With the implementation of oilfield acidizing technology and the entry into the middle and late stages of exploitation, it has become an urgent task to remove contaminants from the bottom hole and near-bottom formation of production wells and injection wells, restore or improve formation permeability, and increase crude oil production. AZ-CO corrosion inhibitor is mainly used to reduce acid corrosion to equipment, control acid-rock reaction rate, improve acidizing effect, prevent formation pollution and reduce implementation costs. Compared with previous corrosion inhibitor products on the market, its corrosion inhibition ability has made certain breakthroughs and has become a mature and stable product.

Packed in plastic drums or iron drums with a net content of (200.0±1.0) kg per drum.
1. Transportation: Prevent collisions during transportation to avoid package damage and leakage;
2. Storage: Should be stored in a cool and ventilated place, away from high temperatures, fire sources and strong oxidants.
1. The safe service life of the product is one year. Products beyond the service life need to be re-inspected for corrosion inhibition performance and can continue to be used only after passing the inspection;
2. It is recommended to wear protective gloves and goggles during use to avoid direct contact with skin and eyes. In case of accidental contact, please rinse immediately with plenty of water.
