摘　　要：哈萨克斯坦滨里海盆地北部是一个富油气区,已发现39个油气田,下二叠统和下石炭统是其中的重要产层,近几年的勘探表明,中石炭统的巴什基尔阶发育鲕粒滩及生物滩相灰岩,这些滩相灰岩的发现有可能使中石炭统成为一个新的勘探目的层系。立足勘探资料,对巴什基尔阶滩相灰岩的宏观和微观特征予以系统描述,将为今后的油气勘探提供一个重要线索。The northern part of the Pre-Caspian Basin of Kazakhstan is rich in oil and gas, in which 39 oil andgas fields have been found. Lower Carboniferous and lower Permian strata constitute important oil and gasproducing horizons. Recent exploration indicates that there exist lots of beach facies limestones of MiddleCarboniferous Bashkirian stage, suggesting that the Middle Carboniferous strata may become a new explorationtarget. Based on the exploration data, this paper has made a detailed description of macroscopic and microscopicfeatures of Bashkirian beach facies limestones, which will provide an important clue to future oil and gasexploration.
