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。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.
