Causes and Remedial Measures of Hydrogen Sulfide Generation in Dongsheng Oilfield Area
Hydrogen sulfide poses a significant safety hazard in the oil and gas development process,causing severe damage to downhole tools and surface equipment and posing a serious threat to the health of on-site construction workers.The Dongsheng Oilfield area has diverse reservoir types and complex geological conditions.In response to the occurrence of high concentrations of hydrogen sulfide in the area,the article analyzes the mechanisms of hydrogen sulfide generation primarily based on three factors:thermal chemical reduction reactions in formation,secondary reactions in wellbore fluids,and biological origins.By tracking production dynamics and combining field application technologies,the article proposes short-term emergency and long-term comprehensive treatment strategies.Differentiated measures for hydrogen sulfide monitoring,selection of desulfurizing agents at the production end,selection of bactericides at the injection end,and optimization of dosing methods are proposed based on different situations.The on-site application has achieved good results,effectively containing the spread of hydrogen sulfide,thereby effectively eliminating safety hazards in the Dongsheng Oilfield area.Furthermore,it provides a basis and guidance for subsequent hydrogen sulfide management technologies.
