| 摘 要： | 地层水电阻率是测井解释中一个极其重要的参数,以纯地层条件推导的用于确定地层水电阻率的自然电位理论模型不适合泥质砂岩地层。针对含油气泥质砂岩储层,提供了改进的自然电位模型,它考虑到阳离子交换容量、含油气饱和度的影响,提供改进的自然电位模型可以有效地用于确定泥质砂岩地层的地层水电阻率。

| Abstract: | Formation water resisitivity is one of the key parameters in log interpretation.But the clean sand model through which we can calculate for- mation water resisitivity is unsuitable for argillaceous sandstone.This paper introduces a new model in which the effects of cation exchange capacity and hydrocarbon saturation are taken into consideration.It can provide perfect formation water resisitivity in argillaceous sand- stone by using SP(spontaneous potential)data. |

| Keywords: | formation water resisitivity SP(spontaneous potential) argillaceous sandstone reservoir |
