  • Well An'can-1 is the first stratigraphic well drilled in the Hefei Basin by Shengli Oilfield Co. Ltd. The depositional facies and reservoir characteristics of the Mesozoic were discussed based on the rock mineralogy and geophysical properties of the sequence. It showed a progradation for the Mesozoic sedimentation fron top to bottom with lake deposit in the Early Jurassic to ineterbedded lacustrine and fluvial deposit or fluvial deposit in the Middle and Late Jurassic to fluvial facies in the Early Cretaceous. The reservoirs in the Mesozoic sandstones were poor and were dominated by very low porosity and permeability. They may be effective reservoirs for gas accumulation.
