| مستخلص: | The example reservoir rocks lower Permian sediments of Hnidyntsivske oilfield Dnieper-Donets basin revealed that the effect of polymer-clay mud leads to a reduction the phase permeability to 4.2 times. There was testing the effectiveness of 14% hydrochloric acid by the proposed method. We found that the most effective is the processing of reservoir rocks, where the pore volume was forced out of filtrate and free oil. During which phase permeability increases more than 13 times compared with the initial. The described method takes into account the lithologic and petrophysical features of reservoir rocks and can be used successfully in other geological and technical conditions of occurrence of productive deposits. It was established that the presence mud filtrate and hydrocarbons in pore volume does not contribute to the effectiveness of hydrochloric acid treatments in the bottomhole formation zone.
