储层条件下岩石样品电性参数测定及规律

DETERMINE AND REGULARRITY OF RESERVOIR ROCK SAMPLE ELECTRICITY PARAMETER

从理论上探讨了岩矿石的导电机制及岩矿石导电的影响因素．在此基础上，重点介绍了在高温高压条件下，对不同岩性、不同饱和度及不同油水比情况下岩石样品的测量装置与测量技术，并给出电阻率、极化率测量结果．最后，对测试的结果进行了分析，得出了某些规律性认识．

In this paper, conduction mechanism and conduction effect element of rock and ore are investigated. On this basic, the test array and test technic are narrated, test result for resistivity and chargeability are gived too under condition of high temperature, high pressure for different rock, different saturability, different ration of oil to water. Last, through to analyse thes resules of test, some regular cognition are got.
