| titleOfInvention | Scale remover for oil well and preparation method thereof |
| abstract | The invention relates to a scale remover for an oil well and a preparation method thereof, belonging to the technical field of cleaning agents for oil exploitation equipment. The invention adopts the alkaline scale remover prepared by using the chelating agent of three-dimensional envelope type, namely imino disuccinic acid tetrasodium (IDS), diethylenetriamine pentaacetic acid (DTPA), amino trimethylene phosphonic Acid (ATMP), ethylene diamine tetramethylene sodium phosphonate and polymaleic acid, has strong chelating ability, has better removal effect on inorganic scales such as carbonate scale, sulfate scale and the like by complexing the inorganic scales generated in an oil field through multi-stage ionization, has small corrosivity on oil exploitation equipment, and prolongs the pump inspection period of an oil well. |
