Vacuum degasser design and operation in fluids solids control

Vacuum degasser is set behind shale shaker but ahead of all other equipment.

Design of vacuum degasser

The vacuum degasser shall draw suction from the compartment immediately downstream from the sand trap. When the sand trap is in use, flow to the degasser compartment shall be over a long, high weir.

While the degasser is in use, there shall be no tank bottom equalization between the degasser compartment and those adjacent to it. The degasser capacity shall be at least equal to the planned circulation rate in all of the hole intervals in which gas intrusion is considered to be a hazard

Vacuum degasser operation

Operate degassers to receive all drilling fluid from the lowest portion of the borehole (“bottoms”) after trips. Crews should be familiar with start-up procedures and provide regular checks to confirm that the equipment is working properly

Calculate the volume fraction (percent) gas or air in a drilling fluid by dividing the difference between pressurized drilling fluid density and unpressurized drilling fluid density by the pressurized drilling fluid density, and multiplying this fraction by 100. The calculation can be expanded to include the possibility of dissolved gas by subtracting from 100 % the mass of unpressurized drilling fluid divided by the mass of the same volume of degassed drilling fluid, expressed as a percentage

Aipu degasser information

Aipu degasser including ZCQ240, 270, 300, and 360. Popular model is ZCQ300 capacity is up to 300m³/h. Our vacuum degassers don’t request feed pump. It is self-suction pattern under the minus pressure

Furthermore, it can be used as big mud agitator during fluids drawing. For oil drilling mud system, if well deeps 3000m or more we’ll operate vacuum degasser as safety insurance

Aipu vacuum degasser is rather popular with clients. Repeat orders tell the truth and reflect product quality.
