摘要： An apparatus (10) and method, particularly useful for isolating zones in a hydrocarbon open hole well bore (80). The apparatus includes a tubular body (12), arranged to be run into and secured within the well bore. A sleeve member (14) is positioned on the exterior of the body and is sealed thereto creating a chamber (16) therebetween. Pressure is applied through a port (18) in the body to cause the sleeve member to move outwardly and morph to an inner wall of the well bore. Pressure is trapped in the chamber and maintained at a morphed pressure value by pressure balancing means in the form of a biased piston (64).

摘要： A tubular assembly is disclosed for use in a wellbore (5) of an oil, gas or water well, typically for landing a downhole device in the wellbore. The assembly has a sleeve (1) adapted to receive the body of the downhole device. The sleeve is deployed into a conduit in the wellbore and expanded, so that the outer circumferential surface of the sleeve is radially expanded against the inner surface of the conduit. The sleeve has a bore with an inner circumferential surface comprising an inwardly facing formation adapted to engage with an outwardly facing formation on the body of the downhole device when the body of the downhole device is disposed in the bore of the sleeve. The sleeve is typically deployed in the wellbore at the desired location and is radially expanded by an expander device (2) that is deployed within the bore of the sleeve. The expanded sleeve plastically deforms and retains its expanded configuration after the radial expansion force is removed from the sleeve. The sleeve provides a modular anchoring or landing point in the wellbore that can be retrospectively set in the conduit at different locations, and various downhole devices can then be deployed into the sleeves at predictable depths and a reliable connection can be made with the sleeve. The assembly can typically pass through a smaller diameter before being morphed to seal and anchor in a larger diameter.
摘要翻译：公开了用于油井，气井或水井的井筒（5）中的管状组件，通常用于将井下装置落在井眼中。组件具有适于容纳井下装置的主体的套筒（1）。套筒被部署在井眼中的导管中并且膨胀，使得套筒的外圆周表面相对于导管的内表面径向膨胀。套筒具有内孔，其内周表面包括向内表面的形状，其适于在井下装置的主体设置在套筒的孔中时与井下装置的主体上的面向外的地层接合。套管通常在期望的位置处在井眼中展开，并且通过展开在套筒的孔中的膨胀器装置（2）径向扩张。膨胀的套筒在径向膨胀力从套筒上移除之后塑性变形并保持其膨胀构型。套筒在井筒中提供模块化锚固或着陆点，其可以在不同位置的管道中追溯地设置，并且然后可以将各种井下装置以可预测的深度部署到套筒中，并且可以与套筒进行可靠的连接。组装件通常可以在变形之前通过较小的直径，以便以更大的直径密封和固定。

摘要： A morphable packer and method of setting the packer in a wellbore. The packer is a tubular member having a throughbore with a central portion having a greater diameter than each end portion with tapered portions there between. Gripping elements are arranged on the tapered portions. Morphing of the tubular member creates a seal between the central portion and an outer cylindrical structure, such as a wellbore or casing, and the gripping elements are moved radially outwards to engage with the cylindrical structure. The gripping elements act as slips which are activated by morphing the tubular member. Embodiments are described with the tubular member being a sleeve on a base pipe and, additionally, sealing and securing features in the form of elastomeric bands, lugs and wedges.

摘要： A method and apparatus for creating a joint between tubulars such as tubing, pipes, casing and liner for location in a well bore. A connector (16) in the form of a sleeve is located over the ends of each tubular (12, 14) and the ends of the tubulars are morphed onto the sleeve to provide a metal to metal seal. In an embodiment the sleeve (16) is morphed onto the ends of the tubulars (12, 14). The connector may also have a profiled inner surface with circumferential grooves (266) and a sectioned locating groove (90) to provide axial and torsional load bearing capacity.

摘要： Apparatus and method for sealingly connecting tubular members in a wellbore. In an arrangement where a portion of a tubular member is radially expanded into sealing contact within a second tubular member, and the second tubular member has circumferential recesses on an inner surface, a resilient member protrudes from a side wall of the recesses. The resilient member is acted on by the portion of the tubular member during expansion and maintains sealing contact to the portion after expansion.

摘要： Apparatus and method for securing and sealing a tubular portion to another tubular to provide a liner hanger in oil and gas wells. At the top of the liner string, a sleeve is arranged on the liner to create a chamber therebetween. A port provides fluid access through the liner to the chamber. When fluid is introduced into the chamber the sleeve is morphed to secure it to the cemented casing. A lower fluid pressure is required to morph the sleeve than if the liner itself was to be morphed. Embodiments are provided for securing and sealing arrangements to increase the metal to metal seal and the load capability between the liner string and casing.

摘要： An apparatus and method for securing a tubular within another tubular or borehole, creating a seal across an annulus in a well bore, and centralising or anchoring tubing within a wellbore. A sleeve is arranged on a tubular body to create a chamber therebetween. A port provides fluid access through the body to the chamber. A support frame of bow springs on mounts is located within the chamber. When fluid is introduced into the chamber the sleeve is morphed to secure it to a well bore wall, an end of the sleeve will move along the body and compress the frame and bow springs. The compressed springs support the sleeve to maintain a seal between the sleeve and well bore wall to form an isolation barrier.

摘要： Apparatus and method for filling and sealing a chamber with fluid at a predetermined pressure in a well bore. In a downhole assembly (10) comprising a tubular body (14) having a cylindrical throughbore (18) and a chamber (16) to be filled on an outer surface (26) of the body, a fill mechanism is provided to control fluid flow between the throughbore and the chamber. The fill mechanism includes a sliding seal (72) arrangement at the outer surface which is operated by the fluid flow in the throughbore to allow fluid flow into the chamber and then seal the chamber. Embodiments are described where the chamber is between a morphable sleeve (64) and the outer surface of the tubular, filling of the chamber morphs the sleeve and sealing the chamber at a predetermined fluid pressure secures the tubular within a borehole, creates an annular seal across an annulus or centralizes the tubing within a wellbore.

摘要： A zonal isolation device in the form of an active external casing packer is provided which includes a tubular section such as a casing or liner and at least one sleeve member positioned on the exterior of the casing or liner and sealed thereto. The method detailed herein provides zonal isolation by use of a pair of spaced apart sleeve members during a frac operation where frac fluid is supplied to a zone (in between the pair of sleeve members) requiring to be frac'd, where the frac pressure acts not only on the outside of the zonal isolation device but also on the interior of the sleeve member to enhance the seal provided thereby.

摘要： A coupling system between tubulars such as tubing, pipes, casing and liner for location in a well bore in which profiled sections (46, 50) on the tubulars (12, 14) are connected using a radially applied force to form a metal to metal sealed connection. Embodiments are provided in which the profiled sections are grooved and/or tapered, additional profiles are provided to prevent relative rotation of the tubulars, the radial force is applied inwardly, outwardly or in both directions, and a connector is used as an additional tubular member to form the coupling.
