摘　　要：综述中原油气区侏罗系地层古生物特征,提出该区存在下侏罗统—中侏罗统,未确证存在上侏罗统,过去所称上侏罗统—下白垩统归入下白垩统为宜。提出了区内北部临清坳陷的下侏罗统—中侏罗统地层可划分为中一下侏罗统的坊子组和中侏罗统的三台组、西南部济源凹陷下侏罗统的鞍腰组和中侏罗统马凹组、东南部黄口凹陷仅存在中侏罗统的三台组、南部中牟凹陷的侏罗纪地层与济源凹陷的相近,并提出了它们之间的对比意见。The present paper summarizes the stratigraphic and palaeontological features of the Jurassic System in the petroliferous region of the Zhongyuan Oilfield. We conclude that there are Lower-Middle Jurassic strata but probably no Upper Jurassic strata in this area. The previously recognized Upper Jurassic-Lower Cretaceous rocks are probably Lower Cretaceous. On this basis,we propose a Lower-Middle Jurassic stratigraphic classification and correlation scheme for this area.
