    Abstract

    Results of the bazhenov formation rocks kerogen porosity study are provided in this work. System of pores is found in the kerogen of the rocks that are under catagenetic transformation corresponding to the end of the oil age. Pores were found both in kerogen of carbonate-siliceous and siliceous-radiolarian lithotype rocks and in clay-siliceous rocks of the "matrix". Using a high-resolution electron microscopy the structure of kerogen void space was studied. Pore size is up to 2 μm, pores are well connected with each other znd have a round, oval or teardrop shape. Void space in the kerogen is prone to pyritization, that negatively impact on the pore volume and their connection. Kerogen porosity depends on the catagenesis stage of rocks, and areas with high kerogen porosity consider to be collectors.
