4 1/16" x 15000 psi Choke Manifold
Wellhead equipment
The choke manifold is necessary well control equipment in effectively controlling kill and carrying out pressure controlling for oil and gas well. The equipment can be used to carry out the new technology of balance pressure drilling. Choke manifold can keep oil formation from pollution and increase drilling speed. The manifold can effectively control well blowout.
The choke manifold consists of choke valves, gate valves, line pipes, fittings, pressure gauges and other components.
One side of the manifold is connected with side flange of BOP spool . Under closing BOP, by opening or closing choke valve to control certain casing pressure and ensure balanced drilling at minimum pressure difference. Besides, the choke manifold can be used to flush well.
