| titleOfInvention | Acidic composition for treatment of formation bottom-hole zone |
| abstract | FIELD: oil and gas industry.SUBSTANCE: invention relates to the oil-producing industry. Acidic composition for treatment of the bottomhole formation zone includes, wt%: hydrochloric acid 5.0–15.0; acetic acid 3.0–5.0; ammonium bifluoride 2.0–5.0; corrosion inhibitor and water repellent – surface-active complex composition SCC 1.0–5.0; nitrilotrimethylphosphonic acid NTP 0.05–0.25; N,N-diacetoglutamic acid 0.5–2.5; fresh water – balance. NTP and GLDA are taken at weight ratio of 1:10 respectively.EFFECT: wider range of products for acid treatment of the bottomhole formation zone, including that represented by terrigenous reservoirs with carbonate inclusions, which increase quality of acidic treatments due to stabilization of ions of alkali-earth metals and Fe (III) by transferring them to stable water-soluble complexes.1 cl, 2 tbl, 1 ex |
