Christmas tree is a wellhead device used for oil extraction, such as blowout wells and machine wells. It is the main equipment for controlling and regulating oil and gas production at the top of the oil and gas well. Wellhead X-mas tree is the cross-over between the wellhead casing and the flowline to the production process.It controls and regulates the wellhead pressure and the flow of hydrocarbon fluids and enables the well to be shut off in an emergency. It assembled with a series of Upper master valves, Lower master valve, Production Valve, spools and adapter flanges fitted on top of the well, and used for controlling the well pressure during oil well production, drilling, fracturing operation.It is used for extracting two oil reservoir at the same time and also independently. It allow put down two tubings into the same casing. It can seal the different two oil reservoir with dual packer and single packer.
