CHOKE MANIFOLD

1. Application

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, as it is, 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 flange of BOP spool. When BOP closes, in can control the finite pressure from casing by adjusting the choke valve’s opening, so balanced drilling can work under minimum pressure-difference.

2. Configuration

The choke manifold consists of choke valves, gate valves, line pipes, fittings, pressure gauges and other components.

3. Working Principles

When the pressure inside the well rises, opening/closing the choke valves (including manual chokes, hydraulic chokes and positive chokes) on the choke manifold can allow the release of the fluid inside the well so as to control casing pressure, which can be directly blown out through the gate valve if the casing pressure is quite high.

4. Pressure Ratings

The kill manifold is available in pressure ratings of 2000PSI, 3000PSI, 5000PSI, 10000PSI, 15000PSI, and also can be available upon customer request.
