摘要: 从地层温度、地层水含盐度、沉积速率、有机质丰度与类型、生物菌群、浅层的抑制作用等 6 个方面入手,详细分析了各因素对河套盆地新近纪—第四纪微生物活性、甲烷菌生长繁殖以及生物气形成的影响,发现河套盆地生物气源岩发育的有利层段位于第四系更新统中、上段。

Abstract: Starting with the six aspects such as formation temperature, formation water salinity, depositional rate, organic matter abundance and type, microbial population and shallow inhibition effect, this paper analyzes in detail each factor influencing the microbial activity, the growth and reproduction of methane bacteria and the generation of biogas of the Neogene-Quaternary in Hetao basin. It is revealed that the favorable layer of biogas source rock development lies to the upper and middle sections of the Pleistocene in Hetao basin.

Key words: Hetao basin, biogas, geochemistry, methane bacteria, genesis, origin
