Wellhead Equipment and Christmas Tree

Wellhead Equipment and Christmas Tree

Wellhead devices and Christmas trees are important equipment for oil and gas extraction, consisting of three parts: casing head, tubing head, and Christmas tree. They are used to connect the casing string, tubing string, and seal the annular space between each layer of casing and tubing. They can also control the pressure of the production wellhead and adjust the flow rate of the oil (gas) wellhead. They can also be used for special operations such as acid fracturing, water injection, and testing.
