FIELD: oil and gas industry. ^ SUBSTANCE: in well bore zone treatment method involving determination of composition of formation rock in the treated zone by means of hydrocarbon-oxygen logging - HOL, and at carbonate content in formation rock of more than 5%, and clay - less than 10%, irrespective of quartz content, as treatment agent there used is water solution of chlorhydric acid with concentration of 10-18% with additions of Neftenol-K in quantity of 2-5% and IKU-118 in quantity of 0.10-0.30% of volume of water solution of chlorhydric acid. Invention has been developed in dependent claims. ^ EFFECT: improving the efficiency of the method due to possible quick acquisition of information on the state of well bore zone, up to its composition, and directed action on the treated medium. ^ 8 cl, 1 ex |
