It has the features of simple structure, convenient operation, and high pressure resistance. It is a conventional safety sealing device for preventing blowouts in oil fields.

Casing head is used to support the gravity of technical casing and liner, seal the annular space between pipes in each layer, and provide transition connection for the installation of BOP, tubing head and Christmas tree body. Through the openings on both sides of the casing head body, it can squeeze the cement, monitor the well sinking and replenish the balance fluid.

The tubing head is used to hang the tubing string, seal the annular space between liner and tubing, and connect the casing head and the Christmas tree. There are two side openings on the body for well washing.

Christmas tree is a wellhead device used to production, such as flowing well and ESD production well. It is mainly composed of casing head, tubing head and Christmas tree body.
