Abstract: Hydrogen sulfide gradually appeared in the development and production process of an oil field in Bohai Sea,resulting in excessive hydrogen sulfide content in natural gas exported to a downstream natural gas receiving station,and the risk of aggravating equipment and pipeline corrosion,posing hidden dangers for safe production. After analyzing the production status of the oilfield,the source of hydrogen sulfide was determined,and targeted treatment measures were proposed to timely solve the problem of high hydrogen sulfide content in the oilfield production system.

Key words: natural gas, hydrogen sulfide treatment, sulfate reducing bacteria
