| 中文摘要: |
| 储层宏观参数是储层微观参数的宏观体现。以孔隙度、绝对渗透率、相对渗透率等宏观参数作为约束条件,拟合生成网络模拟模型,在此基础上讨论了孔喉半径、喉道半径均质系数、孔喉比、孔喉润湿性、孔喉形状和配位数等微观参数的变化对孔隙度、绝对渗透率和相对渗透率等宏观参数的影响。在影响因素敏感性分析的基础上,确定了引起储层宏观参数变化的主要微观影响因素。 |
| 英文摘要: |
| In reservoir, the macro-parameters are the macro-reflection of micro-parameters. Network model is established according to the matching of micro-parameters including porosity, permeability and relative permeability. Based on network modeling, the influences of microscopic parameters such as pore-throat radius, homogeneity coefficient of throat radius, pore-throat radius aspect ratio, wettability, pore-throat shape and coordination number on macro-parameters such as porosity, absolute permeability and relative permeability are discussed. On the basis of the sensitivity analysis, the significant influential micro-parameters are determined. |
