| 摘 要： | 通过水淹岩石岩电特性的实验研究发现,地层水矿化度的变化,对岩石电阻率幅值的影响较大,致使单一频率下的岩石复电阻率幅值和同相电阻率也会象常规电阻率一样,随着含水饱和度的变化,出现“U”形曲线,而相对而言,地层水矿化度对岩石频散特性的影响较小。因此基于岩石频散特性发展起来的复电阻率测井技术在识别油水层和水淹层测井评价上具有良好的应用前景。 |
| 关 键 词： | 复电阻率 水淹层 矿化度 "U"形曲线 多解性 |

| Abstract: | Based on experimental research on electrical property of waterflooded rock we have found that variation of salinity has much effect on rock resistivity,and it makes that relation curves of complex resistivity and in-phase resistivity of rock under single frequency with water saturation are characteristic of U-style curve,just like relation curves of waterflooded rock resisitivity with water saturation,but salinity variation has little effect on rock dispersion property.Therefore,there will be good prospect in determination of water bearing zone and oil bearing zone,and waterflooded zone with complex resistivity log developed with rock dispersion property. |
| Keywords: | complex resistivity water cut formation salinity U style curve multi-solution property |
