Objective:
Establishing a new method of microbial prospecting for oil and gas based on microbial community metabolic function.
Methods:
In this study, 45 shallow reservoir soil samples and 25 non-reservoir soil samples were collected. Carbon catabolic activity of the microbial community was measured by biolog microplate, and microbial anomaly of reservoir was judged by discriminant function.
Result:
We screened 10 typical carbon sources of 95 carbon sources which could reflect the differences of reservoir and non-reservoir soil microbial community structure and made the validation test set to experimental zone and controlled zone samples using the discriminant function. The discriminate rate of reservoir and non-reservoir were 97.8% and 100% respectively and the overall accuracy was 98.6%.
Conclusion:
Biolog technology provided a highly efficient and precise method for preliminarily predicting oil and gas reservoir.
