Christmas tree wellhead device

Various types of oil production wellhead devices are mainly used for oil production and injection well water injection and oil and water well operations in terrestrial self injection wells, pumping unit wells, and electric pump wells. They also have functions such as environmental control testing and water exploration in the annulus. Its characteristics are simple structure, small size, stable performance, and easy operation.

1) The KY65-21 (25) oil production wellhead device has two types: self jetting wellhead device and pumping well wellhead device. When the oil well has self spraying capability and the wellhead pressure is not greater than 25MPa, a self spraying wellhead device can be used; When the oil well has no self spraying ability and needs to be pumped for oil production, a pumping wellhead device can be used. When the self spraying ability of the oil well is strong, this wellhead device is a self spraying wellhead device. When the self spraying ability of the oil well gradually decreases, it is very convenient to replace the bare rod seal to change the self spraying wellhead to a pumping wellhead.

2) The KY65-35 oil wellhead device and Christmas tree are connected by flange connection, which has the characteristics of easy installation, quick disassembly and assembly, reliable sealing, and long service life of valves.

3) The manufacturing of Christmas trees follows API SPEC 6A version.

Wellhead equipment and Christmas tree equipment 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 and tubing string, seal the annular space between each layer of casing and tubing, and 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.
