Choke Manifold
1. **Application**
The choke manifold is a critical component used in oil and gas drilling operations to control well kicks effectively and implement pressure control techniques. It plays a vital role in maintaining balanced drilling by preventing formation damage, increasing drilling efficiency, and managing blowouts. One end of the manifold connects to the side flange of the BOP (Blowout Preventer) spool. When the BOP is closed, the choke valve helps regulate the casing pressure by adjusting its opening, allowing for controlled pressure management under minimal pressure differentials.
2. **Assembly & Structure**
The choke manifold consists of key components such as a choke valve, gate valve, pipelines, fittings, and pressure gauges. These elements work together to ensure safe and efficient pressure control during drilling operations. The design allows for flexibility in handling various well conditions and pressures.
3. **Working Principle**
When pressure builds up in the well, the choke valve in the manifold is used to release fluids and control the casing pressure. If the pressure becomes too high, the gate valve can be fully opened to allow for direct blowout, ensuring safety and operational control. This system enables precise regulation of well pressure throughout the drilling process.
4. **Compliance**
The choke manifold is designed and manufactured according to the requirements of API Specification 16C, ensuring it meets industry standards for performance, safety, and reliability.
