Temperature-Extended Enzyme Systems |
摘要 |
Water-soluble amphoteric surfactants at low concentration thermostabilize enzymes in brine. The thermostabilized enzyme compositions can be used in a method to digest polymers at temperatures and/or salinities at which the enzyme is normally inactivated and/or coagulated without the surfactant. In oilfield applications, the composition can be used in well treatment methods including filtercake removal and polymer viscosity breaking in well treatment fluids.
