Quantitative characterization of microscopic pore heterogeneity in tight sandstones and its reservoir significance: A case study of the Shanxi Formation in X area, Ordos Basin

  • 摘要: 以鄂尔多斯盆地东部X地区山西组致密砂岩储层为例,采用Matlab编程,提出铸体薄片图像面孔率提取的新方法,基于面孔率提出非均质系数U定量表征微观孔隙非均质性,并讨论非均质系数U和储层物性关系及微观孔隙非均质性的储层意义。结果表明,X地区致密砂岩储层微观非均质性强烈,微观孔隙分布十分不均匀;非均质系数U与孔隙度和渗透率均为负相关关系,非均质系数U越大,储层非均质性越强,储层物性越差,反之储层物性越好;致密砂岩储层微观非均质性控制着孔隙(储集空间和渗流空间)的微观发育特征,致密砂岩储层非均质系数定量评价有利于指导后期开发、开采中优质层位的圈定。
