In this study,the use of amplified rDNA restriction fragment analysis (ARDRA) technology,through the establishment of 16s rDNA clone library of the Daqing oil field reservoir preliminary analysis of microbial communities.Amplified rDNA restriction fragment analysis (ARDRA) technique is based on the prokaryotic rDNA sequence of the conservative nature of the amplified rDNA fragments were digested by restriction mapping to analyze the diversity among bacteria.The results show that:Daqing oilfield microbial communities in two oil fields in order to Acinetobacter (Acinetobacter) as the main,there is a certain amount of Pseudomonas (Pseudomonas),Hyphomonas (raw silk Aeromonas spp),Oceanibaculum,Maricaulis is a bacteria.From the four time points analysis of bacterial DNA Database comparisons can be seen,with the incubation time of the extension and continuation of transit passage,Acinetobacter in the community to reduce the proportion of other species of bacteria gradually increased.
