| 摘 要： | 求解目的层含水饱和度时应首先求出该层的Rw，再代入阿尔奇公式，水层Rw与油层Rwi常常不同，利用水层的Rw求目的层的电阻增大率I，有时出现I＜2，此时将油层定义为“低电阻率油层”是不准确的，陆相储层测井解释方法应不同于海相储层测井解释方法。

| Abstract: | Formation water resistivity ( R w) of intervals of interest shonld be first determined while gaining water saturation of the intervals, than put it into Archie equation. R w is often different from oilbed bound water resistivity ( R wi ). I <2 often appears when I of the intervals is obtained from R w ,in this way,it is wrong to define oilbed as low resistivity pay zone. Log interpretation of terrestrial reservoir is not the same as that of marine reservoir. |

| Keywords: | low resistivity pay zone interval of interest resistivity continental deposit marine deposit log interpretation correction |
