To separate the gas effectively in the drilling, so an efficient vacuum
degasser is essential to the safe and productive drilling
solids control system. Since gas is practically insoluble in water, it is
relatively easy to detect and remove. By comparison, gas is easily soluble in
oilbase muds – its detection is more difficult as well as its removal.
Regardless of the composition of the gas encountered, gas existing in the mud
can decrease efficiencies in rig pump, centrifugal
pump and associated operational equipment. The goal is to “Keep the pumps
Operating”.
As the purification equipment of oil & gas drilling
fluids processing system, vacuum degasser actually is used to remove little
invaded gas in drilling mud. It will be set between shale
shaker and mud cleaner/desander. Vacuum degasser separates the gas that
migrates into the drilling fluids by the function of vacuum pump and vacuum
tubular tank. If the gases does not been separated from the drilling fluids, it
may cause well kicked, and increase the total financial cost and timing cost of
the drilling project. If there is no gas migrating into the drilling fluids, the
vacuum degasser would work as a big mud agitator, to enhance the shearing rate
of the drilling mud.
KOSUN vacuum degasser is a special-purpose device for the treatment of
gas-cut drilling fluids.It can be applied to various mud purification systems to
recover mud gravity, stabilize mud viscosity and reduce drilling cost. At the
same time it can be used as a heavy-power agitator in gas free mud.
KOSUN machinery exclusively handling oil & gas drilling fluids solid
control equipment and solid control system, as well as varieties of chemical
agent, such as shale shaker, desander, vacuum degasser, electrical ignition
device, mud cleaner, sand pump, mud agitator, etc. KOSUN has been serving the
oil & gas industry for 20 years since its establishment in 1992, and has
obtained good experience on equipment manufacturing & oilfield service. Any

Mud
agitator is an important part of drilling
mud solids control system. It is mounted on the circulating
tank. The vanes of the agitator dip into the mud to agitate the fluid
uniformly.
Drilling mud agitator drive structure is mainly composed of motor, reducer,
coupling and mixing shaft. The most common types of drilling mud agitator as solids
control equipment is not much.
The following is two types of mud agitator:
Gear drive structure mud agitator: the advantage is higher transmission
efficiency; shortcoming is larger volume, not easy to maintain. Gear drive can
be divided into direct drive and belt drive.
Bevel gear drive structure mud agitator: has the advantage of simple
structure, but also has many shortcomings. For example: due to drive ratio
restriction, if you want to get slow-speed of revolution drilling mud agitator,
must be through the pulley to do a larger reduction, the results not only low
efficiency, but also large volume. This kind of structure is rare in drilling
mud agitator.
Gear reducers are worm type or helibevel type depending on the choice of the
user.
Standard models are available in 20 H.P. & 10 H.P. Capacity
At present most used mud agitator is still worm and gear drive. Worm and gear direct drive has the advantage of simple structure, large gear ratio, high reliability, widely used in mud cleaning system.
In China
solids control industry, KOSUN mud agitator combines compact design with
high torque performance levels necessary for a uniformly suspended flow of
drilled solids throughout the mud systems. Powered by 1500RPM (4 pole) explosion
proof motor and connected through heavy duty gear reducer, this agitator
transfers high torque at RPM to Impeller to perform the most severe mud mixing
conditions.
