摘要
以致密砂岩为代表的非常规油气储层孔隙空间复杂导致岩石物理实验测量周期长,成本高,难以定量研究微观参数对电阻率的影响,而以X射线CT扫描为基础发展起来的数字岩心岩石物理属性模拟技术则弥补了这种不足。系统总结了基于数字岩心电性数值模拟格子波尔兹曼方法、基尔霍夫电路节点法、随机游走法以及有限元法的优缺点,探讨了目前电性数值模拟研究存在的4个主要问题:1缺乏模拟更多微观因素的方法模型;2分辨率与储层非均质性之间的矛盾;3图像分割方法的局限性;4数字孔隙格架的多解性。指出了基于数字岩心电性模拟的4个发展方向:1精细三维孔隙网络模型的构建;2基于多阈值分割方法的图像处理;3电性模拟方法模型的优化;4基于数字岩心高性能并行计算技术。该研究有助于提高致密砂岩岩石电性数值模拟研究水平,为非常规储层勘探开发奠定坚实的基础。
