摘　　要：对萨北开发区高含水期砂岩油层的微观孔隙进行了研究,从岩芯切片入手,采用多向扫描、二维图像统计分析、随机模拟等多项技术,重建萨北开发区油层孔隙网络模型,再现油层微观几何特征,实现了定量计算储层岩石的宏观物性参数以及正确评价储层传导流体的能力,为开发区进一步挖潜(三次采油)提供了技术支持。Micro-pore structure of sandstone in high water content strata in Sabei Development Area was studied. On the basis of analysis of core slices by several technologies such as multi-directional scanning technique, statistical analysis of 2D-images and stochastic simulation, micro-pore network model of porous media in the studied area was rebuilt, and its microscopic geometrical feature reappeared. Based on the model the macroscopic parameters were gotten, and it can be used to evaluate seepage capability of oil reservoir. It supplies technical support to further exploitation of oil.
