Choke Manifold / Kill Manifold

The choke and kill manifold is a necessary device for successful control on well kick and implementation of oil and gas well pressure control technologies. It is designed, manufactured and inspected in accordance with 16C.

Choke manifold consists of choke valves, gate valves, line pipes, fittings, pressure gauges and other components. It 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.

Kill manifold consists of check valves, gate valves, line pipes, pressure gauges. In case of increase in well head pressure, the kill manifold can provide a means of pumping heavy drilling fluid into the well to balance bottom hole pressure so that well kick and blowout can be prevented. In this case, by using blow down lines connected to the kill manifold, the increasing well head pressure also can be released directly for bottom hole pressure release. or water and extinguishing agent can be injected into the well by means of kill manifold.
