Single well control system, also named ESD Control Panel. It can simultaneously control subsurface safety valve (SCSSV), Christmas Tree main valve(MSSV) and wing valve (WSSV), and achieve sequential on/off function to reduce the frequency of use of SCSSV and improve its durability and reliability.
It adopts the two-step decompression control principle, which can greatly save the energy loss during use and improve the operation efficiency.
