摘　　要：为了在油气田开采中准确地判别油气层，根据阿尔奇公式的基本原理，探讨了用真电阻率与侵入带电阻率交会图判别油气层的方法。用此法可判别出低电阻油层、气层、高气油比层和油层，具有较强的实用性。According to the principle of Archie equation, this paper puts forword the method using Rt-Ri crossing plot to discriminate oil and gas reservoir. This method can discriminate low-resistivity oil reservoir,gas reservoir, high gas-oil ratio reservoir and oil reservoir, therefore, it is more practical and adaptable.
