Abstract
The utility model relating to a Christmas tree wellhead blowout rescue device pertains to a wellhead maintenance device in petroleum exploration projects. Aiming at solving the problem of blowouts caused by the damage of the upper four main through holes of the wellhead flange and washout, the utility model provides a wellhead blowout rescue device with the structure particularly suitable for wellhead Christmas tree. The device is assembled by the up-to-down connections of a lower clip assembly, a vertical adjustment assembly, a radial adjustment assembly, an upper clip assembly. A fixed clip and an outer clip are arranged outside of the upper and lower clip assemblies through adjustment jacks. The vertical adjustment assembly is fixedly and vertically arranged to the radial adjustment assembly through the support assembly. The upper clip assembly is arranged to one end of the radial assembly. The upper and lower clip assemblies tightly clip the anti-blowout device during operation. The fixed clip clips the short segment of the sleeve. The outer clip clips wellhead flange. The lower assembly, the wellhead flange and the short segment of sleeve are fixedly arranged and play thr role of the supporting of the whole device.
