摘　　要：以静态脱硫和杀菌性能评价为依据,通过脱硫主剂与杀菌主剂的筛选、优化及复配,最终研制出一种新型复合脱硫杀菌剂。实验结果表明,该药剂的表观硫容与杀菌效率分别达800 mg·L^(-1)和99%,且不具有金属腐蚀性,与原油及油田各类助剂的配伍性良好。现场应用结果表明,油井硫化氢质量浓度可由8000 mg·m^(-3)降至0,硫酸盐还原菌的数量由100000个·mL^(-1)降至10个·mL^(-1)以下,并能维持1~7 d,治理效果显著。上述结果可为油气田硫化氢的高效、低成本防治提供参考。A new type of composite desulfurization bactericide is developed in this study based on the evaluation of static desulfurization and bactericidal performance,and the screening,optimization and compounding of the main desulfurization and bactericidal agent,.The apparent sulfur capacity and bactericidal efficiency of the agent are as high as 800 mg·L^(-1) and 99%,respectively.It is not corrosive to metals so has good compatibility with crude oil and various additives in oil fields.Results from application to engineering fields showed that the concentration of hydrogen sulfide in oil wells was reduced from 8000 mg·m^(-3) to 0 mg·m^(-3),and the number of sulfate-reducing bacteria was reduced from 100000 mL^(-1) to less than 10 mL^(-1),which could be maintained for 1~7 days.Consequently,the agent has an excellent effect on the treatment of toxic and hazardous substances in the oil and gas development process.The results of this study are expected to provide references for efficient and low-cost prevention and control of hydrogen sulfide in oil and gas fields.
