摘　　要：针对渤海某油田上下游流程中存在的硫化氢问题,分析了硫化氢成因,展示了对上下游硫化氢治理采取的不同治理措施及效果。具体措施为:在上游.通过在注水井中加注生物抑菌剂,刺激地层中的NRB生长,与SRB争夺营养源,抑制SRB的繁殖.从而降低实验区块的硫化氢含量;下游处理厂在原油沉降罐、调储罐、气浮选罐各排气口设置活性炭脱硫塔,对尾气充分脱硫后再外排.使厂区环境得到明显改善。This paper focused on H_2S problem in Bohai Oilfield.analyzed the cause of H_2S and researched the control measures and effects.The main control measures included adding biological antibacterial agents through the injection well in the upstream,which could stimulate NRB for growth and compete for nutrients to inhibit SRB's growth and reduce H_2S content of the experimental area.And in downstream,activated carbon desulfurization towers were built for desulfuration at the exhaust ports of crude oil settling tank,storage tank and air-floating tank.Through activated carbon desulfurization towers,the factory environment was significantly improved.
