| 摘 要： | 在研究松辽盆地（松嫩平原南部）土壤样品中与油气化探相关的I、S、Cl、Sr四种微量元素地球化学场数据特征的基础上，应用传统方法和分形方法分别确定其地球化学异常下限，并对研究区土壤元素地球化学异常区域进行了固定。通过对比，发现分形方法圈定的异常区域与已知油气区吻合更好，该方法既避免了遗漏有用的油气信息，同时也剔除了部分干扰因素。

| Abstract: | This paper analyses feature of I, S, CI, Sr geochemical field data which correlated oil and gas geochemical ex- ploration in soil samples of Songliao basin, and operated in traditional method and fractal method to determine other anomaly lower threshold, then delineated geochemical anomalies regioru Through comparing, it is found that the results using fractal method are better, which avoid to omission oil and gas information, and reject some interference factors. |
