Based on analyzing the combination of geochemical indicators, the affecting degree of factors, the regional geochemical change, and the relationship between oil and gas, the authors establish the methods and effective combination of indicator series to search on natural gas exploration in Hangjinqi area of Ordos Basin so as to analyze the region background and the preference of anomalies. The analysis of regional geochemical background, geochemical indicators highlighted in the law of space distribution reveals the abnormal and the intrinsic link between oil and gas, pointing out that the geochemical indicators of oil and gas abundance and low variability of the background belongs to the scope of non-uniform field.
