The results of Rock-Eval, microscope observation, organic elements and vitrinite ref1ectance analysis of 45 source rock samples from Yanchang Formation, Xifeng Oilfield, Ordos Basin, used for researching the geochemical characteristics and assessing the hydrocarbon potential,suggest that the source rocks in Member 7 and 8 of the Yanchang Formation are relatively rich in organic matter and the medium and good ones account for 94% and 77%, respectively; most of the organic matter in the two members was humic-sapropel; and the source rock thermal evolution developed at a mature stage with favorable conditions for oil generating.
