    摘要: Polymeric well completion and remedial compositions which form highly pliable impermeable masses of desired rigidity and methods of using the compositions are provided. The compositions are basically comprised of water, a water soluble polymerizable monomer, a polymerization initiator and an oxygen scavenging agent. The composition is usually foamed and contains a gelling agent and a solid filler material to increase the density and/or rigidity of the impermeable mass formed.

    摘要: The present invention provides improved methods and compositions for sealing a pipe string in a well bore. The methods basically include the steps of preparing a hardenable epoxy sealing composition which hardens into a resilient solid mass having high bond strength comprising an epoxide containing liquid, an organosilane compound and a hardening agent, placing the epoxy composition in the annulus between the pipe and the walls of the well bore and allowing the epoxy composition to harden.
