    摘要: A method for expanding a tubular member in a wellbore includes applying a downward force to an expansion cone through a work string to anchor the tubular member in the wellbore and pulling upwards on the expansion cone with the work string to expand the tubular member. The expansion cone is disposed in a launcher portion connected to the tubular member being expanded.
