| 摘 要： | 初步总结了油气化探中存在的4方面干扰因素:①地表特殊景观的干扰;②土壤性质引起的干扰,包括土壤粘土矿物、化学成分、土壤酸碱度;③地下非油气矿源的干扰,如断层、高碳质及煤层、岩体和地层等的干扰;④其它,如污染河流的影响。并指出形成干扰异常特征和消除方法。

| Abstract: | It is of great importance to study and identify geochemical anomalies caused by some interfering factors and find out the eliminating methods in developing and applying comprehensive oil and gas geochemical exploration techniques so as to recognize the real anomaly information associated with oil and gas activities. Four interfering factors have been preliminarily summarized as follows: ①interference of surface special landscape; ②interference caused by soil characteristics such as clay minerals in soil, chemical compositions and soil acidity; ③underground non-oil and gas sources like faults, high carbon matter or coal layer and rocks; ④other factors, such as pollution, river flow or atmospheric influence. Characteristics of interfering anomalies and their eliminating method are also discussed. |
