Field practices shows that many wells that produce oil, gas and condensate in the final period watered. In this case, in the lift, in the pipeline, the capacitive system moves two-phase system, such as “water-oil”. Conducted a large literary analysis showed that insufficiently studied hydrodynamics of two-phase systems. In this paper, based on laboratory and field data, proposed a new movement model emulsion systems. It was proposed a method for determining the basic indicators such systems. On the basis of this method, it was receipted a formula for determining the dynamic viscosity of such systems.
