The flame is carried off through the bypass pipe at a safe height, and the well is killed. The well-control equipment is demounted from the flowing wellhead by plasma arc cutting by means of guided and freely movable vertically and horizontally neck having a supported cutting burner with a graphite electrode at the end. The hole is mounted on a screening baffle plate placed on a travelling sledge movable both vertically and horizontally in relation to the flowing wellhead.EFFECT: higher reliability, higher safety and acceleration of demounting the well-control equipment.2 cl, 1 dwg |
