Introduction Of Choke Manifold And Kill Manifold 

Throttle manifold：

The choke manifold is the necessary equipment to control the kick and implement the pressure control technology of oil and gas wells. When the blowout preventer is closed, use the opening and closing of the throttle valve to control a certain casing pressure to maintain the bottom hole pressure to always be slightly greater than the formation pressure, and to prevent the formation fluid from flowing into the well. In addition, when the well is shut in, the choke manifold can be used to relieve the pressure to achieve a soft shut-in. When the pressure in the well rises to a certain limit, it is used to blow out to protect the wellhead. When the pressure in the well rises, the throttle valve (manually adjustable, hydraulic and fixed) on the choke manifold can be opened and closed to release the fluid in the well to control the casing pressure. When the casing pressure is very high, it can be discharged directly through the gate valve.

Kill manifold：

The kill manifold is an important part of the oil and gas well pressure control equipment. Its function is: when the drill string cannot be circulated normally, the drilling fluid can be pumped into the well through the kill manifold to achieve the purpose of controlling the well pressure. One end of the kill manifold is connected with the side hole of the drilling four-way, and one end is connected with the drilling mud pump.
