The principle and characteristics of Supercritical fluid extraction (SFE) were summarized in this paper. The supercritical fluid extraction experiments were carried out on the source rocks of Jiyang depression, using carbon dioxide as fluid. Three main factors of pressure, temperature and time that influence the extraction efficiency of SFE were chosen for the conditional experiments. Furthermore, the effects of variation of the three factors on the extraction efficiency were investigated, and the optimum condition was suggested to the pressure of 24 MPa, the temperature of 50℃ and the time of 30 mins. The method of SFE for soluble organic matters in source rocks was established. Using GC and GC\|MS, the biomarker parameters of the extracts by SFE were compared with that of by SE. The results showed that the SFE can substitute for SE. Furthermore, the SFE reserved more low carbon number hydrocarbons and was an available approach. The yield of hydrocarbons from the upper section of 4th member of Shahejie Formation in the south slope of Dongying depression was studied by SFE and it was found that SFE has superiority in the calculation of yield of hydrocarbon.
