Rotating BOP

Rotating BOP is a rotating diverter, which divert the drilling fluid from the drilling floor and set up a barrier between the annular space and drilling floor. The barrier can withstand some pressure while drilling, so that the under balanced drilling can be carried through. It can be widely applied in under balanced drilling, natural gas and air drilling, work over and normal drilling to effectively decrease cost, reduce damage on formation by mud and increase production of the oil well.

Rotating BOP is also named as rotating controlhead, which is the indispensable equipment to implement the under balanced drilling. As the requirement of environmental drilling is becoming more and more severe, Rotating BOP will be applied to normal drilling. Rotating control head installs on Annular BOP or Ram BOP, to seal off rotating drilling tool and divert fluid whenimplementing under balanced drilling. After assembling with hydraulic BOP, check valve, gas separator and pressure balance pipe tripping pressure device, which can implement under balanced drilling and pressure balance pipe tripping safely. Rotating BOP plays an important role in liberating hydrocarbon zone, preventing drilling, gasified liquid drilling and pressure balance workover.
