【 摘 要 】

The presence of sulfides in reservoirs and produced fluids is a function of microbial, electrochemical, and geochemical processes. Problems presented by sulfides include environmental compliance, toxicity, corrosion, reduced well performance, offensive odor, reduced monetary value of products, and increased operating costs. Technologies for the removal and control of sulfides include the use of biocides, scavenging agents, corrosion inhibitors, Claus reactors, amine plants, etc. Problems with these technologies include: ineffectiveness, use of toxic chemicals, cost, and generation of toxic wastes requiring disposal.[First Paragraph]
