DRILLING CHECK VALVE

The main functions and purpose of the drilling check valve (KOB):

• Backflow Prevention:

The drilling check valve is used to prevent backflow of drilling mud, gas or oil from the well back into the system, which is important to control pressure and prevent contamination of the external environment. This helps to avoid accidents such as gas or oil releases to the surface.

• Ensuring safety:

The valve plays an important role in ensuring the safety of drilling and production operations. It blocks the flow of oil, gas or drilling mud in case of sudden pressure changes or other unforeseen situations, preventing possible accidents.

• System Pressure Control:

A drilling check valve helps maintain normal pressure in a drilling rig or system, preventing pressure fluctuations that could lead to unpredictable consequences such as equipment destruction or substance leakage.

• Drilling Equipment Protection:

This valve protects equipment from overloading and damage that can occur if fluid or gas starts moving in the wrong direction. This is especially important to protect pumps, pipes, and other system components that could be affected by overpressurization.

• Drilling Mud Circulation Control:

The valve helps maintain efficient circulation of drilling fluid, which is necessary to remove cuttings and rock fragments from the well, as well as to cool the drilling tools.

Advantages of using a Drill Back Valve (BV):

• Safety: It prevents emergencies such as gas or oil leaks by blocking backflow.

• Pressure Maintenance: The valve helps control the pressure in the drilling system by preventing pressure fluctuations.

• Equipment Protection: Protects pumps and other system components from damage caused by pressure fluctuations.

• Drilling efficiency: Maintains normal circulation of drilling fluid, improving the efficiency and safety of drilling operations.

• Drilling Back Pressure Valve (BVP) Application:

• In drilling: To prevent backflow of drilling mud, gas or oil and control pressure during drilling.

• During production: To prevent gases and liquids from flowing back into the system, especially during field development.

• During repair and maintenance: To protect drilling equipment from damage due to pressure fluctuations.
