Audited Supplier Inside BlowOut Preventer (IBOP) is a special tool, which can be stripped through the BOP preempt to be connected with the added drilling tools as soon as possible. When the blowout occurs during lifting operations, the IBOP have many advantages in situation such as, high pressure rating, reliable seal, easy application and operation.
When the drill tool is lifted out of the hole, blowout could happen due to suction. In event of a blowout, the open position of the IBOP valve allows back flow, easing the installation process. Upon successful installation, the valve can be promptly closed with a relief rod to prevent further back flow. Fluid can then be pumped in from the surface to discharge the IBOP and drill string. The purpose of the blowout prevention can be achieved by the following generic steps: discharging the relief sub; regulation of fluid; commence pump circulation.
When ordering please specify the connection of drill string.
