Genesis and Implications of the Composition and Sedimentary Structure of Fine-Grained Carbonate Rocks in the Shulu Sag被引量：8
《Journal of Earth Science》2017年第6期1047-1063,共17页Xiangxin Kong Zaixing Jiang Chao Han Lijing Zheng Yiming Zhang Ruifeng Zhang Jianzhang Tian 
provided by the National Major Research Program for Science and Technology of China (No. 2017ZX05009-002);the National Natural Science Fund (No. 41772090)
Fine-grained carbonate rocks, which extensively occur in the Eocene strata in the Shulu sag, Bohai Bay Basin, North China, represent an unconventional, fine-grained carbonate reservoir. However, previous studies have ...
