【摘要】 针对渤海P油田注水细菌滋生情况,采用细菌绝迹稀释法考察了不同类型的杀菌剂的杀菌效果,室内试验表明,季磷盐与双季铵盐类杀菌剂均优于现场在用杀菌剂,当加注浓度为20 mg/L时,双季铵盐类杀菌剂可以将现场注水中的SRB,TGB及FB控制在油田标准以下,效果良好。更多还原

【Abstract】 Bactericides become more and more crucial in Bo Hai P oilfields due to the serious harms resulted from bacterium corrosion. Through adopting the dilution method,different bactericidal agents were tested. The results show that the dual quaternary ammonium salt and THPS are good bactericide for Bohai p oilfield. The SRB of injection water could be limited under25 个/m L,when the dual quaternary ammonium salt optimal concentration of was 20 mg·L-1.更多还原
