Vacuum degasser in underbalanced drilling technology important role
During the drilling process, the gas carried by the drilling mud in the well not only affects the performance of the mud and poses a potential safety hazard, but also affects the service life of some solids control equipment. Therefore, a vacuum degasser is required to centrally remove the gas in the mud. In underbalanced drilling, the phenomenon of sticking frequently occurs when the well is deep, and the use of vacuum degasser can solve the sticking and sticking caused by the high density of drilling fluid.

The role of vacuum degasser in underbalanced drilling technology:
1. Conclusion It has been proved by field tests that the vacuum degasser is suitable for drilling fluid gas intrusion of various gases in conventional petroleum drilling and underbalanced special drilling operations, separating free and non-free gases in drilling fluid, and restoring the relative relative value of drilling fluid. density and viscosity.
2. It is used to deal with drilling fluid gas intrusion, with remarkable degassing effect, safe and reliable.
3. The vacuum degasser overcomes the disadvantage that the drilling fluid gas separator can only remove the free gas in the drilling fluid, but cannot remove the non-free gas, that is, the gas that invades the drilling fluid system.

1. During underbalanced drilling, the density of the drilling fluid is required to be relatively stable. After the drilling fluid gas intrusion occurs, the gas intrusion drilling fluid should be dealt with in time.
2. The special liquid-gas separator for underbalanced drilling is powerless to deal with the micro-bubbles invaded by the gas in the high-density and high-viscosity drilling fluid, and can only be treated by a vacuum degasser. Therefore, it is necessary to use a vacuum degasser to treat the gas-invaded drilling fluid to maintain the density of the drilling fluid to achieve normal drilling.
