Oilfield Wellhead Equipment API 16C Hydraulic Kill And Choke Manifold
Kill And Choke Manifold Description:
Choke manifold is a system of valves and chokes for controlling the flow from the well usually has two flow paths, one adjustable choke used primarily for cleaning the well up and facilities to install and change choke of fixed sizes for a more accurate flow control during main well flow periods.
Choke manifold is used during well testing, The positive choke has a fixed diameter and the size of the orifice on the adjustable choke can be varied. In addition the adjustable choke allows fixed chokes to be switched out as needed without stopping the well, increasing the flexibility of the overall system.
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 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.
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 14MPa, 21MPa,
35MPa, 70MPa and 105MPa, and also can be available upon customer
request.
5. Operating Instructions
(1) The working pressure of all components on the choke manifold
shall be compatible with that of the BOP stack used.
(2) The choke manifold shall be installed at the place where the
operator can reach it easily. The pressure test must be performed
prior to installation and the seat test pressure shall be equal to
the rated working pressure.
(3) The line pipe shall be level and straight as much as it could.
In case of the turn of the line pipe, the 120 degree steel bent
pipe shall be used. The bore of the line pipe shall be large
enough.
(4) The pressure gauge must be installed.
(5) In winter, the choke manifold can work under a low temperature
condition.
