Description
The quad BOP has a four-ram configuration to provide positive protection against blowouts and to secure the well in emergencies. This permits work to be carried out, under pressure, on surface equipment while the tubing is still in the wellbore. The quad features separate blind seal rams and shear rams, as opposed to a combination shear/seal ram design in the tri-modular BOP. The BOP is placed directly above the wellhead. It can effectively prevent blowout accidents during workover, drilling, completion, and other operations to achieve safe construction. The equipment has a simple structure, easy operation, convenient use and maintenance, small volume, lightweight, and high pressure.
