USE OF HEXOSE OXIDASES TO CREATE HYDROGEN PEROXIDE IN AQUEOUS WELL TREATMENT FLUIDS |
摘要 |
<p>A hydrocarbon-bearing subterranean formation may be treated with an aqueous well treatment fluid which contains a hexose oxidase, such as glucose oxidase, mannose oxidase or galactose oxidase. The aqueous well treatment fluid further may contain a viscosifying polymer and an aldohexose. The aldohexose reacts in-situ with the hexose oxidase and molecular oxygen to produce hydrogen peroxide. The hydrogen peroxide may then act as a breaker.</p> |
