油气的运移聚集和微渗漏作用都会引起地球化学环境的变化，导致油气田上方土壤中与有机质结合紧密的微量元素发生贫富变化。海量的多目标区域地球化学调查资料可以提供油气勘查的区域地球化学信息。利用松嫩平原南部多目标区域地球化学调查数据，结合松辽盆地已知油气田上方微量元素反映油气异常的效果，认为 Cl、S、I、Sr、CaO、TC、Br 等微量元素指标与油气田区存在着响应关系，为该区预测油气的有效指标。

Migration, accumulation and micro?leakage effects of oil and gas will lead to changes of the geochemical environment and the concentration of trace elements which are closely related to organic matter in the top of soil. Data of multi?objective regional geochemical survey will provide the regional geochemical information. Based on using multi?target regional geochemical data obtained from southern Songnen Plain, in combination with the abnormal results of the trace elements which are related to known oil and gas fields, the authors have detected that there exists response relationship between such indicators of trace elements as Cl, S, I, Sr, CaO, TC and Br and oil and gas fields, and hence these indicators are effective indexes in oil and gas prognosis.
