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.

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.
