摘要
前人将巴参１井井深１８８２～１９７７ｍ划归下二叠统南闸组，将井深１９７７～２０９４．５ｍ划归上石炭统小海子组，经“七五”、“八五”科技攻关研究，从 化石资料，巴参１井井深１９１０～２０７５ｍ，自上而下含有Ｐｓｅｕｄｏｓｃｈｗａｇｅｒｉｎａ，Ｔｒｉｔｉｃｉｔｅｓ带，但与之相当的巴探２井地层包括Ｔｒｉｔｉｃｉｔｅｓ，Ｆｕｓｕｌｉｎｅｌｌａ带，结合岩石地层、测井地层、地震地层、接触关系及与邻区对比，综合分析认为，巴参１井井深１８８２～２０９４．５ｍ地层归属上石炭统比较合适，并且暂时以“小海子组”作为地层单位使用。
The intervals from 1822m To 1977m and 1977 m to 2094.5 m have been divided into Nanzha Group of the Early Permian(P1n) and Xiaohaizi Group of the Late Carboniferous(C2x) in well BC1.As the 7th and 8th national '5-year' projects invoicing exploration,by fossil datas we know that it contains Pseudoschwagerina, triticites from 1910m to 2075m in well BC1, but it contains triticites, Fusulinella in the same interval in well BC1. According to rock, logging, seismic stratigraphy and contact relation,and based on comprehensive analysis, we consider that the interval from 1882m to 2094.5 m should be regarded as the lute Carboniferous, it is named: 'Xiaohaizi group' as the statigraphic unit temporarily.
