高压抗硫油气井口安全截断系统

Safety control system for high-pressure antisulphur wellhead

为确保高压含硫油气井场的安全而研制的KGS6 5— 70 (10 5 )型高压抗硫油气井口安全截断系统主要由气源过滤调压单元、电子监控仪、气动控制单元、气动感测单元和气动执行单元组成。当井场发生设备气压超高、集输管线爆破失压或火警等其中任一险情时 ,系统均会立即在 3～ 4s内迅速关闭井口 ,截断气源 ,防止事故的发生和蔓延 。

To ensure safety of the well site, a safety control system for high-pressure antisulphur wellhead is developed. The system is mainly comprised of gas source filtering and regulating unit, electronic monitoring meter, pneumatic control unit, pneumatic sensing unit and pneumatic execution unit. By means of this system, the wellhead can be shut down in 3-4 seconds in case of emergency. The operating process and field use of the system is introduced.
