摘要
采气井口安全截断新装置安装于气井井口与地面场站设备或输气管线之间。当输气压力(信号压力)达到或超过调定压力(场站设备或输气管线的额定承受力)或场站管线因破裂漏气而造成压力突降时,控制系统将迅速自动关闭液动截断阀,截断井口气源,以自动保护地面场站设备与输气管线。采气井口安全截断装置由液动截断阀(平板阀)与液压控制装置两大部份组成,具有原理科学、结构紧凑、操作简单、安全可靠、易于维护等特点,该系统获得两项国家实用新型专利,2009年6月经专家鉴定,其结论为:该装置设计和制造完全符合API规范要求,与同类产品相比,具有集成程度高、密封性能好、操作方便灵活、性能稳定可靠等优点,基于液压控制的采气井口安全截断系统属国内首创,该项技术总体居国内领先,达到国际同类产品先进水平。
Gas well wellhead safety shutdown system is installed between the wellhead and ground station facility or gas pipe line.The control system will automatically shut down the hydraulic gate valve,cutting off the gas supply when working pressure(signal pressure)reached to or surpass the rated pressure(the nominal capacity of station facility or gas pipe line)or the pressure suddenly dropped when the pipe line broken and gas leak.Therefore it can automatically protect the surface station facility or gas pipe line.This gas well wellhead safety shutdown system consists of hydraulic gate valve(parallel valve)and hydraulic control system.It has the features of scientific principle,compact structure,simple operation,safe & reliable,easy maintenance etc.This system gained two new national practical patents.It was identified by expert on June,2009,that the design and manufacture of this equipment is completely accord with API requirements.Compared with the similar products,it has some advantages,such as high integration,well sealing capability,convenient and flexible operation and stable performance etc.This hydraulic control wellhead shutdown system is the initiate in China,and its overall technical level is on top in domestic and reached the international advanced level of similar products.
