| 摘 要： | 松辽盆地西缘土壤油气化探工作采用酸解烃法、紫外光谱法、荧光光谱法等分析测试方法，总结白城地区近地表甲烷、重烃、芳烃及其衍生物和蚀变碳酸盐的地球化学异常特征，圈定出七棵树Ⅰ级综合异常和前进马场Ⅲ级综合异常.七棵树Ⅰ级综合异常具有异常强度高、规模大的特征，异常区是白城地区最有利含油气远景区，且已有钻孔镇深1井取得较好的油气显示，是进一步勘探的主要方向.前进马场Ⅲ级综合异常规模小，指标组合简单，但强度较高，值得进一步关注.

| Abstract: | The analysis methods of acidolysis hydrocarbon, ultraviolet spectrometry and fluorescence spectrometry are used in soil geochemical exploration for oil-gas in the western margin of Songliao Basin to summarize the geochemical anomaly characteristics of methane, heavy hydrocarbon, aromatic hydrocarbon and its derivatives and altered carbonate, and delineate the Qikeshu grade-I composite anomaly and Qianjinmachang grade-III composite anomaly. The former is characterized by high anomaly intensity and large scale, with the most favorable oil-gas prospect of Baicheng area as the anomaly area and good oil-gas show in the borehole of ZS1 well, which is the main direction of further exploration, while the latter is in small scale with simple indicator combination but high anomaly intensity, worthy of further attention. |
