n: a scale for measuring small increases or decreases in pressure. usually in conjunction with a manometer, a U-tube containing mercury. Pressure on one side of the U-tube causes the mercury to move upward on the other side. The movement is measured in inches or millimetres. See manometer.

n: a scale for measuring small increases or decreases in pressure, usually in conjunction with a manometer, a U-tube containing water. Pressure on one side of the U-tube causes the water to move upward on the other side. The movement is measured in inches or milli- metres. See manometer.

n: a U-shaped tube. v: to cause fluids to flow in a U-tube without adding an outside force. For example, heavy mud in the drill stem will force light mud in the annulus to flow.

a fluid flow path that has a low spot. In a well, the U-tube is represented by the tubing and the annulus with the bottom of tubing as the low spot. Where two different density fluids are involved, the effect is that the lower density fluid will be pushed

n: A kind of ways be used to solve the differential pressure sticking,which use the u-tube principle to decline the fluid level of hole.

n: We can think the circular and the inner of well as the two side of u-tube.Their affection on the bottom hole must be equit.

n: the action of fluids flowing in a U-tube (as heavy mud forcing lighter mud down the drill stem and up the annulus).
