n: a flow meter used to determine the rate of flow and employing a venturi tube as the primary element for creating differential pressures in flowing gases or liquids. Compare orifice meter.

n: an electrical measuring instrument that verifies the presence or absence of current or emf in a circuit. A compass needle and a dashboard ammeter are verification indicators.

n: The typical vermiculite is two to one type tri-octahedral banding silicate,which can as the the block agent of gaping leakage zone.

n: The projecting length of well depth on the vertical line is vertical depth ;measured depth is the true length of a well.

n: The crack that vertical to horizen plane in formation.

n: a change in the configuration of a pipeline whereby the pipe is curved from the horizontal to a 9()!1 vertical run, then curved 902 to a horizontal run, curved again to a 902 vertical, and then curved 90Q back to horizontal. The effect is to create turbulence in the fluid flow and distribute the S&W evenly in the flowing stream.

n: The vertical profile of wellbore of directional well,which can display the measured depth ,vertical depth ,deviation angle and horizontal displacement.

n: The projection of virtual borehole axis on the the vertical plane of designed azimuth line.

n: a pre-established location in the vertical plane along the tank shell couesponding to a given horizontal station. Compare horizontal station.

n: (VSM) an Hshaped device that supports a pipeline above the ground. Vertical support members are used in parts of the world where frozen earth prevents normal burial of the line. See lowering-up.
