Geologic and Geochemical Conditions of Shale Oil of Paleogene in NanPu Sag of Bohai Bay Basin

Abstract:

The exploration practice in NanPu Sag suggests that shale oil&gas as an unconventional natural gas resource,is a kind of current alternative energy resource. According to measured data of geochemistry,mineral,logging and drilling on the Palaeogene strata in NanPu Sag,the shale in palaeogene characterised by large thickness,high abundance of organic matter, favorable types and wide range of thermal maturity, shows that it has the material basis for the formation of shale oil. In addition,the shale of palaeogene in NanPu Sag generally developed fractures,which has fine reservoir property. The shale in this area has high content of brittle minerals which are useful to later fracturing reformation. It is thought after comprehensive analysis that shale oil&gas of paleogene in NanPu Sag has a bright prospect in exploration and development.
