MEASUREMENT TOOL AND METHOD OF USE

摘要

This invention relates to a measurement tool, and in particular to a 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 applicatio ns during the location and exploitation of oil and gas reserves. The measuremen t tool has a resilient pipe with a substantially uniform cross-section along i ts length, and the fluid is located 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 th e viscosity of the fluid within the pipe.
