摘要(Abstract)：

位于蒙古国中部的尼尔金盆地是一个中生代裂谷盆地,目前仍处于勘探早期。盆地内下白垩统湖相泥岩和纸状页岩具有很强的生油能力,下白垩统的煤系地层及上二叠统一下侏罗统中富含有机质的泥岩和煤层是可能的气源岩;盆地内广泛分布着3套储集层;上侏罗统、下白垩统、上白垩统的泥岩是潜在的盖层;存在多种生储盖组合及远景圈闭类型。通过对石油地质条件的分析,认为尼尔金盆地很可能形成多套含油气层系和多种油气藏类型,推测在盆地中部和南部会有大的油气藏存在。
Located in the middle Mongolia, Nilga Bbasin is a Meso-zoic rift basin and is in the early exploration stage at present. In the light of systemic analysis of petroleum geology in the Basin, it is considered that mudstone and coal layers in the Lower Cretaceous lacustrine facies have strong capacity to generate oil and organic-rich mudstone and coal layers in the Upper Permian to Lower Jurassic are also possible source rock to generate gas. There are three reservoirs broadly distributed in Nilga Basin and mudstones in the Upper Jurassic, Lower Cretaceous and Middle Cretaceous are potential seal beds. There are many kinds of combinations of source rock, reservoir and seal bed and perspective trap types in the Basin. According to analogy of petroleum geology conditions, it is considered that Nilga Basin might form a lot of hydrocarbon-bearing formations and many kinds of reservoir types and has a good exploration potential. It is speculated that there are large hydrocarbon reservoirs in the middle and south part of the Basin.
