Definitions
- the field of this invention relates to pipe connections to be expanded and more particularly pin and box connections and couplings for downhole tubulars to be expanded after makeup.
- Oilfield tubulars are joined at their ends with threads.
- the male or pin thread on a tubular to be run into a wellbore is screwed to the female or box end of the tubular previously run into the wellbore.
- thread designs available for normal well applications that don't involve expansion.
- the load flanks on the thread have spread apart allowing for leakage under pressure conditions.
- the pin or box have failed from stress cracks due to the expansion.
- the pin end of the connected joint shrank longitudinally due to the expansion and curled inwardly putting itself in the way of moving other tools or equipment through the expanded connection.
- the combination of flank separation from expansion and applied pressure allowed fluid leakage to the outside of the connection past the box nose.
- the present invention seeks to address issues of connection failure by addressing issues relating to flank separation, pin end curling and fluid leakage past the box end to the exterior of the connection.
- a variety of embodiments are presented both in the form of a threaded pin and box and coupling type connections. Those skilled in the art will more readily appreciate the scope of the invention from the claims that appear below and the examples relating to the below described preferred embodiments.
- An expandable tubular pin and box connection having a feature of trapping the pin nose after preferably deforming the pin nose plastically in an outward direction away from the longitudinal axis of the connection.
- the box end is held away from the pin wall before expansion so that its tendency to curl inwardly upon expansion causes it to bend against the pin wall for sealing with it.
- the thread profile is also optimized to reduce flank separation as a result of expansion.
- Figure 1 shows a made up pin and box prior to expansion and a detail of the thread profile
- Figure 2 is an alternative embodiment of Figure 1 having a seal in the box and varying wall thickness in the box;
- Figure 3 shows a coupling joint before expansion featuring a soft seal between the tubular ends
- Figure 4 shows a made up coupling before expansion including a metallic seal between the tubular ends.
- the pin 10 is shown threaded to the box 12 in a two-step thread 14 and 16.
- the leading portion of the pin thread 18 preferably makes an angle of about 60° plus or minus about 1/2° with the longitudinal axis 20 as reflected in angle B.
- the trailing side of the pin thread 22, which carries the makeup load, is preferably oriented at angle A with respect to the longitudinal axis 20, where angle A is preferably about 80° plus or minus about 1/2°.
- the pin 10 has a nose 26 that is captured on makeup by a reverse torque shoulder 28.
- Shoulder 28 can have a variety of orientations up to a radial orientation with respect to axis 20.
- the objective is to capture the nose 26 and plastically deform it in a direction away from axis 20. Doing this has several advantages. First, despite longitudinal shrinkage due to expansion, the nose 26 remains captured by shoulder 28. Secondly, since nose 26 is a free end of pin 10, expansion would normally tend to not only shrink it in length but also make it curl inwardly toward the axis 20. Plastically deforming it on makeup resists this curling effect. Additionally, the plastic deformation on makeup also provides sealing contact between the nose 26 and surface 30 on the inside of the box 12 both before and continuing after expansion.
- the box 12 has an end 32 that is cantilevered above pin surface 34, as shown on the left side of Figure 1.
- a projection 36 which can come in a variety of designs and quantities, lifts or maintains end 32 from surface 34 on makeup. Depending on the height of the projection 36 end 32 may either be pushed away from axis 20 or not, upon makeup. However, after expansion end 32 will shrink longitudinally and will also tend to curl inwardly into a sealing contact with pin surface 34 to create an external seal in the vicinity of projection 36.
- Figure 2 is similar to Figure 1 with the addition of a groove 38 in which there is a seal ring 40 to further seal between surface 30 on the box 12 and the pin nose 26.
- the box 12 has a thick section 42 to help retain the pressure rating of the expanded connection, which will thin as a result of expansion.
- a thick section 44 is provided in the thread area on box 12.
- Figure 3 illustrates a coupling connection featuring tubular 46 having a groove 48 at its end to hold a soft seal 50.
- Tubular 52 has a projection 53 to touch the seal 50 when the two tubulars are placed in an abutting relationship.
- a coupling 54 joins tubulars 46 and 52.
- shoulders 60 and 62 located respectively on the tubulars 46 and 52 respectively capture both ends 56 and 58 of the coupling 54. This capture preferably bends the ends 56 and 58 and preferably into the plastic deformation range.
- Tubulars 46 and 52 respectively have projections 64 and 66 for the same purpose as previously described with regard to projection 36.
- the thread surface orientations can also be along the preferred angles described with regard to Figure 1.
- Seal 48 is a soft material, preferably an elastomer, but can be another material that meets the temperature and chemical exposure requirements of the application.
- Coupling 54 is thicker in the threaded region to compensate for anticipated wall thinning resulting from expansion. Upon expansion, ends 56 and 58 will curl into a sealing or a further sealing relationship with tubulars 46 and 52 respectively. The capture of end or ends 56and 58 can also create some sealing contact even before expansion.
- Figure 4 is an alternative to Figure 3.
- ends 56 and 58 are not captured but are still cantilevered over projections 64 and 66.
- the soft seal 48 there is a more rigid ring seal 68 that extends into grooves 70 and 72 respectively in tubulars 46 and 52.
- the seal 68 is sufficiently rigid to hold the ends 74 and 76 together during and through expansion and to help hold those ends against their tendency to curl inwardly due the expansion.
- ends 56 and 58 can still be captured, as described with regard to Figure 3.
- the thread form can preferably have the configuration described in Figure 1.
- surfaces 22 and 24 help keep the thread together during expansion.
- Surface 18 provides ease of makeup.
- the illustrated thread can be quick started or blunt started because the thin feather or incomplete portion of the thread is removed to facilitate makeup.
- the contact between end 32 and projection 36 in Figure 1 could create a metal-to-metal seal even before expansion.
- the coupling 54 can be of a different composition that the tubulars 46 and 52. This allows the use of a more expansion friendly material for the coupling 54 that also can have higher notch tolerance so that it will be less likely to allow stress cracks to form on expansion.
- Single or multi-step threads are envisioned.
- the amount of expansion can be in the order of about 22% and the preferred material is L80 for its high strength against burst and collapse despite a lower ductility when compared to stainless steels.
