Wellhead equipment and Christmas tree are essential for oil and gas exploitation, compassed of casing head, tubing head and Christmas tree, used to connect casing string and tubing string, and seal the annular spaces between all casing at all layers and between pipelines. In addition, it can be used not only to control wellhead pressure and adjust oil/gas wellhead flow, but also for special operations, such as acid fracturing, water injection and testing, etc.
The company integrates the research, development, production, and marketing of wellhead assembly, medium-and high-pressure valves, X-mas, well control throttle pipe assembly, instruments, flowmeters, oil rig brake blocks, etc. We have established a complete inspection system and apply entrie-process-control and inspection, from raw materials, semi-finished products to finished product. Focus on the customer and delivery the maximum value for customers as the management concept, positive enterprising to make a greater contribution to the petroleum drilling.
Oil Extraction Wellhead Functions
Connect all layers of underground casing, seal the annular space of each layer of casing, bearing casing part of the weight.
Hanging tubing and downhole tools, the weight of all tubing strings in the support well, the annular space between the tubing and the casing.
Control and regulation of well production.
Ensure that all underground operations, easy to kill operations, take off operations and other measures for construction and pressure measurement, waxing and other daily production management.
Acquire the data of hydraulic pressure and casing pressure.
Wellhead Tree Maintenance
The maintenance content of the Christmas tree is: keep the equipment clean and leak-free, no oil, no rust, no loose, no missing parts, the switch of each component is flexible and good.
