Downhole viscosity measurement platform using tuning …
WebJun 4, 2014 · The sensor was designed to be both highly accurate and sufficiently robust to withstand the temperature, pressure and drilling vibrations encountered in downhole logging. Viscosity is measured to within 0.1 cP for fluids less than 1 cP and 10% for all viscosities above 1 cP.. Density measurements are accurate to better than 0.01 g/cc. WebFig. 5. Top: Exploded view of sensor ball highlighting its main components: battery, circuit board, and magnetic release mechanism. Bottom: Sensor ball after fabrication and integration of electronic boards. The inside of the ball is potted with an epoxy resin to maintain pressure compensation with the high pressures of the outside environment. - … 5陰連
A New Sensor for Viscosity and Fluid Density Measurement for …
WebBy monitoring the frequency and the decay rate during ring-down, transient changes in density and viscosity can be obtained within milliseconds in liquids. The compact measurement scheme implemented here allows us to use the tuning fork as a flow detection and fluid characterization sensor in an untethered well-logging tool for rapid … WebOct 1, 2024 · That sensor can resolve the viscosity at a downhole location in the ranges from 0.2 mPas to 300 mPas with uncertainties stated in the range of 10 %. Another device for downhole viscosity measurements which operates autonomously without wire-line connection is proposed by a tuning fork device [23]. WebJun 1, 2011 · Because the fluid density and viscosity measurements are to be made in the high-pressure, high-temperature downhole environment, a patented tuning fork assembly was created [14]. This assembly includes a high-pressure feed-through with two electrical leads running through it and attaching to the electrical connections of the two tuning fork ... 5陵
