硫酸盐还原菌（SRB）是油田生产活动中一类重要的有害微生物，能在厌氧条件下以有机物为电子供体，将硫酸盐还原为硫化物，其引发的油田生产系统的腐蚀和污染比其他任何细菌都严重。用PCR-DGGE方法分析了陈2区块硫酸盐还原菌菌群的多样性，并鉴定了优势菌种，为SRB的针对性治理提供了可靠信息。研究表明，陈2区块优势菌主要为Desulfotomac-ulum、Archaeoglobus 和Desulfovibrio。

Sulfate-reducing bacteria (SRB)is an important class of harmful microorganisms in the oilfield production activiy.It can reduce sulfate to sulfide by using organic electron donor under anaerobic conditions.The corrosion and con-tamination caused by SRB are more serious than that of any other bacteria in the oilfield production system.By PCT-DGGE method,it is analyzed the diversity of SRB in block Chen2,and identified the predominant bacteria of sulfate-re-ducing bacteria.Research results showed that the dominant bacteria of the block are Desulfotomaculum,Archaeoglobus and Desulfovibrio.It provides reliable information for SRB targeted control.
