin de fournir une couche de liaison qui ralentit ou arrête la propagation de fissures avant que la fissure n'atteigne l'élément de boîtier, la couche de liaison présente une adhérence qui est inférieure à une adhérence seuil de propagation de fissure, qui est environ un cinquième de la force de cohésion de l'élément de boîtier.
