摘　　要：以岩性组合及牙形石化石资料为基础,同时以油气勘探所倚重的测井曲线为主要参考,对冀中油气区众多钻井所揭示的奥陶系进行了系统研究,统一了油气区内部地层划分标准,理清了横向对比关系;以岩性组合及牙形石化石群特征为主要依据,同时借助于海平面变化这一线索,讨论了冀中油气区奥陶系与鄂尔多斯盆地钻井剖面、河北唐山、邯郸、山东淄博,以及河南北部露头剖面奥陶系的对比关系;进而对冀中油气区奥陶纪岩石地层序列进行了修订,使之可以在华北地区推广应用。Based on lithostratigraphic and conodont biostratigraphie data from drill cores and reference out- crops in the Central Hebei Oil Area, a systematic research on Ordovician stratigraphy was carried out in order to establish stratigraphic subdivision and improve stratigraphic correlation in the study area. Based mainly on lithostratigraphic and conodont biostratigraphic data, stratigraphic correlation was proposed for Ordovician strata in Tangshan and Handan in Hebei Province, Zhibo in Shandong Province, and northern Henan Province. Stratigraphic revisions were proposed for Ordovician successions in the Central Hebei Oil Area.
