摘要： A method of forming a kickoff plug in a borehole is disclosed. The method includes a first phase in which the interval to be cemented is treated to remove gelled mud and mud cake from the walls of the borehole and in which drilling fluid is conditioned for subsequent cementing operations. The method includes a second phase in which a hydrostatically balanced plug of a hydraulic cement slurry is placed in the interval to be cemented and then permitted to harden to form the kickoff plug. Each phase of the method features the injection of high velocity streams of fluid, e.g. drilling fluid and cement slurry, into the borehole in a plane or planes which are substantially parallel to the cross section of the borehole and at linear velocities sufficient to cause circulation of gelled mud, mud cake, and drilling cutting from the borehole.

摘要： A method and apparatus for use in setting sidetrack plugs in a well bore. The apparatus comprises an inflation packer assembly which may be attached to the lower end of the tubing string. The packer is inflated to seal against the well bore at the lower end of the sidetrack plug. The inflation packer is attached to a tubing string with a length of tail pipe. The tail pipe is releasably attached to the tubing string. After the inflation packer is sealed against the well bore, a cementitious fluid is circulated above the bladder to form the sidetrack plug. The tailpipe is then released and the tail pipe and the inflation packer remain in the hole and form a part of the sidetrack plug. An additional embodiment includes a whipstock connected to the inflation packer assembly.

摘要： A casing packer apparatus includes a mandrel having a mandrel exterior, a longitudinal mandrel bore defined therethrough, and a power port defined in the mandrel communicating the mandrel bore with the mandrel exterior. A packer element is concentrically received about the mandrel. An annular piston is concentrically received about the mandrel and has an annular differential pressure area defined thereon and communicated with the mandrel bore through the power port. The annular piston and packer element are operably associated so that the packer element is set by sliding motion of the piston in response to increased fluid pressure in the mandrel bore. Either a compression set packer element or an inflatable packer element may be utilized.
