三嗪类脱硫剂对某油田硫酸盐还原菌的影响研究

The influence of the triazine H_2S scavenger for SRB in the oilfield

针对渤海某油田脱硫剂换型后产液中硫酸盐还原菌(SRB)大量滋生的问题进行了原因分析,得出了SRB大量滋生是由于脱硫剂换型引起的结论。通过对三嗪类脱硫剂作用机理进行分析及相关实验,得出了甲醛与THPS复配后杀菌效果增强的结论并通过实验优化了杀菌剂的配方。

After analyzing the SRB increasing problem of the Bohai oilfield reaching a conclusion that the SRB increasing problem is because of the switch of the different kinds of H2S scavenger.After analyzing the mechanism of the triazine H2S scavenger and through some experiments reaching a conclusion that the THPS and formaldehyde use together can get a better effect of sterilization for the SRB and get a new kind of the biocide of SRB through the match of THPS and formaldehyde.
