What is the structural composition of the oil production wellhead?

Wellhead equipment refers to Christmas trees, tubing heads, casing heads and related accessories used to suspend, support, control and adjust production equipment. As an important equipment in oil and gas production, the performance of wellhead devices is related to the safe production of oil and gas wells. A lot of research and development have been carried out at home and abroad, but the wellhead equipment at home and abroad still lags behind the international level. The wellhead device introduces the composition, installation position, working principle and function of casing head, tubing head and Christmas tree.

A wellhead device is a conventional wellhead device in which casing heads, tubing heads, hangers, valves and other components are arranged in a standard manner. Wellhead equipment can be customized according to specifications, wellhead equipment and casing procedures to customize the standard configuration of wellhead equipment.

The performance of the wellhead is related to the safe production of oil and gas wells. The development of the petroleum industry puts forward higher requirements for the reliability and control of wellhead devices and valves, and promotes the continuous improvement and development of wellhead devices. For the entire wellhead device, the improvement of the wellhead device mainly focuses on the size reduction and weight reduction, that is, portability and flexibility; in terms of structure, we mainly focus on the improvement and development of the gate valve, and vigorously promote the wellhead device. Use, and perform reliability analysis and research on the product.
