The Mesozoic source rocks haven't been systematically studied in the west Linqing Depression,which restricted the exploration of Mesozoic in this area.Source rocks were analyzed by drilling and seismic data combined with geochemical data,the study shows that Mesozoic source rocks mainly distribute in Qiuxian Sag and Nangong Sag.They include two types,one is coal seam of Fangzi Formation in Lower-Middle Jurassic,the other is dark mudstone and oil shale formed in semi-deep to deep lake of Qiucheng Formation in Lower Cretaceous.Coal seams of the Fangzi Formation are moderate-to-fair source rocks,dark mudstone and oil shale of the Qiucheng Formation are moderate-to-good oil prone source rocks.Mesozoic source rocks of Qiuxian Sag have experienced two thermal evolution stages,i.e.,the first hydrocarbon generation occurred in the Late Cretaceous,generated coalbed gas and a small amount of low-mature oil;the second oc[JP2]curred in the Paleogene,mainly generated pyrolytic gas.The source rocks of Nangong Sag in Paleogene,mainly generated mature oil.Lower Cretaceous has supper-thick dark mudstone with better organic matter,forming source-reservoir-cap assemblage of self-generation and self-accumulation,which is highly prospective resource.
