Wellhead devices refer to the Christmas tree, tubing head, casing head and related accessories used to suspend, support, control and adjust production equipment. As an important equipment in oil and gas production, the performance of the wellhead device is related to the safe production of oil and gas wells. A lot of research and development has been carried out at home and abroad, but the wellhead devices at home and abroad are still lagging behind the international level. The wellhead device introduces the composition, installation position, working principle and function of the casing head, tubing head and Christmas tree respectively.
The wellhead device is a conventional wellhead device in which the casing head, tubing head, hanger, valve and other components are arranged in a standard manner. The wellhead device can customize the standard configuration of the wellhead device according to the specifications, wellhead devices and casing procedures.
The performance of the wellhead device is related to the safe production of oil and gas wells. The development of the petroleum industry has put forward higher requirements on the reliability and control of wellhead devices and valves, which has promoted the continuous improvement and development of wellhead devices. For the entire wellhead device, the improvement of the wellhead device mainly focuses on reducing the size and weight, that is, portability and flexibility; in terms of structural form, we mainly focus on the improvement and development of gate valves, vigorously promote the use of wellhead devices, and conduct reliability analysis and research on products.
