DEGRADABLE CASING SEAL CONSTRUCTION FOR DOWNHOLE APPLICATIONS |
摘要 |
In one aspect, a degradable apparatus is disclosed, including: an inner core with a first degradation rate in a downhole environment; an outer sheath disposed around an outer extent of the inner core with a second degradation rate less than the first degradation rate in the downhole environment. In another aspect, a method of temporarily sealing a downhole zone is disclosed, including: providing an inner core with a first degradation rate in a downhole environment; providing an outer sheath disposed around an outer extent of the inner core with a second degradation rate less than the first degradation rate in the downhole environment; sealing the downhole zone with the outer sheath; exposing the outer sheath to the downhole environment; and exposing the inner core to the downhole environment. |
