Definitions

  • This disclosure relates generally to connected expandable tubular members in a wellbore.
  • this disclosure relates to the radial expansion of tubular members that are connected via a threaded connection offering improved efficiency as compared to conventional expandable threaded connections.
  • a wellbore typically traverses a number of zones within a subterranean formation.
  • Wellbore casings are then formed in the wellbore by radially expanding and plastically deforming tubular members that are coupled to one another by threaded connections.
  • existing apparatus and methods for coupling together and radially expanding tubular members may not be suitable.
  • a series of expanded tubular members can be subjected to elevated axial loads during installation, under pressure loading, even when subjected to significant temperature (e.g., 300 degF) during certain wellbore operations.
  • the maximum axial load that can be applied to a series of expanded tubular members is, in most instances, limited by the threaded connections between adjacent tubular members.
  • connections are often referred to as having an efficiency, which is defined as the tensile rating of the connection divided by the tensile rating of the base tubular.
  • Upsetting has been used on non-expandable tubulars to increase the efficiency of threaded connections.
  • Upsetting is a known forging process that is used to make thicker walls at the end sections of a tubular. The threads of the connection are then machined out of the end sections of the tubular that have thicker walls. The thickness added by upsetting leaves more material after the threads are machined than without upsetting, and the efficiency of the connection is increased.
  • the upset When the added wall thickness is obtained by only increasing the outer diameter of the end sections of the tubular, the upset is an External Upset (EU). When the added wall thickness is obtained by only decreasing the inner diameter of the end sections of the tubular, the upset is called an Internal Upset (IU).
  • the added wall thickness can also be obtained by increasing the outer diameter of the end sections of the tubular as well as decreasing the inner diameter of the end sections of the tubular, sometimes requiring two hits (strikes) to form the upset. In these cases, the upset is called an Internal-External Upset (IEU). Sometimes it takes two hits (strikes). Upsetting is thus expensive to operate. Further, once upset, the tubulars are heat treated to a desired grade. Heat treating to treat the tubulars after upsetting is also expensive.
  • upsetting may present several challenges specific to expandable tubulars.
  • One challenge may be that the thicker wall will increase the force required to expand the connection to a level that may be much higher than the force required to expand the base tubular.
  • Another challenge may be that the thicker wall may not expand uniformly, and thus, the expansion may hinder the connection performance, such as its capability to seal.
  • Yet another challenge may be that the thicker wall may interfere with the inner diameter of the casing or hole into which the tubulars are expanded. Interference with the inner diameter of the casing or hole could drive up the expansion force to an undesirable value.
  • This disclosure describes a method of making an expandable tubular assembly having an expandable threaded connection and/or a wellbore casing.
  • the method may comprise the step of forming an upset end of a first tubular member.
  • the upset end of the first tubular member may have a wall thickness that is greater than a wall thickness of a main body of the first tubular member.
  • the method may further comprise heat treating the first tubular member after forming the upset end.
  • the method may comprise the step of enlarging an inner diameter of an end section of the first tubular member such that the end section has a second inner diameter that is greater than a first inner diameter of the main body of the first tubular member.

  • an expansion cone (not shown) having an expansion diameter that is greater than both inner diameter 18 and inner diameter 34 is moved axially through the tubular assembly 30 so as to radially expand the tubular member 10B, the upset section 32, and then tubular member 10A.
  • the now expanded tubular assembly 30, including the upset section 32 has a substantially uniform inner diameter 40.
  • the thickness of the wall section 42 of the expanded upset section 32 may remain greater than the wall thickness of the main bodies of the tubulars, thus providing added strength in the connection. Because the expansion diameter of the expansion cone is larger than both inner diameter 18 of the main bodies 12 and inner diameter 34 of the upset section 32, both unexpanded inner diameters are expanded to the same expanded inner diameter 40.

Therefore, the disclosed embodiments provide greater resistance to tensile loads, and therefore a greater efficiency, as compared to conventional expandable threaded connections.

  • the enlargement of the inner diameter of the end section has been performed by subtractive manufacturing (e.g., by cutting, milling or grinding).

Further, an inner diameter of an end section of the tubular member 10B is also enlarged, for example by subtractive manufacturing, such that the second inner diameter 34 is preferably at least 103% of the first inner diameter 18.
  • Figure 5 illustrates a portion of the tubular member 10B after the step of machining a pin end 16 in the end section of the tubular member 10B. Again, only one thread is illustrated for the sake of simplicity, but several threads are usually machined. As shown, machining the threaded pin end 16 has been performed by subtractive manufacturing. The subtractive manufacturing preferably leaves a distance 46 between the minor diameter of the threads and the second inner diameter of at least 75% of the wall thickness 20 of the main body 12.
  • the wall section 42 of the threaded connection (shown in Figure 3) has a thickness that is the sum of the distance 44 (shown in Figure 4C) and the distance 46 (shown in Figure 5). Accordingly, the wall section 42 may have a thickness of at least 150% of the nominal wall thickness 20.

Abstract

L'invention concerne un procédé de fabrication d'un ensemble tubulaire dilatable comprenant un raccordement fileté dilatable et/ou un tubage de puits de forage, ledit procédé consistant à refouler des extrémités d'éléments tubulaires, à agrandir des sections d'extrémité des éléments tubulaires, et à usiner une extrémité de broche filetée et une extrémité de boîte filetée. Un raccordement fileté dilatable est formé par mise en prise de l'extrémité de boîte filetée et de l'extrémité de broche filetée. Le raccordement dilatable présente une plus grande efficacité que les raccordements de joints affleurés dilatables classiques sans augmentation inacceptable des forces de dilatation nécessaires à la dilation du raccordement fileté.
