The contribution of hydrocarbon conversion to reservoir space of the shale in the lower E_s³ and the upper E_s⁴ in the Dongying Sag of the Bohai Bay Basin is discussed according to the volume change of kerogen in the process of hydrocarbon generation. The results show that the porosities within organic matter are very limited for the shale with low abundance of organic matter （TOC content ＜2% ）; however, for the shale with higher abundance of organic matter （TOC content ＞4% ）, the porosities formed during hydrocarbon generation process can reach 4% in the higher mature stage. In the Dongying Sag, the upper E_s⁴ section has a higher maturity, and the porosities within organic matter are widely developed during hydrocarbon generation in the deep depression. For comparison, it has a much lower organic maturity and porosity, and only locally developed in the lower E_s³.
