Abstract
A downhole casing expansion tool and a method of expanding casings using the same. The expansion tool includes an expansion module for expanding casings and a drive module for driving the expansion module. The diameter of the openhole can be kept consistent by the expansion tool, so that monohole well drilling and completion operations can be carried out. The expansion tool is particularly suitable for constructions in deep, ultra-deep and complex wells.
