Abstract: It has been performed that investigating the mixed oil in reservoirs from Niuzhuang to Bamianhe oilfield with organically geochemical method. Using mature oil in Niuzhuang oilfield from Es3 source rocks and lowmature oil in Bamianhe oilfield from Es4 source rocks as two end members, to make cross plots of gammacerane/C30hopanoid ratio and hopanoid/sterane ratio, rearranged monoaryl sterane/C27βS monoaryl sterane ratio and the content of aromatic sterene, then calculated the oil mixed rate based on the cross plots. The result indicated that the mixing ratio of oil from Es4 source rocks step up from Niuzhuang subdepression to Bamianhe oilfield, and got similar data from two cross plots. Mature oil form Es3 source rocks dominated in the centre of Niuzhuang subdepression, low mature oil from Es4 source rocks dominated in Bamianhe oilfield, and two type oil mixed in Wangjiagang oilfield.
