Abstract:

Geochemical prospecting techniques, with the advantages of high reliability,adaptability,flexibility,economy and continuity,can play an important auxiliary role in exploration of subtle oil/gas reservoirs.Examples,such as Shuanghe,Renqiu and Ansai oilfields,show that near-surface geochemical responses are strong in subtle oil and gas reservoirs and have explicit geological significances.Geochemical prospecting techniques can be used to discover subtle oil/gas reservoirs,guide seismic prospecting, delineate limits of oil/gas reservoirs,evaluate oil/gas shows in the trap and discriminate fluid attributes.

Key words: geochemical prospecting technique, survey, subtle oil/gas reservoir, role
