摘要： A downhole apparatus for use in a tubular can include: a mandrel having a first end shoulder; a first slip disposed on the mandrel adjacent the first end shoulder and abutting against a mule shoe; a cone disposed on the mandrel adjacent the first slip and movable relative to the first end shoulder to engage the first slip toward the tubular; a seal element disposed on the mandrel adjacent the cone and being expandable outward from the mandrel; and wherein at least one component selected from the group consisting of the mandrel, the first slip, the cone, the seal element, and the mule shoe is a filler-doped degradable component that comprise a degradable material and a filler.
