Application
Choke manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil/gas well in the course of drilling, as it is, the device is adopted to execute new drilling-well’s technique of balance pressure, which can avoid pollution of oil-layer, improve the speed of drilling and control blowout effectively. One end of the device connects with the side flange of BOP spool. When BOP closes, it can control the finite pressure from casing by adjusting the choke valve’s opening, so balanced drilling can work under minimum pressure-difference.
Configuration
The choke manifold consists of choke valves, gate valves, line pipes, fittings, pressure gauges and other components.
Working Principles
When the pressure inside the well rises, opening/closing the choke valves (including manual chokes, hydraulic chokes and positive chokes) on the choke manifold can allow the release of the fluid inside the well so as to control casing pressure, which can be directly blown out through the gate valve if the casing pressure is quite high.
Pressure Ratings
The kill manifold is available in pressure ratings of 14MPa, 21MPa, 35MPa, 70MPa and 105MPa, and also can be available upon customer request.

Choke manifold and kill manifold are important well control equipment in balancing pressure in near-balanced drilling wells during petroleum exploration. Choke manifold controls the casing pressure and maintains the balance inside the well, the soft closing of the well is realized by relieving pressure through the choke valve, through which the casing pressure can directly blow out in order to protect the well.
Choke manifold consists of throttle valve, gate valve, pipeline, pipe fitting, and pressure gauge, etc.
When it is pressurized inside the well, the pressure inside the pipe can be controlled by adjusting the opening and closing of the throttle valve (manual adjustable, hydraulic, and stationary) on the choke manifold to release the liquid in the well. When the casing burst pressure exceeding certain differential pressure, it can open flow directly by the gate valve.
There are five pressure grades for the choke manifold made in our company: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa; we can design and manufacture according to customers’ requirement.
