Crosslinkable cellulose derivatives |
摘要 |
Novel treating fluid compositions containing crosslinkable non-ionic cellulose derivatives and methods of use in petroleum recovery operations are disclosed. The treating fluid polymers are prepared by reacting vinyl monomers having a crosslinkable substituent with a cellulose derivative using a redox system comprising the reaction product of hydrogen peroxide with ferrous salt. The polymers readily crosslink with polyvalent metal ions, such as zirconium and titianium, to form temperature-stable gels useful in petroleum recovery operations.
