| 中文摘要: |
| 随着子洲-清涧地区上古生界碎屑岩气藏研究的深入，其物源问题引起了人们的关注。为查明物源问题，本文应用分形理论对山西组山23段的沉积物源进行了研究，系统的分析了铀、钍、钾测井曲线的分形特征、分形特征在沉积物源分析中的应用过程以及分形特征对沉积物源的响应机理。结果表明，铀、钍、钾测井曲线具有分形特征，其分形特征对沉积物源具有一定程度的响应，研究区内西北部物源控制区与东北部物源控制区具有不同的沉积物源分形响应特征，通过分形响应得到的沉积物源分析结果与已有的地质认识较为吻合。分形特征研究为沉积物源的分析提供了一种途径，具有一定的应用价值。 |
| 英文摘要: |
| With the furthering research of Paleozoic clastic gas reservoirs in the Zizhou-Qingjian area, provenance analysis has attracted much attention. In order to clarify this problem, fractal theory was used to study the provenance of the Shan23 formation in this area. Fractal characteristics of uranium, thorium, and potassium logging curves and their response mechanism were systemically analyzed. The results show that these curves have fractal characteristics, which are controlled by the same provenance in certain rules，and are different in northeast and northwest provenance areas. The provenance analysis results from the fractal response are consistent with the existing geological knowledge. Research of fractal characteristics provides a new approach to analyze sediment provenance, and has a certain application value. |
