Oil Well Control BOP Stack
Oil Well BOP Stack Annualr BOP and RAM BOP
Overview of the Oil Well BOP Stack
BOP Stack is an important part of well-control equipments. The BOP Stacks is composed with Annular
BOP and RAM BOP and applied to control wellhead pressure during drilling,workover operations and
formation testing service to control wellhead pressure effectively prevent the occurrence of the blowout
accident and secure drilling operation.
The BOP stacks are available with various bore size from 71/16" to 29 1/2" and the working pressure
ranks from 500psi to 20000psi. And product specification of BOP Stack is complete, the sulfur
resistance of body fit for NACE MR-0175 requirements,which can be applied to Oil extraction,
Perforation, Logging,Under Pressure Operation,and under-balanced drilling.
