Microbial prospecting of oil and gas (MPOG) is paid more a nd more attention by the whole exploration field, because of its many advantages such as direct display, effectiveness, economics and less multi-interpretation . With the new method of the microbial prospecting of natural gas, which is one of MPOG, applied to Manite depression of Erlian basin, the samples are collected and the methane oxidizing bacteria are cultivated, the following abnormal zones are classified. The two gas abnormal zones are north-western abnormal zone and middle-southern abnormal zone. Comparing the microbial results with the drille d wells in studied area, the accordance between them is satisfactory. Meanwhile, through the microbial prospecting of natural gas practices, the influence of th e soil surface and subsurface faults as well as the objectivity of the analytic results are concluded and discussed, which have much significance for Chinese co mplicated subsurface geo-structural natural fields to explore oil & gas. At las t, on the basis of the microbial results of gas indicator and combining with man y conditions such as traps and oil source, etc. The oil and gas potentiality is analyzed, and the optimal drilling site is also provided which are needed to be clarified in the future well drilling.
