摘要： A casing patch system comprising a base tubular with two anchor/seals coupled to the base tubular and an expansion tool comprising two expansion devices positioned such that upon expansion of the first anchor/seal, the second expansion device engages the second anchor/seal, which allows reduction of the expansion forces due to sequential expansion and reduces the length of the displacement necessary for setting the casing patch, eliminating the need for resetting the thruster, which allows deployment and setting of the casing patch on a wireline. In another embodiment, the expansion device comprises two swages coupled to a shaft at a distance between them approximately equal to the length of the anchor/seal. The swage diameters are selected such that the expansion forces of the anchor/seal by front and back swages are approximately equal, resulting in significantly less expansion force compared to the expansion force necessary for expansion by a single swage, which allows a high degree of anchor/seal expansions unachievable by single swage expansion devices.

摘要： An apparatus, method, and system for repairing wellbore casing. In one embodiment, an expandable casing patch system for a wellbore includes a casing patch deployment apparatus. The casing patch deployment apparatus includes a shaft having a frontward end and a rearward end as well as a thruster and a main expansion swage disposed on the shaft. The casing patch deployment apparatus also includes an anchor disposed on the shaft. The anchor is disposed frontward of the main expansion swage. In addition, the casing patch deployment apparatus includes a front expansion swage disposed frontward of the anchor and attached to the shaft. The front expansion swage has a diameter less than a diameter of the main expansion swage. The expandable casing patch system also includes an expandable casing patch.
