Drilling fluids vacuum degasser is widely used on drilling site for removal of gas entrained in the drilling mud after treatment of shale shaker in the drilling fluids system. So drilling fluids vacuum degasser plays a significant role in the oil field drilling fluids system.
As We Know there are several serious harms can be caused by gas-cut drilling mud
1. The density of drilling fluids will be reduced. After the density of drilling fluids is reduced, if the pressure of net liquid column of drilling mud in the well is lower than the formation pressure, well kick or blowout may occur.
2.Suction of sand pump, filling pump and drilling pump used in the drilling fluids system will be poor, even abnormal operation will occur, causing equipment vibration.
3. Some poisonous gas (such as H2S) will escape from the fluids, which may leads to poisoning to operators on the drilling site.
4.It may cause fire on the drilling site.
5. After gas-cut, the viscosity of drilling mud will increase, reducing the drilling speed of drilling machine. Therefore, the gas cut into the drilling fluids must be removed. Generally, mechanical degasser is selected.
The basic principles for mechanical degassing of drilling fluids vacuum degasser
1. Drilling fluids vacuum degasser make the air bubbles rapidly rise to the liquid surface. The parameters are diameter of air bubble, density of air bubble, density of drilling mud and dynamic viscosity of drilling fluids.
2. Drilling fluids vacuum degasser make the liquid layer become thin. After being treated by shale shaker, the drilling mud enters the mud tank. The mud tank is deep, which is unfavorable for the air bubbles rapidly rise to the liquid surface. The vacuum degasser can create conditions to make liquid layer become thin, to help the air bubbles to rapidly rise to the liquid surface.
3. Facilitate expansion of air bubbles. Place the gas-cut drilling mud under normal pressure into vacuum condition to reduce pressure, volume of the air bubbles will increase. The higher the vacuum degree is, the larger the volume of air bubbles will be.
4. Use centrifugal field to accelerate the movement of air bubbles.
