Drilling Mud System Well Control Device Kill Manifold
Kill Manifold is an essential well control device for balanced drilling technology.During drilling process,when the normal method of mud circulation through the drill pipe is out of control,kill manifold can be directly connected to mud pump to inject mud into wellhead pump,so that control the pressure of oil&gas well.
Choke manifold is composed of choke valve, gate valve, pipeline, pipe fittings and pressure gage, etc.
When well pressure rises, the choke valve (it falls into three kinds: Manually adjustable, hydraulic and positive) on choke manifold can be turned on and off to release the fluid to control casing pressure. Gate valve can be used for direct blowout. When casing pressure is pretty high,
The pressure class of our company's chokes manifold falls into five class: 14MPa, 21MPa, 35MPa, 70MPa and 105MPa. Also, we can design according to customer demand.
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 the kill manifold. The check valves on the kill manifold only allow injection of kill fluid or other fluids into the well bore through themselves, but don't allow any back follow so as to perform the kill operation or other operations.
The kill manifold consists of check valves, gate valves, pressure gauges and pipelines. The one end of the kill manifold is connected to the drilling spool and the other end is connected to pump. The kill manifold and choke manifold are both designed as per API16C and can be used together. The kill manifold is available from 2000psi,3000psi, 5000psi, 10000psi pressure rating.
