| titleOfInvention | Chemical blocking remover for polymer flooding injection well |
| abstract | The invention relates to a chemical blocking remover for a polymer flooding injection well, mainly solving the problem that the existing blocking remover adopting hydrogen peroxide and chlorine dioxide oxidant is poor in stability and unsafe. The chemical blocking remover consists of a former agent and a main agent, wherein the former agent consists of 15-20% of solid oxidant and 80-85% of water by weight; and the main agent consists of 7-10% of hydrochloric acid, 2-4% of nitric acid, 1-2% of glacial acetic acid, 2.0% of ammonium chloride, 1.0% of triethanolamine, 1.0-2.0% of corrosion inhibitor and 79.0-86.0% of water by weight. The chemical blocking remover for the polymer flooding injection well has the characteristics of good stability, easiness for storage and transportation, no toxicity, no odor, no pollution and safety. |
