Physical aspects of reagent and pulse influence on capillary porous saturated media

Summary form only given. Physical features and principles of changing filtering characteristics of mountainous porous rocks under influence of dual action of electric discharge and reagent for the increasing of total amount of oil pumped from the oil holes have been studied. Such an influence changes features of the rocks. It has been determined that application of water-soluble multifunctional compositions of surface-active substances as a working medium for a high-voltage electric discharge gives an opportunity to greatly increase porosity and penetrability of carbonates and sandstones. The separate roles of reagent influence and of electric discharge influence have been determined. Complex influence of both this factors on the porous rocks provides a better effect than the sum of effects of separate influences, and this effect can be increased many times by increasing the pulse pressure amplitude The effect of the dual processing is due to the increasing of wash off capability of reagents with their nonstationary filtration in pulse pressure.
