摘要： Methods of consolidating unconsolidated weak zones or formations and forming chemical casings include drilling a well bore with a drilling fluid having a pH in the range of from about 6 to 10 and that comprises water, a polymeric cationic catalyst which is adsorbed on the mineral surfaces in the weak zone, a particulate curable solid thermoset resin and a delay acid catalyst for curing the solid resin, and forming a filter cake on the walls of the well bore. The filter cake is then contacted with a treating fluid comprising a water soluble or water dispersible polymer which is capable of being cross-linked by a thermoset resin and causing the resin to be hard and tough when cured, and a water soluble or dispersible thermoset resin, whereby the treating fluid components deposit on the filter cake and the thermoset resin cures into a hard and tough cross-linked chemical casing thereon.

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.
摘要翻译：使用在地层中原位聚合的水溶性聚合物的锚固剂提供方法。锚固剂包括与地下地层中的矿物表面的一个或多个悬挂的羟基反应的可水解甲硅烷基，以形成“固定”到矿物表面的“硬”键。选择锚定剂具有用于与水溶性聚合物共价连接的另一官能团。这可以帮助水溶性聚合物锚定在地层中的矿物表面。因此，认为水溶性聚合物的单分子层将形成并锚定到矿物表面，这将为基质提供优异的弹性。预计单分子层不会干扰基质的渗透性。
