Definitions

  • This invention overcomes the drawbacks of this method, by offering a tool which allows liners to be placed in position by means of the sand-line cable on the drilling rig, saving considerable time, particularly at sea, and eliminating the effect of heaving, if the liner is being installed from a floating rig.
  • This tool for the installation of production liner comprises a non-recoverable connection attached to the liner and containing an internal circular groove, a tool component which fits inside this connector, with an end fitting to which the cable is attached and at least one aperture facing the groove in the connector, a system to lock the tool component to the non-recoverable connector, consisting of a sleeve which moves a locking device through each aperture in the tool component, by sliding inside the component, from a locking position in which the device locks the component to the connector, to an unlocking position, in which the de-' vice retracts, releasing the connector, and a releasable stop blocking this sleeve in the lock position, with means of releasing this stop, thereby releasing the sleeve and allowing it to move into the unlocking position.
  • each locking device consists of a ball, which rests on the outer surface of the sleeve when in the locking position, and in the unlocking position fits into a groove on the sleeve.
  • the upper end of the tool is surrounded by a casing which slides over the outside of the component during unlocking, thus blocking the apertures and retaining the balls.
  • the releasable stop consists of one or more balls and an upper sleeve containing a groove, which slides inside the tool component, from a position in which the sleeve is attached to the tool component by a removable connection, and the ball rests on the outer surface of the vsleeve, pressing against a shoulder on the tool component and a seat on the lower sleeve, to a second position in which the ball retracts into the groove on the upper sleeve.
  • the removable connection between the tool component and upper sleeve consists of a shearing pin.
  • the means of releasing the stop consist of a block, guided by the cable and left-hand side of this FIGURE shows a cross section of the tool assembly in the lowering position, and the right-hand side shows it in the raising-position, after the liner has been installed.
  • the tool component (4) fits inside this connector, with circular apertures (5) opposite the groove (3), and an end fixture (6), containing a suspension ring (7) in two parts, held in position by a stop ring (9), and by means of which the tool is suspended on the cable (8).
  • This sleeve contains a circular groove (13), and balls (14), in the apertures (5) on the too component press against its outer surface.
  • the removable stop comprises an upper sleeve (16) containing a circular groove (17), .and balls which press against the outer surface of the upper sleeve, against a shoulder (18) on the tool component, and against a seat (19) consisting of the bevelled inner edge of the end of the lower easing (10).
  • the upper sleeve (16) is connected to the tool component (4) by a shearing pin (20), and contains a cable guide (21), in two parts, held in place by a stop ring (22).
  • This tool operates as follows;
  • the tool component (4) attached to i the cable (8), is locked to the connector (I) screwed to the liner, by means of balls (14), held in position by the lower sleeve (10).
  • This sleeve is held in the locking position by balls (15), which press against a shoulder (18) on the tool component (4).
  • the pin (20) maintains the whole assembly in the locking position.
  • the tension-meter on the winch on the surface detects separation of the connector and liner from the tool.
  • a non-recoverable connector having an internal diameter substantially as great as that of said liner, said connector being formed with an internal circular groove (3);
  • recoverable tool component (4) and cable means slidably supporting said recoverable component within said connector, said component having at least one aperture facing the groove in said connector when said tool is fastened to said connector;
  • means for attaching said tool component to the nonrecoverable connector comprising locking means (14) which project from the apertures in the tool component into said groove when in locking position;
  • a main sleeve for moving said locking means into and out of said groove by sliding inside the component between a locking position in which said sleeve holds said locking means in said groove to connect said component to said connector and a release position in which said sleeve permits said locking means to depart from said groove, thus releasing said connector, said main sleeve being supported by and removable with said tool component;
  • said locking means comprises at least one ball, which rests against the outer surface of the sleeve when in the locking position and fits into a groove in the sleeve when in the unlocking position.
  • a tool as claimed in claim 2 in which the upper end of the tool comprises a casing slidably encircling said tool component, and retained above the connector by a shoulder on the component when said locking means are in locking position but positioned to cover the apertures in said tool component and prevent escape of said at least one ball from said apertures when said locking means are in their release position.
  • the releasable stop comprises at least one ball and an additional upper sleeve containing a groove, which upper sleeve is mounted to slide inside the tool component, from a position in which the upper sleeve is attached to the tool component by a releasable connection, and the ball rests on the outer surface of the upper sleeve, pressing against a shoulder on the tool component and against a seat on the main sleeve, to a second position in which the ball retracts into the groove on the upper sleeve.
  • a tool as defined in claim 4 in which the means for releasing the stop consists of a block, guided by the cable and adapted to break the releasable connection between the tool component and upper sleeve by striking the upper sleeve.
