Abstract
Last years the interest to energetically influence on material for the reason change their characteristic remains stabiles high.The calculation of the oil material's individual particularities show it is possible to change structure in necessary direction using shock influence without observable external energy expenses.As such influence, for controlling structure of material used electro-hydroimpulse influence on the oil.It is can be reached easy to increase of regulate nuclear structure using this effect.Results of properties study of the heavy oil from the Karazhanbas field, which was subjected to electro-hydro-pulse discharge for the purpose of demetallization, are presented.
