Choke Manifold
Choke manifold is a necessary equipment to control kick and implement pressure control technology of oil and gas wells. When the BOP is closed, use the opening and closing of the throttle valve to control a certain casing pressure to maintain the bottom hole pressure always slightly higher than the formation pressure, so as to prevent the formation fluid from further flowing into the well. In addition, during well shut in, choke manifold can be used to relieve pressure to achieve soft shut in. When the pressure in the well rises to a certain limit, it is used for blowout to protect the wellhead. When the pressure in the well rises, the fluid in the well can be released to control the casing pressure by opening and closing the throttle valve (manual adjustable, hydraulic and fixed) on the choke manifold. When casing pressure is very high, blowout can be conducted directly through gate valve.
