| Research Abstract |
In this study, the principle of the viscosity measurements for high pressure and high temperature has been presented by using Hall element that measures the falling time of the small magnetic object in the measuring fluid cell to evaluate fluid viscosity. A prototype of the device to measure fluid viscosity was constructed and its calibration tests were done to investigate the accuracy of viscosity measurements. It was applied to viscosity measurements of heavy oils in various conditions related to EOR projects. Particular crude oil samples, such as heavy oil dissolving CO2 gas under high pressure, foamy oil including CO2 micro-bubbles generated by depressurizing and heavy oil emulsion made by injecting steam, were measured and their viscosity characteristics were studied experimentally. Based on these results, it has been clarified that the present measurement method can be applied to measure the viscosity of various crude oils.
