摘　　要：孔店组为昌潍坳陷主要的烃源层 ,也是重要的储集层和盖层。由于钻穿孔店组的深井比较少 ,而且生物化石相对稀少 ,加之以前对岩心中的古生物分析不全面 ,因而制约了对研究区孔店组的认识。通过岩石、电性、生物、地震多方面对孔店组的系统研究 ,总结了孔店组的岩石、电性、古生物等方面的特征 ,进而确定孔店组内部界面 ,重新对孔店组进行分段 ,将孔店组的火山岩划归孔店组二段 ,划分出孔店组三段 ,为深层油气勘探提供准确的地层依据。鉴于孔店组划分的变化 ,结合地震剖面对孔店组的分布也做了相应的研究。A systematic stratigraphic study of the Paleogene Kongdian Formation in the Changwei Sag of Shandong is carried out by using lithologic, electric property, biologic, seismic, and other methods. The lithology, electric property and fossils are summarized, and thus the internal interfaces within the Kongdian Formation are determined. The division of the Kongdian Formation into members is made once again. The volcanic rocks of the Kongdian Formation are assigned to the No.2 Member of this formation and the No.3 Member is removed, providing the precise stratigraphic evidence for the deep exploration of oil and gas. In terms of the change in the division of the Kongdian Formation, the distribution of the Kongdian Formation is also studied with the combination of seismic data.
