摘要对松辽盆地晚白垩世青山口组5口井岩心组成的复合地质剖面425个样品进行介形虫生物地层学研究。该组共建立了19个介形虫带，其中新建立3个，修订3个。详细描述了19个介形类带。该研究为松辽盆地青山口组与高台子油藏的详细地层划分和对比提供了依据。
Abstract: An ostracod biostratigraphic study was performed on 425 samples from the composite geological section constructed by using cores taken from five selected wells drilled in the Late Cretaceous Qingshankou Formation in the Songliao basin. A total of 19 ostracod zones are established in the formation, of which 3 are newly established and 3 are revised. The 19 ostracod zones are described in detail. This study provides a basis for the detailed stratigraphic division and correlation of the Qingshankou Formation and the Gaotaizi oil reservoir in the oilfield in the Songliao basin.
