    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： Methods and compositions are provided for making a solid material for controlling the release of at least one reactant of an exothermic reaction into a carrier fluid. The method comprises the steps of: (a) mixing a reactant with a polymeric material, wherein the polymeric material is capable of being hydrated, and water, wherein the proportion of water is insufficient to substantially hydrate the polymeric material but is sufficient to make the polymeric material sticky to help bind the reactant into a matrix; and (b) drying the mixture. According to a similar aspect, methods and compositions are provided for making a solid material for use in controlling the release of a catalyst of an exothermic reaction into a carrier fluid for increasing the temperature of a section of conduit used for the production or transmission of hydrocarbon. According to other aspects, the reactant or catalyst is mixed with a binder.
