| 摘 要： | 针对大庆油田高含水后期开发,油层内岩性、物性、含水性都已发生变化的特点,给测井资料确定水淹层饱和度参数带来很大困难,提出用岩电实验,进行地层岩电机理分析研究,确定不同注水矿化度下岩石电阻率变化以及Archie公式参数变化规律,从而提高解释精度.

| Abstract: | In view of high water cut stage of Daqing oil field,the lithology,physical,aquosity within oil layer had changed greatly which bring much difficulty in saturation determination of water-flooded zone by logging data.The paper provides a rock electric experiment so as to investigate rock electric mechanism and further determines rock resistivity variation of different waterflooding salinity and changing the regularity of Archie paramenter,thereby improves interpretation accuracy. |

| Keywords: | water-flooded zone rock electric experiment logging interpretation saturation index lithological factor |
