摘　　要：长期以来,低电阻率油气层的识别问题一直是测井解释的一项难题,正常的油气层电阻率曲线的数值高于水层,但有些油层的电阻率低于水层,甚至出现了比泥岩还低的现象,近年来通过引进核磁共振和阵列感应等新技术测井方法已经解决了部分难题,但在未进行新技术测井,或者即使有了新技术测井仍然解决不了的情况也会存在,因此我们要进一步根据有限的测井资料开展研究,解决问题,能谱测井可以给我们提供一个间接识别低电阻油气层的方法,它可以通过分析粘土矿物的成分与含量来解决这类问题。For a long time,identification of low resistivity reservoirs has always been a problem of well logging interpretation,for the normal hydrocarbon reservoir resistivity curve values are higher than that of water layer,but some lower than water layer,even lower than shale.In recent years introduction of new technologies,such as nuclear magnetic resonance(NMR) and array induction logging method,has solved some problems,but there are still some unsolved problems without new logging technology or even with the new logging technology.We should carry out further researches according to the limited logging data to solve the problem.Spectrum logging can provide us an indirect identification method of low-resistivity oil layer,which can solve this kind of problems through analysis of the components and content of clay minerals.
