Abstract

Un fluido de perforación que incluye un polímero degradable por peróxidos y una fuente de peróxido encapsulada. El polímero degradable por peróxido puede ser un polisacárido. La fuente de peróxido puede incluir un peróxido inorgánico, incluyendo peróxidos de zinc y metales alcalino térreos, tal como peróxido de magnesio. El material encapsulante puede ser un polímero, incluyendo polímeros entéricos. La liberación de peróxido, generalmente de fuentes de peróxido, puede ser controlada por medio del pH de modo tal que se pueda activar la fuente de peróxido y liberar el peróxido debido al cambio en el pH. En una perforación, este cambio de pH se puede efectuar utilizando los fluidos producidos para disminuir el pH de un fluido de perforación más básico.
