Definitions

  • Oilfield tubulars that are used within oil and/or gas production wells include reeled systems, coiled tubing, expandable slotted tubing (EST) , expandable tubing, accessories to well tubulars and drill pipes.
  • Oilfield tubulars that are used outside a well are offshore and onshore pipelines for the transport of crude oil and/or natural gas, risers that extend between the waterbottom and a platform deck, and tethers for mooring tension leg platforms .
  • elongate strings of well tubulars and accessories have to be inserted into the well to drill the well and protect the well against caving in and to facilitate a safe production of oil and gas through the well.
  • the conventional way of protecting a well against caving in is to create a casing by screwing together one or more strings of casing pipes that are lowered into the well and cemented in place. Production of oil and gas takes place via one or more elongate production strings, consisting of production tubes that are interconnected by screw thread couplings, which production strings are suspended within the interior of the casing.
  • a significant problem with the conventional screw thread connections is that if the wall strength at the location of the joint needs to be similar to that of the rest of the tubular the accumulated wall thickness of the pipes at the location of the joint needs to be significantly more than that of the rest of the pipe.
  • the presence of such bulbs at the locations of the joints and the requirement that the string of tubulars must be lowered into the well leads to the requirement of a significant spacing between the external pipe wall and the internal wall of a surrounding tubular such as a casing or the borehole wall.
  • operational requirements normally require that the minimum spacing between the casing and nominal tubing size is at least 2 cm at each side of the tubing wall. This requirement leads to a significant unused annular space around the production tubing and thus to a reduced production capacity of the well or an increased well size.
  • the present invention aims to provide a method and device for joining well and other oilfield tubulars and accessories thereof in an efficient and safe manner.
  • the device should be easily movable such that it can be mounted on a drilling, workover or other oilfield rig, such as a pipelaying vessel.
  • the method should be able to be performed by drilling operators without broad expertise of welding technology, while use can be made of existing hoisting and rig equipment.
  • the method for joining well tubulars comprises the steps of: lowering a first tubular element into a well until the upper end of the element is located in a substantially vertical orientation near the entrance of the well, hoisting a second tubular element to a substantially vertical position above the first tubular element, positioning a body of amorphous material between the adjacent end surfaces of said first and second tubular element, fixing the tubular elements in axial alignment with each other using clamp means which include an internal mandrel which is inserted into the interior of the first and second tubular element, placing an induction coil and seal mechanism adjacent the end surfaces to be joined, - flushing the area to be joined with an inert gas, inducing the clamp means to press the end surfaces of said tubular elements against the body of amorphous material to ensure intimate contact between said end surfaces and amorphous material, - activating the induction coil to melt the amorphous material and create a metallurgical bond between the tubular elements, releasing the clamp means and seal mechanism, and lowering the interconnected tub
  • the device for joining well tubulars comprises: means for maintaining a first tubular element in a substantially vertical position suspended in a well while the upper end of the element is located near the entrance of the well, means for hoisting a second tubular element to a substantially vertical position above the suspended first tubular element, - means for fixing said tubular elements in axial alignment with each other, means for positioning amorphous material between the adjacent end surfaces of said tubular elements, an induction coil and seal mechanism arranged adjacent to the adjacent end surfaces of the tubular elements means for purging the area to be bonded with inert gas and for activating the induction coil to melt the amorphous material, thereby creating a metallurgical bond between the tubular elements on cooling, and means for lowering the interconnected tubular elements into the well.
  • the substantially vertical orientation of the tubular elements during the amorphous bonding process has the advantage that the upper end of the first tubular element, which is suspended in the well, can be firmly fixed near the drilling floor whereupon the second tubular element can be hoisted on top of the first element by means of e.g. a crown block of the drilling rig so that the amorphous bonding process can be carried out with a relatively small mobile bonding device which does not require a heavy foundation frame.
  • the interior and exterior of the tubular elements in the region of the amorphous ring are purged with inert gas. In general it is preferred that this is achieved by providing a sealed chamber externally around the area to be bonded and introducing the inert gas prior to initiating the heating cycle. It is also preferred that the interior of the tubular elements will be sealed during the purging/sealing process by arranging cup seals on a mandrel which is positioned inside the tubular elements during the welding process which has the additional benefit that contact between the heating elements, heat affected zones and any flammable gases that may escape form the well will be avoided.
  • the mandrel is further equipped with a pair of clamps that are positioned opposite to the external clamps on the tubing end sections so that during the bonding process the tubular elements are clamped between the pairs of internal and external clamps which allows a high contact pressure to be exerted by the clamps to the tubular elements without the risk of deformation or rupture of these elements.
  • the present invention also relates to a method and a device for joining oilfield tubulars for use outside a hydrocarbon fluid production well.
  • Examples of such tubulars are pipelines for the transport of crude oil and/or gas, offshore risers and tethers for mooring tension leg platforms.
  • the method according to the invention for joining oilfield tubulars for use outside a hydrocarbon fluid production well comprises the steps of: - positioning a body of amorphous material between adjacent end surfaces of a pair of oilfield tubulars that are to be joined; arranging an amorphous bonding device near said end surfaces, which device is equipped with an induction coil and with clamp, seal and inert gas injection mechanisms; inducing the clamp mechanism, which includes a mandrel that is inserted into the interior of the tubulars, to press the end surfaces against the body of amorphous material and such that the end surfaces are maintained in an accurately defined axially aligned position relative to each other; activating the seal mechanism to create a sealed chamber that encapsulates the end surfaces and the body of amorphous material; activating the inert gas injection mechanism to fill the sealed chamber with an inert gas; activating the induction coil to heat the body of amorphous material such that it melts and on cooling a metallurgical bond is created between the end surfaces of the tubular
  • the device according to the invention for joining oilfield tubulars for use outside a hydrocarbon production well comprises a clamp mechanism, which includes a mandrel that is insertable into the interior of the tubulars, to press the end surfaces against a body of amorphous material between the tubulars such that the end surfaces are maintained in an accurately defined axially aligned position relative to each other; a seal mechanism for creating a sealed chamber that encapsulates the end surfaces and the body of amorphous material; an inert gas injection mechanism for filling the sealed chamber with inert gas; an induction heating coil for heating the body of amorphous material such that it melts and on cooling a metallurgical bond is created between the end surfaces of the tubulars; and means for moving the tubulars into and from the device .

  • the tubulars are preferably moved into and from the device using a ramp or rolling guide assembly.
  • the method and device according to the invention are applicable to all pipe sizes used in well and other oilfield tubulars and can be applied to all materials conventionally used for well and other oilfield tubulars, including carbon steels, high chromium alloys such as 13 Cr, 22 Cr and 25 Cr, titanium and non- corrosion resistant metals.

  • the internal mandrel is essential to reduce the risk of damage to the interconnected tubular elements by the external clamp means of the bonding device.
  • the string of well tubulars that is suspended into the well may have a length of several kilometres and that on a floating or other offshore rig the wellhead may make oscillating movements which require clamp means that are able to exert extremely high clamping forces to the tubular elements in order to properly fix the adjacent tubular ends against each other during the amorphous bonding process .
  • Figure 1 shows an amorphous bonding device consisting of a mandrel 1 and an external portion 2 arranged around a first and a second tubular element 3 and 4, respectively, which elements are to be interconnected by the amorphous bonding device to a string of well tubulars.
  • the external portion 2 of the device consists of a set of sealing elements 5 and 6 for use in maintaining an inert atmosphere in a thus formed external annular chamber 16 at the bonding zone, a means for introducing and removing the inert gas 7 and 8 into and from the external annular chamber 16, an induction heating measurement and control system 9 and 10 and a set of adjustable external clamps 11 and 12 used for aligning the tubular elements and applying axial pressure to the bonded area.
  • the internal mandrel 1 of the device consists of a mandrel that is run into the top tubular element 4 on a hydraulic line 13. The mandrel is at each end equipped with clamp and seal sections 14 and 15. The seals and clamp sections 14 and 15 are hydraulically opened and closed with fluid pressure being supplied by the hydraulic line 13.
  • a preferred procedure for joining well tubulars using the system shown in Figure 1 is as follows:
  • the external portion 2 of the bonding device is mounted or suspended in a substantially vertical position above the wellhead 20 of the well in which the well tubulars are to be inserted, for example to create a casing string or one or more production strings.
  • the tubular elements 3,4 for use in the string or strings are stored in a slant or vertical orientation in a pipe rack near the wellhead, and the external portion of the bonding device is located above the well (not shown) .
  • a first tubular element 3 is then retrieved from the pipe rack and lowered through the external portion 2 of the bonding device into the well until the upper end of this element is located in a vertical orientation just above the lower clamp 12 of the external portion 2 of the bonding device, whereupon a ring of amorphous material 16 is placed for example on top of the first tubular element 3.
  • the internal mandrel 1 of the device whilst it is suspended on the hydraulic line 13 carried by for example the crown block of a drilling rig mounted above the well, is lowered through the second tubular element 4 until the mandrel 1 protrudes about halfway from the lower end of this element 4.
  • the mandrel 1 is clamped to the inner wall of the second tubular element by activating the upper clamp/seal assembly 14 of the inner mandrel assembly 1 by using hydraulic fluid energy via the hydraulic line 13, whereupon the mandrel 1, with the second tubular element 4 attached thereto, is hoisted to a vertical position above the first tubular element 3.
  • the lower part of the mandrel 1 is stabbed through the ring of amorphous material 16 into the upper end of the first tubular element 3 until the lower end of the second tubular element 4 rests upon the amorphous material 16 on the upper end of the first tubular element 3.
  • a high clamping force R is applied to the clamps 11 and 12 of the external assembly 2.
  • a high radial clamping force may be exerted between the clamps and the walls of the tubular elements 3 and 4 without the risk of deformation or rupture of these elements.
  • the amorphous bond is made by activating the coil 9 to inductively heat the tubular elements 2 and 3 to predetermined temperatures for predetermined times whilst applying predetermined axial pressure A via the clamps 11, 12 .
  • Lengths of heating and cooling times together with required pressures to apply are a function of the material to be bonded and will differ for each material. Exact temperature profiles of the materials is monitored and controlled using control instrumentation contained in control system 10.
  • a heat treatment of the bond and interconnected ends of the tubular elements 3 and 4 may be carried out carried out by further inductive heating and cooling as required.
  • Pressure testing of the bond is preferably also carried out by utilising the inert gas injection and containment system provided by the annular chambers 17 and/or 18 as previously described.
  • the cooling of the amorphous bond is carried out by pumping and/or recycling inert gas through the annular chambers 17 and 18. Therefore the annular chambers 17 and 18 contribute to creating a most versatile light weight and mobile amorphous bonding tool which is able to make and inspect an amorphous bond quickly.
  • both annular chambers 17 and 18 will be closed and filled with stationary inert gas during the heating step.
  • inert gas will be pumped at such a speed through the chambers 17 and 18 that the amorphous bond is cooled at the desired rate.
  • inert gas pressure in one of the chambers 17 or 18 is elevated to trace any inert gas leakage through any gaps between the bonded surface.
  • the mandrel 1 and external portion 2 of the device are released from the tubular elements 3 and 4 by releasing the internal seal/clamp assemblies 14, 15 and the external seal/clamp assemblies 5, 6 and 11, 12.
  • the bonded tubular elements will be lowered using the rig equipment to place the manufactured bond across an e.g. X-ray and/or ultrasonic inspection assembly at or near the wellhead 20.
  • the bond area will be finally inspected by said inspection assembly to check for any flaws in the bond .
  • a next tubular element or accessory may be connected on top of the second tubular element 4 by repeating the bonding process described above, which process may be repeated again and again until the string of well tubulars has its required length.
  • the amorphous bond material was placed on the first tubular element 3 during the bonding process.
  • An alternative would be that an end of the first and/or second tubular element 3 or 4 is prepared with an amorphous element attached to it prior to placing the tubular elements on top of each other.
  • tubular ends have been prepared to tolerances suitable for use in the bonding system.
  • An alternative would be to place the tubular elements 3 and 4 in the amorphous bonding device and firmly clamp them in position using the clamping systems 11, 14, and 12, 15.
  • the ends of the tubing could be prepared using a metal milling/dressing system which ensures that the ends of the tubulars are flat and true by milling off a portion of the tubular elements. This milling process could be carried out using milling machinery mounted on an arm (not shown) that swings into position prior to the installation of the mandrel 1 and external portion 2 of the bonding device.
  • inert gas may also be pumped into this chamber 18 via the external chamber 17 and the gap between the amorphous ring 16 and tubular ends before the bond is made and before the internal sealing rings that form part of the internal sealing and clamping system 14 and 15 are activated.

Abstract

Un procédé pour relier des éléments tubulaires utilisés dans les puits et d'autres éléments tubulaires utilisés dans les champs pétrolifères par fixation avec un matériau amorphe, comprend les étapes consistant à positionner un corps (16) en un matériau amorphe entre les surfaces terminales adjacentes d'une paire d'éléments tubulaires (3, 4) utilisés dans les champs pétrolifères et qui sont à réunir, et à faire appel à un chauffage par induction pour fondre le matériau amorphe et créer en refroidissant une liaison métallurgique entre les éléments tubulaires (3, 4). Pendant le processus de chauffage et de formation de la liaison, les éléments tubulaires (3, 4) sont immobilisés en étant alignés axialement, au moyen d'un dispositif de serrage comprenant un mandrin (1) introduit à l'intérieur des éléments tubulaires (3, 4) de sorte que le processus de formation de la liaison peut se faire dans une chambre étanche (17, 18) remplie d'un gaz inerte.
