通过对南堡2号构造岩芯的分析化验、单井测井解释等资料的分析,结合沉积微相,对南堡2号构造东一段储层的岩石学特征、物性及非均质性进行深入研究。研究表明,该区块东一段储层主要岩石类型为细砂岩;储层物性条件好,为中孔、中渗型,储层非均质性强。通过对该块储层和隔间层特征的研究,确立剩余油的分布规律具有重要意义。 Based on the analysis of Nanpu No.2 structural core, single well log interpretation and other sedimentary microfacies, the petrological characteristics, physical properties and heterogeneity of the Dongba Member of the Nanpu No.2 structure are studied In-depth study. The study shows that the main rock type in the first member of the block is fine sandstone. The reservoir has good physical properties and is medium-mesoporous and medium-permeability with strong reservoir heterogeneity. It is of great importance to establish the distribution rule of remaining oil by studying the characteristics of the reservoir and the compartment.
