摘要: 利用岩芯扫描仪对ZK6岩芯元素和磁化率进行快速扫描, 选取了K、Rb、Ba、Ti等元素以及磁化率特征曲线作为指标。通过扫描结果与样品所代表的地层进行对比分析, 探讨了运用岩芯扫描仪进行快速沉积相划分的可行性。分析认为岩芯扫描仪的输出结果中, K、Rb、Ba、Ti、Cr、Co、V元素相对含量以及磁化率特征曲线与样品地层的3个沉积旋回有很好的相符性。

Abstract: The drill core ZK6 was scanned by a core scanner to obtain relative amounts of objective elements and magnetic susceptibility of sediment. Choose elements (involving K, Rb, Ba, Ti, and the like) and the characteristic curve of magnetic susceptibility as indexes, the feasibility of sedimentary facies discrimination was assessed based on the employment of a core scanner, which was achieved by comparing the scanning results with the layers where the samples were taken. The results suggest that both relative amounts of elements, such as K, Rb, Ba, Ti, Cr, Co, and V, and the characteristic curve of magnetic susceptibility are well in accordance with the three sedimentary cycles with respect to the layers.

Key words: core scanner, characteristic curve, sedimentary facies
