Zhongyuan Oilfiled is a complex block oilfield and casing failure has a serious impact on oilfield development in the later stage. Entity expansion pipe technique was developed in 2005 and great breakthrough was made in expansion pipe ma-terial, coupling, sealing and expansion technologies. They have advantages such as big bore size after repair, reliable sealing, high strength, corrosion-resistant. The total technology reached the international advanced level and applied in casing plugging, water layer blockage and casing bonding. Up to the end of 2008, the technology has been applied in 21 wells successfully. The largest downhole depth reaches 3450m and the longest patch borehole section is 53m. Casing patch technology using expandable pipe adaptable to deep, high temperature and pressure, highly mineralized wells has formed and can be popularized and applied further.
