摘要: A technique utilizes blocking members to resist contraction of expandables in wellbore environments. The technique comprises an expandable having a wall with a plurality of expandable cells. A plurality of blocking members cooperate with at least some of the cells to resist contraction of the expandable device once transitioned to a desired expanded state.

摘要: A system for expanding tubular structures. The system comprises a mandrel that is moved through the center of a tubular structure to increase the diameter of the tubular structure via deformation. The system utilizes an expansion device having a mandrel with multiple segments moved between a contracted state and an expanded state. In one embodiment, the mandrel segments are spring biased to permit a degree of independent movement of each mandrel segment with respect to the other mandrel segments.
