根据生物爆发等时性的原则,提出了柴达木盆地风西构造上油砂山组与下油砂山组对比的新界线,以这一原则对比到红沟子构造沟5井,提出了该井井深4000m上下的下干柴沟组油层应划为上干柴沟组油层。在岩屑录井微体化石地层对比中,提出了绘制正星介丰度曲线和通过识别正星介属出现的爆发点来对比地层的新方法。 Based on the isochronous principle of biological eruption, a new boundary line between the Upper Yingsashan Formation and the Lower Yanshan Formation of the Fengxi Formation in the Qaidam Basin was proposed. By contrast with this principle, 4000m up and down the Chaganchaogou Formation reservoir should be designated as Upper Ganchaigou Formation reservoir. In contrasting the microfacies fossil stratigraphy of debris logging, a new method of mapping positive exponential abundance curves and contrasting stratigraphy by identifying the eruption points of Zhengxing Mesh is proposed.
