济源盆地下第三系济源群划分对比新认识

New knowledges about division and correlation of Lower Paleogene Jiyuan Group in Jiyuan Basin

以地震资料为主要依据进行了综合研究，完善了下第三系济源群的地层层序，将它重新划分为韩庄组、聂庄组、泽峪组、丁庄组和冢头组；纠正了以往钻井地层的错误对比，将济２井的济源群叠置于济３井的济源群之上；证实下第三系济源群的厚度不止３０００ｍ，最大厚度可能达８５００ｍ。

This paper is mainly based on the seimological data. Synthetical study of the stratigraphic sequence of the Lower Paleogene Jiyuan Group is carred out in this paper,which are redivided into the Hanzhuang, Niezhuang,Zeyu, Dingzhuang and Zhongtou Formations. The mistakes in the stratigraphic correlation of drilling strata before are corrected in this paper. J2 well of the Jiyuan Group is superposited on the J3 well. The thickness of lower paleogene Jiyuan Group is proved to be over 3000m, probably reaching 8500m.
