It is composed of four parts: the casing head, the casing tee, the tubing head and the oil production tree.

It is used to fix the wellhead of the drilling well and connect the wellhead casing string. Seal and control the annular space between the pipes, suspend the tubing, control the pressure at the wellhead and regulate the flow rate of the oil (gas) well, and can induce the oil to the tubing at the wellhead. When necessary, it can also be used to shut down the oil well, and can also be used for special operations such as acidification fracturing, water injection and testing.

Applicable to various casing, tubing programs and various connection methods;

The oil production tree works safely and reliably, and its operation and maintenance are simple and convenient.
