Why install vacuum degasser in drilling fluid system

Vacuum degasser is a obbligato degassing equipment if drill above 2000m wells. It is necessary to install a drilling fluid vacuum degasser for their removal from the drilling fluids since the invading gases may impact mud properties, cause safety risks and affect the lifespan of some equipment.

Each degasser effectively and efficiently removes gases from gas-cutmud, thus ensuring that the proper mud weight is pumped down hole. In doing so, the degassers are able to aid in the prevention of potential blowouts.

Why install vacuum degasser in drilling fluid system

The vacuum degasser uses the suction of the vacuum pump to establish an under balanced pressure area in the vacuum cylinder and causes the drilling fluid into the hollow shaft of the rotator through suction pipe under the atmosphere pressure, and then lets the fluid spray to the walls of the cylinder from the windows on the hollow shaft, now the gas bubble cut in the mud may break and run off in the function of vacuum pump suction to a safe area due to the fluid collision and bubble separator.

As it is placed after the shale shaker, so we call it second stage mud cleaning equipment in mud recycling system. At the same time vacuum degasser can be used as a heavy-power agitator. The vacuum degasser has self-suction function, so it doesn’t need the extra transfer pump to feed the mud.
