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： A packer for use in subterranean wellbores provides efficient utilization of its cross-sectional area with mechanisms therein for anchoring, sealing, and torquing through the packer. In a preferred embodiment, a retrievable packer has a tubular mandrel, rubbers disposed on the mandrel, upper and lower compression members axially straddling the rubbers, a barrel-type casing slip, upper and lower wedges axially straddling the casing slip, a release mechanism, and a series of threaded load-distributing components which help to prevent collapse of the mandrel.

摘要： An expandable sand control screen (100) that is positionable within a wellbore comprises a fluid permeable generally tubular member (102) that is expanded downhole. A filtering assembly is disposed exteriorly of the generally tubular member (102). The filtering assembly includes a filter medium (106) that prevents the flow of particulate material of a predetermined size therethrough but allows the flow of production fluids therethrough. The filtering assembly also includes a compliable member (118) that has a thickness that is radially variable downhole. During or after expansion of the expandable sand control screen (100), the radial variability of the thickness of the compliable member (118) allows the expandable sand control screen (100) to comply with any irregularities in the wellbore profile, thereby preventing any void regions between the expandable sand control screen (100) and the wellbore.
