摘要：Deep-burial sandstone reservoirs host significant hydrocarbon reserves and are the potential area for petroleum exploration. The deeply buried (＞4000–4500?m) Paleozoic reservoirs in Western Desert, Egypt are recently characterized by giant oil and gas discoveries. However, the debates about their sediment sources and formation mechanisms hamper further hydrocarbon exploration and development. Detailed core observations, geochemical and porosity-permeability analyses are performed to fill above gaps. The Paleozoic sandstone reservoirs are well-developed, including the Cambrian–Ordovician Shiffah Formation (av. porosity of 6.6% and permeability of 6.01?mD), Silurian Basur Formation (7.4% and 44.64?mD), and Carboniferous Desouqy Formation (8.7% and 76.44?mD). Their sedimentary facies is predominantly composed of fluvial and coastal facies. The predominant sediment sources for the Paleozoic clastic rocks are the Precambrian medium-acidic felsic basement, while the Precambrian sedimentary rocks provide certain sediment sources based on geochemical data. The development of Paleozoic reservoirs in the Western Desert is the integrated result of a
