الحصول على السعرMay 12, 2016 · Pressure differential is difference between atmospheric pressure between production area and its surroundings. It is measured in pascal using magnehelic pressure gauge. According to WHO guidelines on HVAC system, 1015 pascals of differential pressure is maintained between manufacturing and surrounding areas.
الحصول على السعرDuring the stimulation there is high pressure exerted on the top side of the plug, with lower pressures on the bottom of the plug. This differential in pressure dictates how the plug must be designed to withstand the forces exerted. As you can see below, the pressure from the frac is exerted on the ball, and the mandrel above the element.
