Measurement tool and method of use

摘要

MEASUREMENT TOOL AND METHOD OF USE This invention relates to a measurement tool, and in particular to a 5 measurement tool for use in determining the density and/or viscosity of a stationary or moving fluid. The measurement tool has been designed for use in borehole applications during the location and exploitation of oil and gas reserves. The measurement tool has a resilient pipe with a substantially uniform cross-section along its length, and the fluid is located to within the pipe. The pipe carries an exciter which is connected to a signal generator, the exciter and signal generator being adapted to impart transverse and/or rotational oscillations to the pipe. Measuring the frequency of the oscillations can be used to determine the density and/or the viscosity of the fluid within the pipe. (Fig.1) co <0a
