Zhu Huaiping, Li Wu, Wu Chuanzhi, et al. Roles of geochemical prospecting technique in exploration of subtle oil & gas reservoirs[J]. 2004, 25(3): 344-348.DOI: 10.11743/ogg20040321.
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.
