摘要： A system comprising a first expandable tubular section and a first expansion bridge coupled to an inner surface of the first expandable tubular section. A base pipe is coupled to the first expandable tubular section and to a second expandable tubular section. A second expansion bridge is coupled to an inner surface of the second expandable tubular section. The system also comprises an expansion cone disposed within and translatable relative to the first expandable section. The expansion cone has an expansion diameter greater than an inner diameter of the first and second expansion bridges and less than an inner diameter of the base pipe.

摘要： A downhole axial expansion or telescoping tool includes radially expandable tubular members. The tubular members are relatively moveable before and after radial expansion, and include an intermediate layer therebetween of a non-metal or non-cladding material. The intermediate layer may provide any one or more of lubricity, load transfer, sealing, and shape retention during and after radial expansion.
