| 1. | Three kinds of microbe , i . e . methane - oxidizing bacteria , anaerobic cellulose - decomposing bacteria and sulfate - reducing bacteria , were selected for experimental study , so the disturbance of surface biochemical effect was effectively inhibited , thus causing the microbiological anomaly to be able to reflect objectively the deep - seated hydrocarbon micro - leakage , it is pointed out that the result of predicting subsurface hydrocarbon distribution by use of the microbiological anomalies is obvious
选择三种微生物指标：甲烷氧化菌、厌氧纤维素分解菌和硫酸盐还原菌进行试验研究，有效地抑制了地表生物化学作用的干扰，使微生物异常能够较客观反映地下深部油气微渗漏情况，微生物异常预测地下油气的分布，效果显著。 |
