API 16c Drilling Manifold Kill/Choke Manifold
Choke manifold is an essential component used in well control operations to manage well kicks and maintain pressure during oil and gas drilling. When the blowout preventer is closed, the choke valve can be adjusted to regulate casing pressure, ensuring that bottom hole pressure remains slightly higher than formation pressure, preventing further influx of formation fluids into the well. Additionally, the choke manifold allows for a controlled shut-in when the well is closed, and it can also be used to release pressure safely, protecting the well structure from overpressure.
The choke manifold consists of key components such as choke valves, gate valves, pipelines, pipe fittings, and pressure gauges. There are different types of choke valves available, including manually adjustable, hydraulic, and positive-acting models. The choke valve is used to control fluid flow and manage pressure, while the gate valve can be used for direct blowout in emergency situations. When the casing pressure becomes too high, the choke manifold plays a critical role in releasing pressure and maintaining safe operating conditions.
Our company offers choke manifolds with five pressure classes: 14MPa, 21MPa, 35MPa, 70MPa, and 105MPa. Custom designs are also available to meet specific customer requirements. Below is a detailed specification table for our choke and kill manifolds:
In addition to standard models, we also provide customized solutions tailored to specific applications and environments. Our products are manufactured to meet international standards and are widely used in oil and gas exploration, drilling, and production operations worldwide. With a strong focus on quality and safety, we ensure that all our choke manifolds are reliable, durable, and designed for optimal performance under challenging conditions.
