Pneumatically Controled Drill Accessories Kit Kill Manifold Working Pressure 10000 Psi

Kill Manifolds

Introduction

Kill manifolds are used to forcibly inject heavy drilling fluid, fresh water and fire extinguishing agent into the well to carry out well-kill operation, prevent well kick, blowout or fire, and fire suppression operation after fired. It can be open flowed through flow out pipeline directly to release bottom pressure of the well.

Technical Parameters

Working Pressure: 35~140MPa(5000~20000PSI)

Nominal Diameter: 52~103mm(2 1/16"~4 1/16")

Temperature Level: -46℃~121℃(level L-U)

Specification Level: PSL3,PSL3G

Performance Level: PR1

Manufacturing Standards:API 16C

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.

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.

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.
