The wellhead equipment and Christmas tree are important equipment for oil exploration and they are composed of three part : casing head, tubing head and Christmas tree. The wellhead equipment is used to mount the wellhead to connect the casing string at the wellhead ,to seal and control
circular space between the casing ,to suspend the tubing .to control pressure at the wellhead and
to regulate the flow rate of oil/gas) wells. When necessary, it can be used to close the well or in
special operations such as compressive fracture and acidizing, water injection and testing.
X-mas/Christmas tree is a key equipment to control the pressure in wellhead and adjust the flow rate of Pressure in oil/gas production operation.
It can be designed into general or integral structure as required;
It can be completed with pneumatic/hydraulic safety valve;
It can be classified into two kinds of single-wing and dual-wing.
As required, matched choke may be positive choke or adjustable choke alternatively
