Abstract:Displacements of oil-based and water-based fluids, corresponding to miscible and immiscible fluids, exist widely in well cementing processes in the oil & gas industry. In this paper, we experimentally investigate the density-unstable miscible and immiscible displacement flows in an axially rotating pipe. The density of displacing fluid is larger than that of the displaced fluid (๐ ฬ๐ป > ๐ ฬ๐ฟ). In our experiments, the density difference (quantified via ๐ด๐ก = 0.041 ), the viscosity ratio ( ๐ = 0.22 ), and t… Show more
