Vacuum degasser is widely used in oilfield drilling solids control system, and vacuum degasser is supposed to be used in the following circumstance. Gases are entrained in drilling fluids from the wellbore during normal drilling operation as well as during “kick” or well control situations ,these gases may bring safety hazards and create operational problems, in case of the presence of hazardous gases, it is desirable to localize the point where gas is released from the mud by installing a vacuum degasser.
There are some advantages of vacuum degasser. Self-contained unit without need for centrifugal pump to feed drilling mud. Eliminate corrosion and reduce reparation and maintenance costs. Short footprint, can be installed in smaller spaces. Degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter.
Here are several points that must be put into consideration.
Processing capacity of drilling mud system. Vacuum is generally set after the drilling mud shale shaker and before the centrifugal pumps. Because when the drilling mud is with toxic gas, pump will be destroyed by the gas and caused gas discharge and even may lead to serious noise and vibration. Vacuum degasser is functioned as two points, keep steady characteristic of drilling mud and make sure the normal processing of cyclone. In deep drilling, gas well drilling, vacuum degasser must be assembled. Vacuum degasser plays role in mixing and vacuum pumping. In addition, vacuum pump also should be matched properly with the vacuum degasser. If it is smaller or bigger than what the degasser processes, the degasser will not normally process drilling mud and drilling mud circulation efficiency is sure to be lowered. At last, daily maintenance of the vacuum should not be ignored. You know, it really works if you are hard and careful enough to do this job.
