چکیده انگلیسی
Solids transport in multiphase systems is one of the issues under the umbrella of “flow assurance”. But unlike issues such as waxes and hydrates, solids transport has received relatively little interest to date. The overall aim of this research was to investigate the fluid viscosity effects on sand particle transport characteristics in pipelines. Investigations were conducted using a 3-in. test facility for oil and a 4-in. flow loop for water and CMC experiments. Three oil viscosities were used including 105Â cP, 200Â cP and 340Â cP. The sand used had a density of 2650Â kg/m3 and a median diameter of 0.2Â mm. The sand loadings were 50Â lb/1000Â bbl and 200Â lb/1000Â bbl. Based on the King et al. (2000) sand minimum transport condition definition, the sand transport velocity for water, CMC solutions and oil (105Â cP, 200Â cP and 340Â cP) were determined by visual observation and camera. The observed sand/oil flow regimes were compared. For oil/sand tests, it was observed that the dominant regime when approaching the critical sand transport velocity was the sliding sand bed, sand dunes were notably absent. However, for water and 7Â cP CMC solution, sand dunes and sliding sand bed regimes were observed when approaching the sand transport velocity. For 20Â cP CMC solution, it was observed that the sand particles in the region between the main dunes were very active compared to those within the dunes.
