| 摘 要： | 对近 40 0块油田泥质砂岩样品测量结果进行了分析 ,给出了干岩样和含水岩样的介电频散曲线。由频散曲线看出 ,射频段 (2 0～ 2 70MHz)岩石介电常数随频率的变化服从幂函数规律 ,在此射频段中 ,可以实现频率的归一化 ,消除在不同频率下对同一地层测量结果的差异。同时 ,岩石介电频散程度受到含水饱和度、水矿化度、泥质含量等因素的影响

| Abstract: | The dielectric dispersion curves of the dry and water saturated rock samples are given based on the experimental results of 400 rock samples. The power law for frequency-dependent dispersion of the dielectric constant in the range of 20～270MHz is found. The degree of of dielectric dispersion is affected by water saturation salinity of water and clay quantity. |

| Keywords: | radio frequency rock dielectric constant dispersion saturation salinity clay quantity |
