摘要：The flow of oil-water in pipes commonly occurs in
oil and petroleum industries and is a challenging issue. Clear
understanding of the frictional pressure drop (FPD) of oilwater
flows in pipes is important for determining size of pumps
and pipelines in transportation of oils.
An experimental study investigation conducted for
measurement of pressure drop of oil (D130)-water two-phase
flows in 6 inch diameter horizontal stainless steel annulus pipe
at different flow conditions. Two-phase large scale horizontal
flow loop was used to acquire data for different water cuts and
fluid mixture (oil-water) flow rates. Experiments were carried
out for different water cuts (WC) ranging from 0-100% in
steps of 20%. The oil-water flow rates were varied from 2000
to 12000 barrels-per-day (BPD) in steps of 2000. Exxsol
mineral oil (D130) and potable water have been used as
working fluids. In order to simulate field conditions, the range
of liquid flow rates used matches the range of actual flow rates
in oil wells. The FPD has been found to decrease initially (for
all flow rates) from WC=0% to WC=20 %. Further increase in
WC, causes FPD to increase from WC=20% to WC=40%. This
is due to phase inversion. For a given WC=40, for increase in
BPD from 6000 to 8000, increase in FPD is about 34%. The
outcomes of the study will be helpful in mitigating multi-phase
flow problems in oil industries.
