METHODS TO PLACE FLUID LOSS MATERIALS |
摘要 |
A method of treating a subterranean formation includes providing a treatment fluid comprising a crosslinkable polymer prepared by a redox reaction with vinyl phosphonic acid monomers or polymers and a polysaccharide, and at least one of a hydrolysable in-situ acid generator and a chelating agent, providing a carrier fluid comprising a brine, providing a metal crosslinker, placing all into a formation, allowing the polymer of to crosslink, and allowing the crosslinked polymer to become un-crosslinked. A wellbore fluid includes a crosslinkable polymer prepared by a redox reaction with vinyl phosphonic acid monomers or polymers and hydroxyethyl cellulose; at least one of a hydrolysable in-situ acid generator, a chelating agent, and mixtures thereof; a carrier fluid comprising a brine; and a metal crosslinker. |
