Technical Advantages

The Christmas tree, composed of casing head, tubing head and Christmas tree (for oil and gas) body, is a wellhead device used for flowing well, mechanical recovery well, etc., to exploit oil. It is the main equipment for controlling and regulating oil and gas production at the top of oil and gas wells. It is used to suspend the tubing string into the well, seal the annular space of the casing, control and adjust the production of the oil well, and ensure the daily production management, such as operation, construction, oil admission, casing pressure data, testing and wax removal.





Effect

1. Connect downhole casing of each layer, seal the annular space of casing of each layer, and support the weight of casing part.

2. Hang tubing and downhole tools, support the weight of all tubing strings in the well, and seal the annular space between tubing and casing.
3. Control and regulate the production of oil wells.
4. Ensure the construction of downhole operations to facilitate the construction of measures, such as well killing operation and round trip operation, and daily production management such as pressure measurement and wax removal.
5. Receive oil pressure and casing pressure data.
