| 摘 要： | 依据常规岩电及核磁共振实验,分析了饱和度指数的影响因素,对其影响机理进行了定性研究,并根据分析结果建立饱和度模型,对实际井资料进行了处理。结果表明,储层岩石的孔隙结构是影响饱和度指数的最主要因素,而地层水矿化度对饱和度指数的影响较小。精确计算储层的饱和度指数,对储层流体定量评价具有重要意义。 |
| 关 键 词： | 饱和度指数 影响因素 低孔 低渗 岩电实验 核磁共振 定量评价 |

| Abstract: | On the basis of conventional experiments on petrophysical-electric property and nuclear magnetic resonance,this study analyzes the influence factors of saturation index,qualitatively studies the influence mechanism,builds up a saturation model,and processes actual well data.The results show that the pore structure of reservoir rock is the major influence factor of saturation index,and water salinity has little influence on saturation index.Accurate calculation of saturation index is of important significanc... |
