Vacuum degasser as the second stage solids control equipment is mainly used to remove gas immerged in mud. It is usually set up between shale shaker and mud cleaner/desander. It ensures proper mud weight pumped down well to prevent potential blowout in drilling. It is a very important equipment in degassing process.

Comprehensiveness of Vacuum Degasser

In unbalanced drilling, now have the degassing equipment – drilling fluids mud/gas separator, it only separates the free gas in drilling fluids, but it can’t eliminate the gas that is not free. Drilling fluids often have gas cutting. The function of vacuum degasser is eliminating the gas that is not free. The equipment developed successfully provides the guarantee for the matched equipment of regular drilling and unbalanced drilling.
 

How to increase efficiency of vacuum degasser in eliminating the gas in drilling fluids?

The bubbles in drilling fluids should expose on the surface since it will rapidly swell and fracture in the negative pressure condition. Gas cutting drilling fluid will remain a certain times in separation chamber. After gas cutting enters, separation chamber will present the turbulent condition flowing. So the degassing effect is decided by the reasonable control of vacuum, the remaining times of gas cutting drilling fluids in degassing chamber and the turbulent condition in degassing chamber.

Degassing chamber vacuum is higher, the bubbles which received the expansionary force in drilling fluids are bigger, the volume expansion is bigger, the buoyancy given by drilling fluids is bigger, then it will be easier for the bubbles to float to the drilling fluid surface to break.
