The research indicated a distinct anomalous high porosity zone of Ess4 in 3 000-4 000m depth range in Bonan Sag. Combined with core physical property data,the paper identified normal and abnormal porosity distribution,utilizing the distribution of reservoir porosity in continuous interval depth and curves of porosity changing with depth. Integrated with thin section data,scanning electron microscopy analysis and formation pressure data,the paper explained reasons for high porosity and permeability zone by aspects of diagenetic erosion,abnormal high pressure and hydrocarbon charging at early stage. Combined with microfacies,lithofacies,development fracture,the paper discussed the genetic mechanism of high quality reservoir. The result suggests that anomalous high porosity zone in reservoir was benefited by protection of overpressure,organic acid dissolution and hydrocarbon emplacement at early stage. The main conditions of high quality reservoir were as followings:development of anomalous high porosity zone|original deposition factors such as advantage facies(underwater distribution channel and mouth bar in fan delta front),relatively high proportion of mid-coarse rigid particles(quartz,feldspar and metamorphic fragments) and fracture development.
