Experimental provision.
Background technique
East China onshore oil field has largely entered development late stage at present, most oil well composite water cuts oneself be more than
85%, some oil wells have reached 95%, and the method cost with original oil well produced liquid conveying crude oil mixed with hot water is very high, energy
It consumes huge.Oil gas water three phase flowing is widely present in oil and natural gas recovery process, each not phase of the physical property of oil gas water three phase
Together, together mixed flow when there is apparent phase interfaces.Oil gas aqueous mixtures along collector tubing from well head to turn
The flowing of petrol station belongs to Three-phase Flow, and different hydraulic models is corresponded under different flow patterns.Oily mixing wastewater with air Multiphase Flow and
Gas liquid two-phase flow the difference is that, it is weak that momentum between water-oil phase transmits stronger lift effect, shows that free energy is smaller.Cause
This, Multiphase Flow is more much more complex than single-phase flow, and the flow pattern of formation is also much more complex.Up to now the stream of oil gas water three phase flowing
Type, pressure drop feature scholars could not also unify its definition, not propose general flow pattern, flow pattern expression formula and pressure drop mould
Type.Therefore, the flowing law of research oil-gas-water three-phase flow in the duct has great importance.
