Mechanisms and capacity of high-pressure soaking after ...

High-pressure soaking has a significant impact on oil production through the mechanisms of imbibition and elasticity, both of which have considerable contributions. Imbibition works at the soaking stage, and elasticity works at the depressurizing stage. High-pressure soaking could make more water enter the matrix even in mixed-wet rocks.

How does a pressure washer work? - Explain that Stuff

Parts of a pressure water. A pressure washer is less sophisticated than it sounds. It's really just a water pump powered by an electric motor.The washer takes in ordinary water from a faucet (that's a tap to you folks in the UK), the pump accelerates the water to high pressure, and then squirts it from a hose at speed through a trigger gun.

The Study of Tubing Vibration Mechanism in High Pressure ...

Deep gas wells and gas fields have the characteristics of high pressure. The vibration of the tubing string during the production of gas wells causes the string to be subjected to severe stress and even dynamic fatigue failure. Therefore, this article is based on the dynamic finite element theory, aiming at the characteristics of large-size tubing strings in deep gas wells.

Physiology, Arterial Pressure Regulation - StatPearls ...

The role of arterial pressure regulation is to maintain a high enough pressure that allows for proper perfusion of body tissue and organs; but not so high as to cause bodily harm. When the body enters a state of acute hypotension, the baroreflex function attempts to return arterial pressure to its stable state to allow continuous perfusion. [9]

Abstract. A series of Al-xCe (x = 2, 4, 6, 8, 10 wt%) and Al–8Ce-yMg (y = 0, 0.10, 0.25, 0.50, 0.75 wt%) alloys were prepared by high-pressure die casting. The introduced cerium element promoted the nucleation of α-Al grains. Al 11 Ce 3 phase served as the heterogeneous nucleation substrate of α-Al due to the small lattice mismatch of 6.72%.
