FIELD: oil and gas industry.
SUBSTANCE: invention relates to the field of oil and gas production. Acid composition for chemical processing and filter cake removal of the well bore zone of the reservoir contains, wt%: 36 % aqueous solution of hydrochloric synthetic acid 91–94; complex reagent Reads 1–5 or ITPS-011 A 5–7; corrosion inhibitor of TH-IK-2 brand or Head KB 1–2.
EFFECT: increase in hydrocarbon production by increasing the efficiency and effectiveness of the processing of the near-wellbore zone of the reservoir and dispersion with simultaneous savings of material and labor resources.
