SRB是一种对油田十分有害的微生物 ,它能加快输油管道的腐蚀穿孔 ,而且使加工性能变坏。油田普遍采用投加杀菌剂法来抑制 SRB。甲硝唑对 SRB具有一定的杀菌能力 ,但由于其水溶性差而实际应用不广。实验将甲硝唑分别与氯苄、对长链烷基氯苄反应 ,形成含杂环的表面活性剂 、 ,并测试了 、 的红外光谱、物理特性及其对 SRB的杀菌效果。物质 、 具有很好的水溶性 ,并表现出较好的杀菌性能。 SRB is a very harmful microorganisms in the oil field, it can accelerate the corrosion of oil and gas pipeline perforation, but also to processability deterioration. Oilfield commonly used dosing bactericide to inhibit SRB. Metronidazole SRB has a certain bactericidal ability, but due to its poor water solubility and practical application is not wide. In the experiment, metronidazole was reacted with benzyl chloride respectively to react with long chain alkylbenzyl chloride to form a heterocyclic ring-containing surfactant. The infrared spectra, physical properties and bactericidal effect on SRB were also tested. Material, has a good water-soluble, and showed good bactericidal properties.
