Wellhead Choke And Kill Manifold

Kill manifold

Description:
In case of increase of the well head pressure, 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 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 do not allow any backflow so as to perform the kill operation or other operations.

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 are both designed to API 16C and can be used together.

Technical Parameter:

Choke Manifold

Description:
Choke manifold is necessary device to control the well kick successfully and execute the pressure control technology on oil/gas well in the course of drilling. The device 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.

Assembly & structure:
Choke manifold consists of choke valve, gate valve, pipeline, fittings and pressure gauge etc

Specification:
Pressure level is divided into five levels, i.e 14Mpa, 21Mpa,35Mpa,70Mpa and 105Mpa, meanwhile it can be also designed according to the requirements of customer.
