Abstract: The organic macerals of low maturity source rocks of Es4 in Dongying Depression were classified andquantified by using microscope photometry,and the macerals were cassified into 6 groups as followsinerinite, vitrinite, exinite, sapropelinite, organozooclastinite and secondary group. thdr the property, composition and distribution in different depth and position of this depression. were also studied In ana-lyzing ,it showed that Palaeostomosystis minor is rich especially in some beds, with the common presenceof Botryococcus,Pediastrum sp andBohaidina sp. A direct proportionality exists between mineral itumi-nous groundmass and amorphous substance. In the low mature source rocks from the Domgying Depres-sion, amorphous substance was decomposed by low aquatic organisms and was further determined to beone of the major parent materials of oil and gas. Using the relationship between vitrinite reflectance and conversion efficiency of hydrocarbons and combining the thermal modelling the genesis hydrocarbon-generating and evolution patterns could be well understood from the viewpoint of organic petrology.
