    摘要: The present invention provides sealing methods and compositions for use in subterranean zones penetrated by well bores. The methods of the invention basically include the steps of preparing a sealing composition which includes an aqueous silicate solution, an epoxide containing liquid and a delayed epoxide hardening agent, placing the sealing composition into a subterranean zone and allowing the sealing composition to set into a rigid impermeable sealing mass in the zone.

    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: Polymeric well completion and remedial compositions which form highly pliable and durable 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 compositions are usually foamed and can contain a gelling agent and a solid filler material to increase the density and/or rigidity of the impermeable mass formed and/or a vulcanizable rubber latex, vulcanizing agent and vulcanizing activator to provide durability and other properties.

    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.
