    摘要: Methods and apparatus for expanding tubulars are disclosed. The tubulars may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.

    摘要: Apparatus for expanding first and second portions of a downhole tubular in a single trip comprises a support and first and second expansion devices. The first expansion device is mounted on the support and is operable to expand a first portion of tubular. The second expansion device is mounted to a second portion of tubular and is adapted to be engaged by the support following the expansion of the first portion of tubular, and is then used to expand the second portion of tubular.

    摘要: In a downhole assembly (1) including an outer casing or mandrel (2), an axially movable prong (11) in the mandrel, and means for equalizing pressure within the mandrel (1) comprising a fluid duct (7) communicating the interior of the mandrel with the outside and a control member (or melon) (8) movable by the prong to control fluid flow via said duct (7); there is provided apparatus for controlling movement of the prong (11) comprising radially movable arrester dogs (14) engagable with a rib (20) on the prong (11) and an annular piston device (15) located in a housing (16) adapted for operative movement of the dogs (14). In particular housing zones on either side of the piston device (15) are maintained at tool external and mandrel internal pressure respectively whereby the piston device (11) is moved to lock the prong (11) when there is a pressure imbalance but free the prong (11) when pressure equilibrium is reached.

    摘要: An upstroke jar for use in downhole operations in an oil or gas well and for connection between a wireline and a tool comprises a casing defining an anvil and for connection to the tool, a hammer slidable axially within the casing for impacting with the anvil and for connection to the wireline, a hammer holder, a spring arrangement located between an abutment on the casing and an abutment on the hammer holder for compression on an operative movement of the hammer holder as a consequence of tension on the wireline and a connector releasable to free the hammer from the holder at the completion of the operative movement so that the freed hammer may impact with the anvil. The compression load on the spring present at the release is dependant on the extent of the operative movement from a rest position and the degree of compression of the spring means to obtain the operative movement. Adjustment of the release load present at the instant the hammer part is released by the connector is provided.
