Vacuum Degasser - oilfield equipment

on . Posted in News

Vacuum degasser is a special and indispensable equipment during the drilling mud processing system. It is located behind the shale shaker to wipe off the invading air.It plays an important role in recalling drilling mud proportion, keeping drilling mud performance. Otherwise, it also could be used as a agitator with big power which suitable for variable kinds of drilling fluids purification system.

Vacuum Degasser

» Why Vacuum Degasser

After the invading of air into drilling mud, the density of mud will become lower and the viscosity will be higher, which will cause a inefficient operation in the downstream processes. The purpose of separating out the pure drilling fluid will not obtain. At last, the whole system will lost its value. Therefore, the existence of vacuum degasser is very necessary.

» How Vacuum Degasser Works

Vacuum degasser is mainly cosist of a treatment vessel, one chief motor, one vacumm pump and electrical controling parts. It works by creating lower pressure inside the top part of the vessel, so the mud will flow into the degassing tank fluently. Special separation baffle-design makes air or other gaseous impurities can be removed from the mud. The air is siphoned from the vessel after pressure is low enough to pump the gas out of the substance. A high-vacuum process environment is maintained for a variety of product testing and laboratory applications. This allows the user to analyze products or materials under a wide range of conditions and under predetermined atmospheric or environmental parameters. after processing through the degasser, the fluid will be treated without the interference of air in the next processes.

Function of the ZJ50 drilling fluid purification system

Recovering and purifying the drilling mud overflows from the well opening with high concentration
particles during the process of well drilling. The mud would be conveyed through the mud user self-provided pump to mud inlet tube group, the slurry more than 7 Microns would be cleared after processing. Thus to provide the required drilling fluid.

GN Solids Control have rich experience for drilling fluid purification solutions in all kinds of drilling. GN drilling fluid system is turnkey solution with first time commissioning service,training up of users engineer for operating the fluid system.
