Petrophysical facies characteristics and classification evaluation of Dongying Formation of Nanpu No. 4 structure
Strong diagenesis and reservoir heterogeneity as well as complex pore structure in the late stage of No.4 structure in Nanpu sag make assessment of the petrophysical characteristics of its high-quality reservoir and evaluation of its effectiveness difficult.To address this, the sedimentary, diagenetic, Block of the Month Kits and pore structure cha
