This paper was conducted on the shale reservoir in the Dongying depression in the Shahejie Formation of Paleogene. Based on detailed core description, rock thin sections, argon ion polishing, scanning electron microscopy (SEM) analysis, CT scanning and carbon-oxygen isotopic test, the formation mechanism of the inter-laminar fractures (or seams) and their development conditions were discussed by comprehensive...
A fluid inclusion fluorescence and microthermometric study was performed on sandstones from the deep Es4 reservoir rocks of the Minfeng (民丰) sag, north of Dongying (东营) depression.
