【摘要】 论述了细菌成因气、热成因气、深层气和非生物成因气的物质来源和成气机制,指出,不同物质来源、不同成气机制和成气环境,构成了天然气的多种成因类型和不连续成气特征。评述了深层气、非生物成因气研究进展和它们的资源前景。讨论了形成非生物成因气的聚合反应和同位素动力学分馏效应以及鉴别非生物成因气的地球化学指标的有效性。认为松辽盆地诸多气井天然气的非生物成因特征,为研究和寻找非生物成因天然气资源提供了一个典型实例;松辽盆地昌德-肇州西和徐家围子深层气勘探的重大突破,使该盆地非生物成因气的储量超过500×108m3,展现了松辽盆地非生物成因气的良好资源前景。更多还原

【Abstract】 The paper discusses sources and formation mechanism of microbial gas,thermogenic gas,deep gas and abiogenic gas.Pointing out deferent source,deferent formation mechanism and gas formation environment make various origin types and a non-continue characteristics,support to a broad prospect for investigating and seeking natural gas resources.Reviewing advances in abiogenic natural gas studies and a prospect for abiogenic gas resource.Discussing the mechanism an abiogenic origin via polymerization and kinetic fractionation effects of carbon and hydrogen isotopes.更多还原
