本文从古生物特征、岩性特征及区域地层分布规律入手，对克参1井白垩系划分对比进行了详细探讨，并解释了白垩系厚度巨大及未钻遇侏罗系的原因。指出：井探2700～6150米地层归属白垩系，可划分为三个组，本井未钻遇侏罗系。
Based on palaeontological characteristics, lithological characteristics and distribution rules of regional stratigraphy, this paper discusses in detail the division of Cretaceous in Well Ketang 1 and explains the reasons why the Cretaceous is thick and has not encountered Jurassic. It is pointed out that the formations from 2700 to 6150 meters of well exploration belong to the Cretaceous and can be divided into three groups. The well did not encounter the Jurassic.
