Geochemical methods and examples for ascertaining corrosion fluid of palaeokarst oil-gas reservoir

摘要

With development of oil & gas exploration,the mechanism of palaeokarst forming have been attached importance to in the recent years.Macro and micro appraisal symbol of palaeokarst have been posed by technique of well drilling,logging,seismic and geological geomorphology.However,series research geochemical methods to identifying palaeokarst reservoir origin have not been established.
