摘　　要：给出识别低电阻率气层的３ 种方法： 空间模量差比值法、三孔隙度差值法、三孔隙度比值法。３ 种方法都消除了骨架和泥质的影响， 只突出反映了天然气的影响。通过实际资料的处理证实， 这３ 种方法能较好地指示天然气的存在。Three methods are presented to identify gas reservoir with lower resistivity They are called method of ratio of volume modulus difference, methods of difference of three kinds of porosity and method of ratio of three kinds of porosity All of them have eliminated the influence of matrix and shale and focused only on the effect of gas Practical process of data from two gas reservoirs with lower resistivity demonstrates that the methods proposed here have proved effective in showing the presence of gas
