    摘要： An expandable slip ring is used to secure attachment of an expanded tubular to a surrounding tubular. It features elongated generally axially oriented openings separated by narrow segments. As a swage is advanced within a tubular that has the slip ring outside it the narrow segments or tabs expand and can break but the ring is still held to its shape as the expansion progresses due to the integrity of other tabs that can subsequently break as the swage advances within the tubular that is surrounded by the slip ring. The integrity of the slip ring is enhanced for storage and run in while the expansion characteristics are more uniform as the ring retains some structural integrity during much of the expansion process.

    摘要： An improved liner hanger comprises a mandrel having a piston housing and a plurality of spring slots disposed on the outer wall surface of the mandrel. Each spring slot having at least one spring disposed therein. The liner hanger also has a slip housing having a plurality of slips operatively associated therewith, a spring adjustment sleeve, and an adjustment sleeve ring. The location of the spring slots on the outer wall surface of the mandrel permits an increase in the number of springs utilized for setting the liner hanger. The spring adjustment sleeve and adjustment sleeve ring permit easy and safe assembly and disassembly of the liner hanger. Additionally, when actuated to move from its run-in position to its set position, springs, slip housing, and slips all move upward.

    摘要： An apparatus is disclosed to allow efficient setting and release from a liner packer connected to a liner assembly. The polished bore adjacent the packer is protected from debris since the setting procedure takes place while the polished bore remains protected. Movements necessary to accomplish the setting procedure occur principally at the uphole end of the polished bore to minimize adverse effects on the integrity of the polished bore from such movements in an area where subsequent operations require a sealing contact.

    摘要： Disclosed herein is a method of sealing a tieback to a tubular. The method includes, positioning a metal deformable member of the tieback within a tubular and contacting the tubular with a sleeve of the tieback. Moving the sleeve in a first axial direction thereby contacting and radially deforming a first portion of the deformable member by axially compressing the deformable member and sealably engaging the tubular with the radially deformed first portion.
