该文介绍了新疆石油管理局克拉玛依石化厂炼油化工研究院自行研制、开发的ＫＢＳ系列微生物菌种筛选过程及使用性能，并对ＫＢＳ菌液现场施工效果及其适用条件进行了研究。１９９６ 年至１９９８ 年，新疆油田用ＫＢＳ系列微生物共施工８６ 口井、２３３ 井次，增产原油１４３５８．３ｔ，投入产出比达到１∶５ 以上。通过三年的现场应用表明，该系列微生物在新疆油田增产效果明显，具有施工简单、投资少、见效快等特点。
This article introduces the KBS series of microbial strain screening process and performance, which is developed and developed by Petrochemical Research Institute of Karamay Petrochemical Plant of Xinjiang Petroleum Administration. The construction effect of KBS strain and its application conditions are also studied. From 1996 to 1998, a total of 86 wells were drilled in KBS series of micro-organisms in Xinjiang Oilfield. 233 wells were drilled, yielding 14,358.3t of crude oil and the input-output ratio reached more than 1: 5. Through three years of on-site application shows that the series of microorganisms in Xinjiang oilfield yield significantly, with simple construction, less investment, quick and so on.
