 Abstract
This paper presents the experimental researches of corrosion phenomena in field waters and relates to the protection of steels surface using ecological compound (Na-lignosulphonate) as corrosion inhibitor.
The corrosion rate of steels in field water inhibited by Na-lignosulphonate was determined by conventional weight loss measurements.

 Rezumat
Lucrarea prezintă cercetări experimentale ale fenomenelor de coroziune în ape de zăcământ şi respectiv protecţia anticorosivă a suprafeţei oţelurilor folosind ca inhibitor de coroziune un compus ecologic (Na-lignosulfonat).
Viteza de coroziune a oţelurilor în ape de zăcământ cu inhibitor Na-lignosulfonat a fost determinată prin măsurători gravimetrice.
