Title: Petroleum geological characteristics and exploration perspective in Nilga Basin, Mongolia
Abstract: 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.
