| 摘 要： | 以分形理论为基础,结合压汞测试资料,计算了鄂尔多斯盆地东-韩地区延长组长2段储层孔隙结构的分形维数。结果表明,储层孔隙空间存在单一分形和多重分形的现象,中孔隙的分形维数大于小孔隙的分形维数,中孔隙的均匀程度差于小孔隙。分形维数与孔隙结构参数呈微弱的正相关性,分形维数越大,孔隙分布的非均质性越强。

| Abstract: | On the basis of fractal theory and mercury data, the fractal dimension of pore structure of Chang 2 division is calculated in Dong-Han area,Ordos Basin. The results show that pore structure has single fractal and multi-fractal features. Fractal dimensions of media pore are greater than them of micro-pore, which have better uniformity. There is a weak positive correlation between fractal dimension and pore structure parameters .The greater the fractal dimension is, the stronger the homogeneity of pore distribution is. |
