发明名称 High Collapse Resistance Solid Expandable Technology
摘要 Composite tubular casing with hardened material between thin pipe-in-pipe increasing the bending capability of the casing wall delivers high collapse resistance. Solid Expandable technology allows substantial wellbore slimming at the expense of collapse resistance. By combining both technologies, cost effective high collapse resistance wellbore construction can be achieved.
