| Abstract: | In the paper, the corrosion and its mechanism about pipeline, pipe string, oil recovery equipment and cement sheathin wet H2S environment in oil gas field is analyzed. H2S content, pH and temperature and construction of material etc were the major factorsfor the corrosion. According to above factors, its anticorrosion measures is described respectively in order to minimize the damages. |
