摘要
Calcareous nannofossils analysis has been carried out in 108 cuttings and 3 core samples from Well D in the JZ20-2 structure which is located in the Western Liaoning Lower Uplift in the Bohai Bay Basin.The paleontological assemblages in Well D have been established by integrating the calcareous nannofossils and other paleontological data.The stratigraphy in Well D can be subdivided into Jurassic,Shahejie Formation 2,Shahejie Formation 1,Dongying Formation,Guantao Formation and Minghuazhen Formation from the bottom up.The paper also discussed the source rock of the calcareous shale from the Upper Shahejie Formation.
