发明名称 Methods of degrading filter cakes in a subterranean formation
摘要 Many methods are presented including one that comprises: providing a well drill-in and servicing fluid comprising an aqueous fluid, a viscosifier, a fluid loss control additive, a bridging agent, and an orthoester composition; using the well drill-in and servicing fluid to drill a well bore in a subterranean formation; allowing the well drill-in and servicing fluid to establish a filter cake in at least a portion of the well bore; contacting at least a portion of the filter cake with a breaker fluid comprising an orthoester composition; and allowing at least a portion of the filter cake to degrade.
