Choke Manifold

Choke manifold is a necessary device in the process of blowout control and implementation of oil and gas pressure control technology. In case that the BOP is off,  the pressure at the bottom of well shall be kept higher than formation pressure through controlling casing pressure with choke valve on-off.

Additionally, soft shutin can be realized through relieving pressure with choke manifold in the process of well shut-in.When pressure in well reach at an extreme limitation,  it can be used to prevent blowout and protect wellhead. Choke manifold composes of choke valve, gate valve,  flanged pipe and pressure indicator.

Working Principles: 

When the pressure in well increases, the pressure can be

relieved by opening and closing the choke valve

(manual, HYD and fixed) on choke manifold.
