长庆安塞油田注入水中硫酸盐还原菌、腐生菌会影响油田的正常生产,这二种细菌特性各异,相互之间还存在一定的联系。杀菌剂的选用应保证对长6层和长2层的这两种细菌有较好的杀灭作用,并辅以正确的投加方法和浓度方能保证油田正常生产。本文以长庆安塞油田长6和长2层采出水硫酸盐还原菌(SRB)和腐生菌(TGB)的杀菌处理为例,分别对AD52-168和QD-707两种型号杀菌剂的杀菌效果以探讨。
Changqing Ansai oilfield injection of sulfate-reducing bacteria in the water, saprophytic bacteria will affect the normal production of the oil, the two bacteria have different characteristics, there is still a certain relationship between each other. The selection of fungicides should ensure that the two bacteria of 6 layers long and 2 layers have good killing effect, and supplemented by the correct dosing method and concentration to ensure the normal production of oilfields. In this paper, the bactericidal treatment of sulfate-reducing bacteria (SRB) and saprophytic bacteria (TGB) in Chang 6 and Chang 2 layers of Changqing Ansai Oilfield was taken as an example. The sterilization of two types of bactericide, AD52-168 and QD-707, Effect to explore.
