ABSTRACT:
A centralizer is disclosed for stabilizing a radially expandable tubular element extending in a wellbore drilled into an earth formation. The centralizer has a tubular member selected from a section of the tubular element and a sleeve surrounding the tubular element, and at least one centralizer blade, each blade including a first arm connected to the tubular member in a manner allowing the first arm to hinge relative the tubular member between a radially retracted position and a radially extended position thereof, and a second arm connected to the tubular member at a point circumferentially spaced from the point of connection of the first arm to the tubular member. The second arm has an end part connected to the first arm so as to induce movement of the first arm from the retracted position to the extended position upon radial expansion of the tubular member.
