Kill Manifold

1. Application

In case of increase of the 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, the increasing well head pressure also can be released directly through blowdown lines

connected to the kill manifold so as to release bottom hole pressure, or the water and extinguishing agent

can be injected into the well using 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 do not allow any backflow so as to
perform the kill operation or other operations.

2. Configuration

The kill manifold consists of check valves, gate vales, pressure gauges and line pipes. The one end of the kill
manifold is connected to the drilling spool and the other end is connected to the pump. The kill manifold and
choke manifold are both designed to API 16C and can be used together. The kill manifold is available in pressure

ratings of 14MPa, 21MPa, 35MPa and 70MPa.

3. Operating Instructions

(1) The working pressure of all line pipes, gate valves and check valves shall be compatible with that of the
BOP stack used.

(2) The kill manifold is not intended to be used as common lines for pouring drilling fluid.
