In the process of sour gas reservoir development, hydrogen sulfide usually causes corrosions and damages in oil line, casing pipe and drilling apparatus. Due to the complicated situation and lots of corrosion factors, various corrosions occur in the well. Based on the real data from several sour gas reservoirs in China, the basic characteristics, modes and main influential factors of tube's corrosion are expounded in this paper, which offers the dependable grounds to prevent the tube from corrosion.
