研究了江汉盆地潜江组一剖面样品的矿物学、岩石学、有机地球化学特征，结合这一盆地的其他研究资料，认为江汉盆地形成的未成熟油主要与碳酸沉积阶段形成的有机质有关，在未成熟油储量统计时，只有计算碳酸盐沉积阶段形成的沉积物才有意义．
Based on the mineralogical, petrological and organic geochemical characteristics of a section of the Qianjiang Formation in the Jianghan Basin, and combining with other research data in this basin, it is concluded that the immature oil formed in the Jianghan Basin is mainly related to the organic matter formed during the carbonate deposition. The statistics of immature oil reserves make sense only when calculating sediments formed during carbonate deposition.
