Oil Gas Production Christmas Trees
The casing head ,a component conneting the casing to the wellhead assembly of various types and sizes ,is used to support the both the intermediate (protective) string and the production string ,and to seal up the annular space between the casings,thus providing a crossover connection for the installation of the bop ,the tubing head,the Christmas tree and other top wellhead components. It is also used to inject additional cement slurry or balance fluid,monitor the well sink,and execute other operatins through both of the two bypass holes in the casing head body.
The casing head ,which is of standard structure ,is fitted with a complete set of casing head hangers manufactured by ZS,which are Available for choice according to different requirements of casing procedure and wellhead conditions.the top part of the body is API6B or API6BX flanged.
