摘　　要：理论和试验研究表明,三孔隙度与含气饱和度存在密切关系。通过计算得到的三孔隙度差值和比值能较好地反应气、水层。采用反映气水变化的电阻率与孔隙度大小的声波测井值建立气层和水层的判断标准线,进一步建立气、水指数图版能更为直观地反应工区致密砂岩气、水层。The research from the theory and experiment shows that there is a close relationship between the three porosities and gas saturation.The D-value and the ratio of the three porosities by calculation can reflect gas and water layer better.The acoustic logging value of the resistivity and porosity size reflected by gas and water changes is adopted to establish the judgment standard so as to to further establish the gas and water index chart for straightly demonstrating the tight sandstone gas and water layers in the working area.
