摘要 |
The composition includes a pH adjusting agent and a precipitation-control agent. The pH adjusting agent provides the hydrolysis of degradable fibers at a temperature of no more than 50° C. and comprises substances that may provide and maintain a high pH environment. The precipitation-control agent allows maximally delaying or completely suppressing the formation and deposition of precipitate during the hydrolysis of the degradable components in the treatment fluid A method of treating an subterranean formations penetrated by a wellbore with the additives described herein comprises providing a treatment fluid comprising a base mixture and a degradable substance, with additionally added degradable materials, and injecting the prepared treatment fluid into the subterranean formation.
