Abstract
A spark approach is used for description of the discharge dynamics in water and oil emulsions. The approximate method for calculation of the spark constant which is the factor between plasma internal energy and conductivity is grounded on the base of the experimentally registered electric discharge volt-ampere characteristics in the emulsions. The influence the degree of oil saturation with water and the initial specific conductivity of water in the stratum upon the spark constant is shown. The results obtained will be useful for numerical simulation of the transient electric and hydrodynamic processes of the phenomenon under investi- gation.
