Vacuum Degasser Improves Treatment Efficiency of Gas-Invaded Drilling Fluid

In oilfield drilling operations, a large amount of gas and bubbles contained in gas-invaded drilling fluid will damage the stability of mud performance, shorten the service life of equipment, and even cause potential safety hazards. As professional oilfield drilling degassing device, the vacuum degasser from TR Solids Control can efficiently remove gas from gas-invaded drilling fluid, significantly improve treatment efficiency and quality, and ensure the smooth progress of drilling operations.

The vacuum degasser is composed of suction pipe, vacuum tank, main motor, separation rotor assembly, water ring vacuum pump, gas-water separator and other components, adopting scientific structural design. Its working principle is as follows: by using the suction effect of the vacuum pump,  negative pressure zone is created inside the vacuum tank. Under the action of atmospheric pressure, the mud enters the hollow shaft of the rotor through the suction pipe. Then the main motor drives the rotor to rotate at high speed, throwing the gas-invaded mud from the suction pipe to the tank wall. Due to the collision and the function of the separation wheel, the drilling fluid is separated into thin layer, the bubbles immersed in the mud are broken, and the gas is released. Through the suction of vacuum pump and the separation of gas-water separator, the gas is discharged to safe area through the exhaust pipe of the separator, and the mud is discharged out of tank by impeller.

During drilling operations, the gas carried by the drilling fluid from the well kick affects the mud performance. The vacuum degasser can remove the small entrained bubbles remaining in the mud from the mud/gas separator.

TR Solids Control vacuum degasser can be flexibly adapted to various mud purification systems. It is usually installed downstream of mud/gas separators, shale shakers and mud cleaners. It can quickly restore mud density, stabilize core performance, and can also be used as high-power agitator, adapting to various types of mud circulation and purification systems. It is the preferred equipment for gas-invaded drilling fluid treatment.

Core Advantages of TR Solids Control Vacuum Degasser

1. Reasonable structural design can effectively separate gas and fluid, filter out impurities, and ensure the exhaust pipe is always unobstructed.

2. Belt drive design avoids the complexity of reduction gears and realizes long-term trouble-free operation.

3. The water ring vacuum pump operates at constant temperature, suitable for flammable and explosive scenarios.

4. Degassing efficiency is as high as 95% or more.

5. Built-in gas-water separator prevents simultaneous gas-liquid discharge and supplies water to the vacuum pump to save water.

TR Solids Control vacuum degasser has four major series of models: TRZCQ240, TRZCQ270, TRZCQ300 and TRZCQ360. The maximum processing capacity can reach 360 m³/h, and the degassing efficiency is stably above 95%. It can meet the treatment needs of gas-invaded drilling fluid at different depths in oilfield drilling, providing reliable guarantee for oilfield drilling operations.
