    摘要: Methods are provided using an anchoring agent for a water-soluble polymer that is in-place polymerized in a subterranean formation. The anchoring agent comprises a hydrolyzable silyl group that reacts with one or more dangling hydroxyl groups of a mineral surface in the subterranean formation to form “hard” bonds, “anchoring” to the mineral surface. The anchoring agent is selected to have another functional group for covalent attachment to the water-soluble polymer. This can help a water-soluble polymer be anchored to a mineral surface in a subterranean formation. Accordingly, it is believed that monomolecular layers of water-soluble polymer will be formed and anchored to the mineral surface, which will provide excellent elastic properties to the matrix. The monomolecular layers are not expected to interfere with the permeability of the matrix.

    摘要: Methods of consolidating formations or forming chemical casing or both while drilling are provided. One method of the invention comprises drilling a well bore with a drilling fluid comprised of water, a polymeric cationic catalyst which is adsorbed on weak zones or formations formed of unconsolidated clays, shale, sand stone and the like, a water soluble or dispersible polymer which is cross-linked by a thermoset resin and causes the resin to be hard and tough when cured, a particulate curable solid thermoset resin, a water soluble thermoset resin, and a delayed dispersible acid catalyst for curing the solid and water soluble resins. The drilling fluid forms a filter cake on the walls of the well bore that cures and consolidates the unconsolidated weak zones and formations penetrated by the well bore so that sloughing is prevented and forms a hard and tough cross-linked chemical casing on the walls of the well bore.
