摘要： A telescoping joint is used to space out ends of a string and distribute the string weight between the tie-down locations. The joint can be compressed to reduce its length but has a locking mechanism that prevents extension under tensile loading. The seals in the joint provide a longer service life due to minimization of relative movement in the expansion joint components. The locking mechanism is preferably a ratchet system that uses a body lock ring that is enabled after breaking a shear pin.

摘要： A subterranean tool can drop multiple objects to landing locations in a tubular string. The tool can keep at least one ball out of the fluid stream until ready for release. A dart or wiper plug can be kept in the fluid stream with an open bypass until axial mandrel movement allows release of the plug or dart. The tool is rotationally locked at a lower location for run in and then can rotationally lock at an upper location upon release of the dart or ball. Axial movement that releases the dart can continue until the ball aligns with a decreasing depth groove so that relative part rotation cams the ball against a leaf spring detent and into the mandrel flow path.

摘要： A liner hanger has slips held by a slip body. A potential energy force to move the slips axially when the hanger is in position is selectively released. The nature of the loading between the slips and the casing changes from a radial reaction force from the casing going into the slip and then distributed circumferentially to the slip housing to an essentially axial loading of the slip housing down onto the slip that has penetrated the casing with an opposite reaction force in the casing wall. The contact location between the slip housing and the slip is made broader at the slip end with a wider portion having an undercut to reduce contact stress and to aid in promoting flow past the set slip. The slip housing also has axial flow channels that interact with the undercut to promote flow past the set slips.

摘要： A liner hanger has slips held by a slip body. A potential energy force to move the slips axially when the hanger is in position is selectively released. The slips move axially and radially outwardly guided on opposed edges by the slip body. The slip faces have wickers that dig into the surrounding casing that will support a liner string off the slips. Weight is set down to bring the housing into contact with the top of the slips that are already engaged to the surrounding casing. The nature of the loading between the slips and the casing changes from a radial reaction force from the casing going into the slip and then distributed circumferentially to the slip housing to an essentially axial loading of the slip housing down onto the slip that has penetrated the casing with an opposite reaction force in the casing wall.

摘要： An annularly shaped modular debris barrier can be mounted to an internal or an external member that are spaced apart to define an annular gap that could collect debris. The modules rotationally lock. Modules have circumferential segments that can be initially spaced apart to promote flexing that can occur when there is relative axial movement between the structures that define the annular gap. The gaps between segments are circumferentially offset as between adjacent segments to create a labyrinth through which the fluid can move in opposed direction while at the same time causing the debris to be retained. The segments stay in a flexed condition to exert a contract stress on the free ends thereof that touch the adjacent structure.
