COUETTE DEVICE AND METHOD TO STUDY SOLIDS DEPOSITION FROM FLOWING FLUIDS

摘要

THERE IS DISCLOSE A METHOD OF MEASURING AN EMULSION OR SOLIDS DEPOSITION IN A FLUID SAMPLE, COMPRISING CHARGING THE SAMPLE TO A COUETTE DEVICE; SUBJECTING THE SAMPLE IN THE COUETTE DEVICE TO A PRESSURE, A TEMPERATURE , AND A SHEAR COMPARABLE TO FIELD CONDITIONS; CHANGING AT LEAST ONE OF THE PRESSURE, TEMPERATURE, COMPOSITION, OR SHEAR OF THE SAMPLE; AND QUANTIFYING THE TYPE AND AMOUNT OF SOLIDS DEPOSITED ON THE INTERIOR WALLS OF THE COUETTE DEVICE. THERE IS ALSO DISCLOSE COUETTE DEVICES WHICH CAN BE USED IN THE METHOD.FIG.1
