油田生产中的细菌危害与杀菌技术

Bacterial Harm and Bactericidal Technology in Production of Crude Oil

在油田生产过程中，常常要使用多种有机化学药剂，加上其他环境条件（如温度、pH值、无机盐、溶解氧等）的适宜，往往会造成钻井液、完井液、压裂液、污水、注水的细菌污染，为了保证油田生产的正常进行，必须采取有效的措施控制细菌的危害。本文介绍和讨论了油田生产中的细菌危害及其杀菌技术，指出新型杀菌剂应向一剂多效方向发展。

Abstract : Many organic chemicals are often used in oil field production , together with suitable enviromental conditions(such as temperature, pH value , inorganic salts and dissolved oxygen etc.) , bacteria pollution of the drilling fluid , completion fluid, fracture fluid, waste water and injection water may be occured. In order to assure normal operation of oil field , effective measures of control of bacteria harm must be taken . In this paper , the bacterial harm and bactericidal technology are introduced and discussed and new bactericide with mutiple effect is pointed out as future direction of development.
