Fluid Flow Regimes Analysis on Drilling Fluid Circulation for Cuttings Lifting in Vertical Drilling Oil Wells

Fluid Flow during the circulation of drilling fluid is an important parameter that affects process successful lifting cuttings activities. Researcher analyzed regimes flow in vertical wells through analysis velocity calculation pipeline at conditions Drillpipe (v DP) 21.11791 fps and drill collar DC) 42.98293 fps, annulus between Casing Drill pipe 1.14993 1.373781 Open Hole pipe, 1.594947 Collar, critical annulus, Reynolds number 15986.36, inside Collar 22807.21, annular 2847.435, 3037.264, 2679.938 which cutting drops when all three zones 0.14914 fps. The results occurs are found there a turbulent laminar occurs. In addition, comparison greater than descent show can be lifted by successfully. This indicates successful.
