    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 seal and seal assembly for use with well tools, such particularly as well packers, for sealing the annulus between the well packer mandrel and the wall of a well tubing such as casing. The seal is fabricated of an elastomeric-like material comprising fluorocarbon resins, poly arylene ketone, and carbon fibers mounted between end retainer assemblies each comprising a mesh anti-extrusion ring, a tapered mesh backup ring, and a metal backup shoe. The seal has internal longitudinally spaced V-shaped recesses to cause the seal to buckle radially outwardly as it is compressed longitudinally to increase the stress along the middle portion of the seal where the seal meets the well casing inner wall. The seal is useful at high temperatures and pressures such as 550 degrees F. and greater than 15,000 psi.
