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. by using blowdown lines connected to then kill manifold. Then increasing well head pressure also can be released directly for bottom hole pressure release. Or water and extinguishing agent can be injected into then well by means of then 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 operati 2.Structure The kill manifold consists of check valves . gate vales, pressure gauges and pipelines . 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 and both designed to APL16C and be used together . The kill manifold is available for pressure ratings of 14MPa , 21MPa , 35MPa and 70MPa . 3 .Operating Requirements (1) working pressure of all pipelines . 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 .
