Oilfield Reinjectionwater Corrosion Inhibitor
The product is a kind ofwater solubility film formation corrosion inhibitor, which is composed ofhome-grown composite pyridine quaternary ammonium salt as main ingredients,other synergist and surfactant. Non-polar groups in the molecule can effectivelyprevent CO2、H2S corrosion medium from metallocal corrosion. And while the hydrophilic groups are firmly adsorbed on themetal surface and form a dense protective film. So it can keep a long time formetal against corrosion. It has a good protection, especially for hydrogenembrittlement and pitting which are produced by high concentrations of CO2system. Also, it has a good anti-corrosion for H2S local corrosion.The product has good heat stability and chemical stability.
Obviously corrosioninhibition properties effect on CO2、H2S andresistance to high salinity.
It is applicablefor protecting oilfield water injecting pipeline corrosion and equipmentcorrosion. It has a good protection function for not more that 20% CO2、H2S and other acid gases, as well as not more than 200000 mg/Lsalinity saltwater corrosion environment.
Calculated byliquid production capacity, generally add 50ppm. Appropriately increase amount forthe severe corrosion area. The corrosion rate can reach more than 80%. As forthe high salinity area, dilute by tap water to 10-20%, and then add it.
