| titleOfInvention | A kind of multi-hydrolysis micellar acid blocking agent and blocking removal process |
| abstract | A polyhydrohydrolytic micellar acid blocking agent and blocking removal process, based on 100% of the composition mass, 0-30% of alcohols, 0-10% of polyethylene glycol, 1-40% of organic solvents , 0-20% alkyl sulfonate, 0-20% alkyl sulfobetaine, 0-20% polyoxyethylene ether, 0-20% sorbitan monoester, 0-20 % ammonium fluoride, 0-20% fluoboric acid, 0-20% organic acid, 0-20% organic phosphonate, 0.5-2% acidification corrosion inhibitor, and the rest is industrial hydrochloric acid mixed at high temperature and high speed before adding Stir other treatment agents evenly; the on-site plugging removal process is sand washing, injecting pre-liquid, injecting pre-acid, and then injecting high-concentration polyhydrolyzed micellar acid deblocking agent solution and low-concentration polyhydrolyzed micellar acid solution in sequence. The plugging agent solution is injected into the replacement fluid, and finally the oil pipe is filled with injected water, and after the reaction, the water injection is resumed; the invention has a high success rate of plugging removal. |
