Description

87621993 LINER INSTALLATION WITH INFLATABLE PACKER CLAIM OF PRIORITY [0001] This application claims priority to U.S. Patent Application No. 16/001,688 filed on June 6, 2018. TECHNICAL FIELD [0002] This disclosure relates to using inflatable packers within a wellbore. BACKGROUND [0003] An inflatable packer is a type of packer that uses an inflatable bladder to expand the packer element against a casing or well bore. A drop ball or a series of tubing 10 movements are sometimes necessary to prepare for setting the inflatable packer. Inflatable packers can be inflated using hydraulic pressure provided, for example, by applying pump pressure. Inflatable packers are capable of relatively large expansion ratios, which can be useful in through-tubing work where the tubing size or completion components can impose a size restriction on devices designed to set in the 15 casing or liner below the tubing. SUMMARY [0004] This disclosure describes technologies relating to usmg inflatable packers within a wellbore, for example, to install a liner. [0005] Certain aspects of the subject matter described here can be implemented 20 as a method. A well tool is positioned within a well bore. At least a portion of the well tool is secured within an inner volume defined by a sleeve while the well tool is positioned within the well bore. After positioning the well tool within the well bore, the sleeve is moved relative to the well tool to expose the previously secured portion of the well tool. After moving the sleeve relative to the well tool, an inner diameter of the well 25 tool is increased to at least an outer diameter of the sleeve. After increasing the inner diameter of the well tool, the sleeve is removed from the well bore through a region of the well tool defined by the increased inner diameter of the well tool. [0006] This, and other aspects, can include one or more of the following features. WO 2019/236271 PCT/0S2019/032953 [0007] The well tool can include an inflatable packer. Increasing the inner diameter of the well tool can include inflating the inflatable packer. [0008] Moving the sleeve relative to the well tool can include applying a pressure on a rod coupled to the sleeve. The rod can be positioned within the inner 5 volume defined by the sleeve. The rod and the sleeve can move together relative to the well tool in response to the applied pressure. [0009] Moving the sleeve relative to the well tool can include moving the sleeve relative to the well tool along a longitudinal axis of the well tool. [0010] The well tool can be coupled to a hollow member defining a seat. The 10 rod can pass through the hollow member to couple to the sleeve. [0011] The rod can be received in the seat to cease movement of the sleeve. [0012] The deformable liner can be secured within the well bore before removing the sleeve from the wellbore. [0013] Certain aspects of the subject matter described here can be implemented 15 as a method. While a well tool is positioned within a wellbore, an outer radial surface of the well tool is covered with a sleeve. After the well tool is positioned within the well bore, the outer radial surface of the well tool is exposed by moving a rod coupled to the sleeve. An inner diameter of the well tool is increased. The sleeve is removed from the wellbore through a region of the well tool defined by the increased inner 20 diameter of the well tool. [0014] features. [0015] This, and other aspects, can include one or more of the following Increasing the inner diameter of the well tool can include increasing the inner diameter of the well tool to at least an outer diameter of the sleeve. 25 [0016] Increasing the inner diameter of the well tool can include inflating an inflatable packer of the well tool. [0017] The well tool can include a deformable liner defining the inner diameter of the well tool. The inflatable packer can be positioned within the deformable liner, such that inflating the inflatable packer causes the deformable liner to deform 30 [0018] The inflatable packer can be a first inflatable packer. The well tool can include a second inflatable packer positioned around the deformable liner. [0019] After increasing the inner diameter of the well tool, the deformable liner can be secured within the well bore using the second inflatable packer. 2 WO 2019/236271 PCT/0S2019/032953 [0020] Certain aspects of the subject matter described here can be implemented as a system The system includes a well tool configured to be positioned within a wellbore. The system includes a sleeve defining an inner volume. The sleeve is configured to secure at least a portion of the well tool within the inner volume while the 5 well tool is positioned within the wellbore. The system includes a hollow member positioned within the inner volume and coupled to the well tool. The system includes a rod positioned within the inner volume and coupled to the sleeve. The rod passes through the hollow member to couple to the sleeve. The
