    摘要: Systems and methods for placing a tubular, braided sleeve in a well bore. The sleeve is positioned within an interior of a carrier configured to hold the sleeve in an undeployed position, followed by lowering the carrier into the well bore. The sleeve may be used in conjunction with a curable resin that can be solidified to set the sleeve into a tubular cross section. After securing the sleeve to the well bore, the carrier may be moved away from the bottom of the well bore, deploying the sleeve and extending it along the contour of the well bore. The tubular sleeve may then be subsequently expanded in situ to increase its diameter. The curable resin can then cured to make the sleeve substantially rigid.

    摘要: The present invention provides a process for forming cement in a well bore. In this process, a cement composition is formed that comprises a cement and one or more beads mixed with the cement. The cement composition containing the beads is displaced into the well bore, and an inert gas phase is introduced to the cement composition to control a density of the cement composition. The inert gas phase can be introduced by adding a gas generating material to the cement composition and/or a porous material to the cement composition. In an embodiment, the gas generating material is a nitrogen generating material that may be activated by an oxidizing agent. In another embodiment, the gas generating material is a hydrogen generating material, e.g., an aluminum powder. The present invention further provides a cement composition comprising a cement, one or more beads combined with the cement, and an inert gas phase created by, e.g., a gas generating material and/or a porous material.
