摘要: 对松辽盆地新生界地质环境的研究表明,高的地温场、滞留区的缺氧还原环境、第四系和第三系大安组适合的水介质矿化度和pH值以及丰富的腐殖型有机质,有利于生物气的形成.河流、湖泊相沉积环境和良好的区域盖层及后期微弱的构造运动形成平缓的构造起伏有利于生物气聚集成藏.根据盖层、第四系和第三系大安组气源岩的分布特征,预测大庆长垣以西及南部大安、北部林甸一带是形成生物气藏的有利地区.

Abstract: The geologic environment in the Cenozoic of the Songliao Basin was analyzed.The conclusions show that high geothermal field, anoxic reduction environment in stagnant area,proper water medium mineralization and pH value in the Quaternary and Tertiary of Da'an Formation,as well as the rich humus organic materials are propitious to biogenic gas formation.The favorable fluvial and lake facies deposition environment,nice regional overlying rock,the structure relief resulted from upper weak tectonic movement are suitable for biogenic gas accumulation and reservoir.It is predicated that the areas in the western Changyuan in Daqing district and the southern Da'an and northern Lindian areas are favorable to generate biogenic gas reservoir,according to the properties of overlying rock and the distribution features of gas source rocks in the Quaternary and Tertiary of Da'an Formation.

Key words: Songliao Basin, Cenozoic, biogenic gas, reservoir condition, favorable areas, exploration potential
