The article focuses on the issues of constant and alternating electric field influence on physical – chemical properties of different types of water, on volume rate of fluid filtration from intensely clayey porous media and on the coefficient of oil recovery by water.
On the base of conducted experiments it was defined if traditional methods for oil extraction from low productive beds are not so effective then increasing of the coefficient value of oil recovery of hardly permeable reservoirs and particularly of high clayey reservois of Kirmaki suite can be reached by directed influence of external electric field with limited parameters of tension on secondary process of oil extraction by water electrolytes.
