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 the lithologic data and the data of conodont fossils, taking the well logging curves relied on by oil and gas exploration as the main reference, the Ordovician revealed by many drilling wells in the Jizhong oil and gas region was studied systematically, Stratigraphic criteria were used to clarify the horizontal contrast. Based on the features of lithologic assemblages and conodont fossils, the drilling profiles of the Ordovician and Ordos basins in the Jizhong oil and gas region were discussed with the help of clues of sea level changes. Hebei, Tangshan, Handan, Zibo, Shandong, and the outcrop of Ordos Basin in northern Henan Province. The sequences of the Ordovician lithostratigraphic sequences in the Jizhong oil and gas region have been revised so that they can be popularized and applied in North China.
