JRJ.com, February 20, 2025 — According to information from the National Intellectual Property Administration, Mudanjiang Northern Oilfield Machinery Co., Ltd. has obtained a patent titled "A High-Sealing Leak-Proof Casing Head for Oilfield Wellheads," with authorization announcement number CN 222501683 U, and the application date is June 2024.
The patent abstract discloses a high-sealing leak-proof casing head for oilfield wellheads, belonging to the technical field of oil well casing heads. The technical solution includes a casing head body and a connecting pipe, which are pinned together. Both the casing head body and the connecting pipe have sealing components installed on their respective inner sides facing each other, with the sealing components' surfaces tightly contacting the inner walls of the casing head body and the connecting pipe respectively. The sealing component includes a sealing ring located between the opposing sides of the casing head body and the connecting pipe. This design addresses the issue in existing oilfield wellhead casing heads where, after connection with the inlet and Christmas tree, vibrations caused by the later operation of the oil well's sucker rod can lead to wear between the casing head and the Christmas tree connection pipe, thereby reducing the service life of the sealing structure between the casing head and the Christmas tree, decreasing sealing performance, and affecting usage effectiveness.
