The product is a kind of film formation corrosion inhibitor, which is composed of home-grown composite pyridine quaternary ammonium salt as main ingredients, other synergist and surfactant. It can be applicable for high salinity saltwater system anti-corrosion in the oilfield injection CO2 displacing oil technical process. By the process, high partial CO2 control carbon steel metal corrosion, and it has a protection for carbon steel metal corrosion caused by oil well produced water with high CO2 and chloride ion, carbonate ion high salinity. It has an excellent comprehensive performance and good protective effect in all of oil, gas, and water phase. Meanwhile, it can be able to inhibit corrosion and hydrogen embrittlement caused by H2S. And also, it has a good compatibility with other oilfield chemistry agent.

Technical Indicators of SL-CR-CO2

Good corrosion inhibition properties effect on series of high partial pressure CO2.

It is applicable for corrosion control under high partial pressure CO2 and high salinity saltwater system corrosion environment in the oilfield CO2 displacing oil technical process, as well as corrosion control for oilfield wastewater system with certain partial CO2.

The concentration of corrosion inhibitor addition is 100mg/Lin the injection CO2 displacing oil technical process. But in the oil well produced water system, the concentration of CO2 corrosion inhibitor addition is 500 mg/L. it has a better effect with cooperatively using deoxidant in closed aerobic system. Dilute corrosion inhibitor 1 ~ 2 times by tap water and then use it.

The product is packaged with 200L plastic drum, and net weight is 200 kg per drum. If customers need special packaging, we can pack it as customer’s request. The product should be stored in a ventilated, cool, dry storeroom and should be away from the fire. Product is valid for two years.
