Abstract: Wellhead control panel is an important equipment in the production process of the offshore oilfield. It is mainly used to control the opening and closing of SSV and SCSSV on the Christmas tree. In addition, it also has functions of emergency shutdown and safety protection of fusible plug loop control of the Christmas tree. Wellhead control panel plays an important role in ensuring the safety and stable production of oil wells. In order to ensure the continuous and long-term operation of the wellhead disk, this paper mainly studies the principle and current situation of the wellhead disk. The existing defects in the design function of the wellhead control panel are found out. Combined with the actual situation, an optimization scheme for the function of the wellhead control panel is proposed.
