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 accordance with the teachings of the present invention, a system and method for forming an annular isolator between production tubing and a borehole wall is provided. A section of expandable tubing is installed in a borehole, and a sleeve disposed around a surface of the tubing cooperates with the tubing to form a fluid chamber. The sleeve includes a first portion that is predisposed to expand outwardly under fluid pressure from the fluid chamber, and a second portion that is configured such that, when expanded due to fluid pressure, the second portion stores energy that is biased to sustain the fluid pressure within the chamber, in response to a change in fluid volume. The tubing may be expanded using a tool disposed within the tubing.

摘要： The present disclosure addresses apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. A first deployable annular isolator is carried on tubing as it is positioned in a borehole. An annular isolator forming material is placed in the annulus around the first deployable isolator. The first isolator is then deployed into the material in the annulus to form a combined isolator. The annular isolator forming material is carried in a compartment in the tubing and forced from the compartment into the annulus. A second deployable isolator may be deployed before placing the material in the annulus to resist annular flow of the material before the first isolator is deployed. The second isolator may be deployed by material from the compartment. A second compartment may be provided to deploy the first isolator.

摘要： A multi-layer deformable composite construction. In a described embodiment, a method of expanding a structure in a wellbore includes the steps of: positioning the structure in an unexpanded configuration in the wellbore, the structure including a wall made up of multiple layers; expanding the structure to an expanded configuration while permitting relative displacement between the layers; and then preventing relative displacement between the layers.
