发明名称 METHOD OF EXPANDING A TUBULAR ELEMENT IN A WELLBORE
摘要 A method is disclosed of radially expanding a tubular element in a wellbore formed in an earth formation. The method comprises arranging the tubular element in the wellbore whereby a lower end portion of the wall of the tubular element extends radially outward and in axially reverse direction so as to form an expanded tubular section extending around a remaining tubular section of the tubular element, whereby an annulus is defined between said expanded and remaining tubular sections. The expanded tubular section is axially extended by moving the remaining tubular section downward relative to the expanded tubular section so that said lower end portion of the wall bends radially outward and in axially reverse direction, and load transfer means is positioned in the annulus, the load transfer means being arranged to transfer a load between the remaining tubular section and the expanded tubular section.
