Experimental Study on Factors Affecting the Generation of Ferrous Sulfide

Abstract:

Now steam stimulation gradually become one of the major thermal recovery methods, and hydrogen sulfide appears in the well casing. With the increase of the thermal recovery time and the application of SAGD technology, the number of wells containing hydrogen sulfide increased, and concentration of hydrogen sulfide are also rising,Producing corrosion products - ferrous sulfide. Ferrous sulfide has pyrophoric. When ferrous sulfide in contact with oxygen in the air can cause spontaneous combustion at room temperature. In order to avoid the occurrence of spontaneous combustion of ferrous sulfide we had an in-depth study of the spontaneous combustion of ferrous sulfide. Through laboratory tests we found the following points. At room temperature,sulfurization reaction of H₂S gas and iron oxides occurs more easily in a dry environment. Temperature, H₂S humidity, various iron oxides,have important effects on the generation of iron sulfide.
