Compliant cone system

摘要

The present invention generally relates to a cone system having a cone segment capable of deflecting in response to a restriction or obstruction encountered while expanding a tubular. In one aspect, an expansion cone system is provided. The expansion cone system includes a mandrel and two or more pockets disposed circumferentially around the mandrel. Each pocket is at least partially defined by a fin member. The expansion cone system further includes a cone segment coupled to each pocket. Additionally, the expansion cone system includes a biasing member disposed between the mandrel and the respective cone segment. In another aspect, a method of expanding a wellbore tubular is provided.

1. An expansion cone system comprising:
a mandrel; two or more pockets disposed circumferentially around the mandrel, each pocket is at least partially defined by a fin member; a cone segment coupled to each pocket; a first end member and a second end member disposed at each end of the cone segment, wherein each cone segment is independently movable relative to the first end member and the second end member; and a biasing member disposed in each pocket between the mandrel and the respective cone segment.
