再生型生物成因天然气是一种分布相当广泛的浅层天然气，它是浅层的油层、煤层在还原条件下受厌氧细菌（主要是产甲烷菌）降解作用新生成的一种再生能源。它突破了只能在热不成熟的地层中勘探生物天然气的束缚，将其勘探领域扩展到目前处于浅埋的热成熟含油含煤盆地以及某些含盐含碱盆地。它是我国今后浅层天然气勘探的重要领域，并可能成为代国生物气的主要资源类型。
Regenerative Biogenesis Natural gas is a fairly widespread shallow gas, a newly regenerated energy source produced by the degradation of anaerobic bacteria (mainly methanogens) under the reducing conditions in shallow oil beds. It breaks the shackles of exploring biogas only in thermally immature formations and extends its exploration to the shallow, hot, mature oil-bearing coal-bearing basins and some saline-alkali basins. It is an important field of shallow gas exploration in our country in the future and may become the main resource type of generation biogas.
