摘要： A device is provided for cementing a casing in a well bore. The device includes, on the well head side, a shutter disposed within the casing that controls opening and closing of at least one cementing aperture. The at least one cementing aperture makes an interior of the casing communicate with an annular space situated between an external face of the casing and an internal wall of the well. The device also includes, on the well bottom side, a packer having two expandable liners mounted along the external face of the casing and at least one communication passage between an exterior of the first external liner and the annular volume. The at least one communication passage is situated on the packer side orientated towards the well bottom.

摘要： A stage tool for wellbore annular cementing includes: a main body including a tubular wall with an outer surface and a longitudinal bore extending from a top end to a bottom end; a fluid port through the tubular wall providing fluidic access between the longitudinal bore and the outer surface; a valve for controlling flow through the fluid port between the outer surface and the inner bore; a backup sleeve to act as a secondary closure for the fluid port; and an automatic mechanism for automatically closing the backup sleeve without running in a string to move the backup sleeve.

摘要： A system for successively uncovering a plurality of contiguous ports in a tubing liner within a wellbore, or for successively uncovering individual groups of ports arranged at different but adjacent locations along the liner, to allow successive fracking of the wellbore at such locations. Sliding sleeves in the tubing liner are provided, having a circumferential groove therein, which are successively moved from a closed position covering a respective port to an open position uncovering such port by an actuation member placed in the bore of the tubing liner. Each actuation member comprises a dissolvable plug which in one embodiment is retained by shear pins at an uphole end of a collet sleeve, the latter having radially-outwardly biased protuberances (fingers) which matingly engage sliding sleeves having cylindrical grooves therein, based on the width of the protuberance. In one embodiment, when actuating the most downhole sleeve, the shear pin shears allowing the plug to move in the collet sleeve and prevent the protuberance (fingers) from disengaging.

摘要： A stage tool and a method for stage cementing a wellbore annulus. The method includes: running into a wellbore toward bottom hole with a tubing string to a position in the wellbore; setting the tubing string in the wellbore to create the wellbore annulus between the tubing string and a wall of the wellbore; opening a cementing port through a side pocket structure positioned alongside the tubing string; pumping cement through the cementing port; and closing the cementing port to hold the cement in the annulus.

摘要： A method for cementing an annular space outside of an inner casing of a subterranean well includes running and setting a cement packer assembly into a bore of the inner casing. The cement packer assembly includes a plurality of nails spaced around a circumference of the cement packer assembly. Slips are set and a lower end of each of the nails is pushed through the inner casing with a setting tool to form holes. A middle portion of the nails having a smaller outer dimension than the lower end of the nails is positioned within the holes. Cement is pumped through the inner casing, through the holes and into the annular space. A force is applied to the nails to move the nails through the holes and position a seal plate of each nail against an inside surface of the bore surrounding one of the holes.

摘要： A cementing port collar has an opening sleeve biased from a closed position to an opened position relative to the collar's exit port, and a first restraint temporarily holds the opening sleeve closed. The collar also has a closing sleeve biased from an opened position to a closed position, and a second restraint temporarily holds the closing sleeve opened. During cementing, the first restraint is electronically activated with a first trigger to release the opening sleeve opened so cement slurry can pass out of the collar's exit port to the borehole annulus. When cementing is completed, the second restraint is electronically activated with a second trigger to release the closing sleeve closed to close off the collar to the borehole so the cement can set. The restraints can include bands of synthetic fiber, which are burned by fuses activated by a controller of the collar responding to passage of RFID tags.

摘要： Disclosed embodiments relate to methods and devices for improved liner drill-in operations. Specifically, embodiments may provide the capability to selectively allow rotation of the liner, even once a packer has been set. Typical embodiments might couple a port sealing collar (that can selectively seal or open a port in the liner) to a selectively lockable swivel joint, for example.
