摘要： A cutting tool (22) includes a plurality of pivoted blades (36) for swinging outwardly to an expanded radial position for first cutting the walls of multiple casing strings (10, 11), and then removing a predetermined length of the casing strings (10, 11) simultaneously in a cutting action. Pivoted blades (36) have cutting elements (66) of a similar size and shape positioned about upper, lower, and outer sides (60, 62, 64) of the blades (36). The lower sides (62) of the blades (36) engage the upper annular cut ends of the casing strings (10, 11) in a cutting action without tripping or removal from the bore hole.

摘要： An underreamer for forming a cavity within a well bore is provided. The underreamer may include a housing rotatably disposed within the well bore. The underreamer may also include an actuation rod slidably positioned in the housing. The underreamer may further include a plurality of cutter sets where each cutter set is pivotally coupled to the housing and the actuation rod. The cutter sets are also pivotally coupled together. An axial force applied to the actuation rod operates to slide the actuation rod relative to the housing and extend the cutter sets from a retracted position radially outward relative to the housing to form the cavity when the housing is rotated.

摘要： An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. After expansion a cement retainer positioned at the bottom of the expanded liner and the sliding sleeve located either above the mounting location of the liner in the casing shoe or in the liner below the mounted top section allow cement to be delivered outside the expanded liner and the displaced wellbore fluid to return into the casing through so that the liner can be cemented. The cement retainer can be delivered with either the liner or the expansion tools to allow expansion and cementing in a single trip. A shifting tool can be run on the expansion string to actuate the sliding sleeve and if necessary to allow for cement to be pumped from the drill string into the annulus through the sliding sleeve. The cement retainer can be milled out in a separate trip.

The underreamer may also include an actuation rod slidably positioned in the housing. The underreamer may further include a plurality of cutter sets nested together around the actuation rod while the cutter sets are in a retracted position where each cutter set is pivotally coupled to the housing and the actuation rod. The cutter sets are also pivotally coupled together. An axial force applied to the actuation rod operates to slide the actuation rod relative to the housing and extend the cutter sets radially outward relative to the housing to form the cavity when the housing is rotated.
