Problems solved by technology

[0002] Conventional RTU valve rooms in oilfields generally adopt the architectural structure, that is, between valve groups and power distribution instrument cabinets, and most of them are located in remote areas, unattended, and the environmental conditions are relatively harsh, resulting in poor geographical environment for valve rooms. Land acquisition is difficult, construction requirements are high, commissioning time is long, civil works are relatively large, construction period is long, and comprehensive investment is high, which does not meet the needs of short pipeline engineering period and fast investment, and the whole is difficult to move and cannot be reused
