    摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

    摘要： In a retrievable packer adapted for service under high temperature and high pressure operating conditions, the packer is purpose-designed as a cut-to-release packer. That is, this retrievable packer has no built-in release mechanism. An internal cinch slip is used to retain the packer in its set position and thereby prevent the accidental release of the packer. The only way it can be released is by severing the mandrel. The cut point is opportunely designed so that the mandrel is severed in a precise location such that not only is the packer released, but all the packer and tail pipe are then retrievable as a unit. The primary advantage of a cut-to-release packer is that it can withstand extreme tubing loads occurring during production and stimulation.

    摘要： In a retrievable packer adapted for service under high temperature and high pressure operating conditions, improved retention of the packer in the wellbore is achieved by use of an inventive slip and wedge system, wherein the cones on the wedges are spaced a progressively slightly greater distance apart from their corresponding slip cones, from the centermost slip cone to the outermost slip cone. This forces the center of the slip to be loaded first. As greater forces are exerted on the wedges from end to end, the wedge will deform slightly and the next cone of the wedge will make contact with its matching portion of slip. Thereby, as the wedges are loaded higher and higher, more wedge cones come into bearing contact with the slip. Further, a barrel slip is used, to provide a uniform circumferential distribution of forces. This design effectively allows initial setting of the packer with very little slip tooth contact area. This permits the slip to quickly get a good grip into the casing wall. Subsequent higher loading brings more and more slip teeth to bear and prevents overstressing the casing.
