摘要
生物成因气在全世界范围内具有广阔的勘探前景。国外生物成因气研究经历了摸索阶段、探讨阶段和理论形成阶段,形成一套较为可靠的识别方法,并在一些盆地勘探开发中获得了成功。中国具有大面积分布的非常规油气资源,其中煤层气和页岩气已得到了很好的研究,但对生物成因气还未开展实质性工作,其评价基础还略显薄弱。通过分析国外生物气研究方法,认为中国应尽快开展生物成因天然气的基础理论工作,特别是浅层源岩中生物气的成因、聚集、保存及成藏等方面的研究,以完善中国非常规油气资源评价。
Microbial methane is of a broad exploration prospect worldwide.Overseas studies on microbial methane have experienced a series of exploration,research and theory-formation processes,thus forming credible methods for gas identification and having success with microbial methane exploration and development in some basins.There are large quantities of unconventional hydrocarbon resources in China,Like coal-bed methane（CBM） and shale gas which have been well investigated,but for microbial methane which has less been studied and weakly assessed.Through reference of foreign research on microbial methane,the paper proposed that it is of great significance and urgency to carry out theoretical studies on microbial methane in China,especially studies on the origin,accumulation,preservation and occurrence of microbial methane from shallow source rocks,so as to complete resource assessment of unconventional hydrocarbons in China.
