Summary:
   It is amphoteric surface active agent with good dispersivity in the water and good inhibition to corrosion which caused by high mineralized oilfield sewage of carbon dioxide and hydrogen sulfide. It controls corrosion of watering pipeline and equipment with oilfield water quality, antioxidant and disinfectant in secondary mining. It has extremely good clean effect to the metal wth wide pH value, non-toxic and no smell. It uses for secondary mining in the oilfield flood pipeline and equipment's anticorrosion, as well as cooling water cycle pipe-line equipment.
