Methods for treating a subterranean formation with a treatment fluid containing a gelling agent and subsequently breaking the gel with an oxidizer |
摘要 |
A method is provided for treating a zone of a subterranean formation penetrated by a wellbore. The method includes a step of introducing a treatment fluid into a zone of a subterranean formation through the wellbore, wherein the treatment fluid comprises: (i) water; (ii) a gelling agent comprising a polymer grafted with a vinyl phosphonic acid or derivative thereof; and (iii) a crosslinking agent, and the step of subsequently introducing an oxidizer into a zone of a subterranean formation through the wellbore. According to another aspect the method includes a step of introducing a treatment fluid into a zone of a subterranean formation through the wellbore, wherein the treatment fluid comprises: (i) water; (ii) a gelling agent comprising a polymer grafted with a vinyl phosphonic acid or derivative thereof; and (iii) a magnesium oxide; and the step of: introducing an acid into the zone through the wellbore.
