Oil&gas field usage vacuum degasser for drilling mud and drilling mud degasser

Why use vacuum degasser for drilling mud?

During the drilling process, the gas contained in drilling fluids from wells affects the mud property, brings hidden danger, and shortens the service life of some equipment. So, it is necessary to install a vacuum degasser to eliminate gas from the mud.

Degasser's Specifications

The basic principle of drilling mud degasser

Vacuum degasser utilizes negative pressure by the vacuum pump to withdraw entrained gases from the mud. In order for this to work, mud is pumped through a venturi, which develops a negative pressure in the vessel by vacuum pump, thus sucking mud into the unit. The choice between horizontally- or vertically-mounted units are typically based on the footprint requirements of the specific rig.

The functions of vacuum degasser

Vacuum Degasser is a special-purpose device and a new type one for the treatment of gas in the drilling fluids. It can get rid of various gas of invasive drilling quickly. Vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity, and reducing drilling costs. Also, at the same time vacuum degasser can be used as a heavy-power agitator and supported applicable to all types of mud circulation purification systems.

Vacuum Degassers are able to service the needs of any application. It is usually installed after the shakers. Each degasser effectively and efficiently removes gases from gas-cut mud, thus ensuring that the proper mud weight is pumped downhole. In doing so, the degassers are able to aid in the prevention of potential blowouts. Unlike the traditional vacuum degasser, APZCQ vacuum degasser is a self-contained unit, Aipu Vacuum Degasser is monitored by level sensor to protect over suction of the fluids. The gas-cut mud is drawn into the degasser by a vacuum created by a regenerative vacuum without needing a centrifugal pump. Aipu degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter.

Degasser's Features and Advantages:

• Scientific reasonable design for the structure, it can get effective gas fluids separation, filter out impurities to guarantee vent pipe always clear.
• Adopt belt drive, avoid the complication of the reducing gear, ensure the long working time without trouble.
• The water circle type of vacuum pump is always at a constant temperature, applies to pump the flammable and explosive.
• High degassing efficiency, up to 95%.
• There is a gas-water separator in vacuum degasser, which can avoid the gas and fluids are all removed together, and also can supply water for vacuum pump, saving water and environment-friendly.
