n: total pressure measured from an absolute vacuum. It equals the sum of the gauge pressure and the atmospheric pressure. Expressed in pounds per square inch.

the reading of gauge pressure plus the atmospheric pressure.

n: The rarefication in the vacuum degasser when the volume of drilling fluid is balanced.

n: a tank of a shape commonly used in the petroleum industry. It is not constructed to withstand any appreciable pressure or vacuum in the vapour space;it may, therefore, be gauged directly through an open hatch.

n: The steel container achieving the separation of gas and liquid in vacuum degasser.

n: when stop the pump ,because the fluid density in the pipe is hihger than that in the hole annulus ,the fluid surface in the pipe desents leading the appearance of vacuum

n: a conductor of electric current as it leaves or enters a medium such as an electrolyte, a gas, or a vacuum.

n: the erratic impact of a pump plunger against a fluid when the pump is operating with a partial vacuum in the cylinder, with gas trapped in the cylinder, or with the well pump off.

or rod pound – a beam lift term where the pump is filled with gas from pump-off or too fast of an operating speed (rod speed).

n: a device employing a venturi nozzle through which a highpressure stream creates a lower pressure or a vacuum into which the gas to be compressed flows. The gas is discharged from the nozzle with the expanded highpressure medium.

n: synthesized the working theory of vacuum degasser and atm degasser, the degasser is designed to meet the low density and visous drilling fluid.

n: the vacuum of de-gasser that the vacuum degasser shuts off the pass in and out valve.
