滨南油田沙二段薄层砂岩储层特征研究

采用微孔渗仪、扫描电镜、能谱分析、图象分析等储层实验室测定技术，对滨南油田沙二段储层进行岩性特征、物性特征、孔隙类型及结构特征、储层潜在敏感性特征、储层非均质性的研究，从而得出：三角洲前缘亚相分布的河口砂坝、远砂坝和席状砂体，因其砂质纯净，分选好，具良好的储油物性，且与有利于生油的前三角洲亚相紧密相邻，为有利含油相带。

Study on the Properties of Thin Sand Reservoir in the Second Member of Shahejie Formation in Binnan Oilfield

Adopting the testing techniques of microvoid percolation apparatus, scanning electron microscope, energy spectrum analysis and image analysis, a study is made on the lithologic features, physical character, type and structure of pore, latent sensitivity and heterogeneity of reservoir of the 2nd Member of Shahejie Formation in Binnan oilfield, It is concluded that the debouch bars, distal bars and sublacustrine distributary channel in the delta front part are good facies zone for gas and oil.
