n: see drift angle.

n: The angle between the tangent of borehole axis and vertical line, measured by inclinometer.

n: liquid chemical derived from benzene or from benzene and ammonia. It is used as a solvent and in the organic synthesis of other substances.

n: C6H7N, colourless and oil like liquid, tang and toxic. Usually used in measuring content of aromatic hydrocarbon in drilling fluid operation.

n: The method assuming that borehole axis of two adjoining measured points is a polygonal line. The length of one part of polygonal line is equal to another part. The deviation angle and azimuth of upper part is same with upper measured point and the deviati

n: When the pressure suffered by inferior drill column reach to critical value, it deviates the vertical axis and forms a tangency point with borehole face.

n: If bit load continues increasing after buckling of first order, bending shape will change piecemeal and tangency point will move downward.

n: a pump with an impeller An electric submersible pump is a centrifugal pump.

n: A machine for moving fluid by spinning it using a rotating impeller in a pump casing with a central inlet and a tangential outlet. The path of the fluid is an increasing spiral from the inlet at the center to the outlet, tangent to the annulus. In the ann

pump with an impeller or rotor that spins in a housing and the drag forces on the fluids cause them to flow.

n: 1. a low-pressure area, around which wind flow is counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The term is sometimes used to describe storms occurring in the atmosphere;in the Indian Ocean it is used to designate a tropical cyclone. 2. a device for the separation of various particles from a drilling fluid, most commonly used as a desander. The fluid is pumped tangentially into a cone, and the fluid rotation provides enough centrifugal force to separate particles by mass weight.

n: A device for the separation of solid particles from a drilling fluid. The most common cyclones used for solids separation are a desander or desilter. In a cyclone, fluid is pumped tangentially into a cone, and the fluid rotation provides enough centrifuga

a device that separates cuttings by centrifugal motion of the fluids.

n: part of a diaphragm meter that regulates the length of the diaphragm stroke;used to adjust the volumetric displacement.

n: a kind of solids control technology being in phase of experiment ,namely setting an inverse swirler making the fluid in the drill pipe flow into the container in a tangent line

n: in a two-diaphragm. fourchamber diaphragm displacement meter. the link- age that transfers oscillating motion from the flag rods to turn a tangent and crank assembly.
