On the basis of accurately calculating the parameters of formation water,the effects of these parameters on the effective porosities of rocks and the parameters of identifying gas reservoirs are emphatically analyzed.It is pointed out that in the strata containing salt-water,if the parameter values of pure water are used,the calculated effective porosities of the rocks and the calculated parameter values of identifying gas reservoir will be all reduced,which exerts a serious influence on the log recognition of gas reservoirs.

在准确计算地层水参数的基础上，着重分析这些参数对地层岩石有效孔隙度和气藏判识参数的影响，指出在含盐水的地层中，如果采用淡水参数值，其结果是使计算的岩石有效孔隙度和气藏识别参数值降低，严重地影响了气藏的测井识别。

Based on the above cases, aiming at the actuality and practical cases of low-resistivity oil/gas reservoir log interpretation and evaluation in this thesis, beginning with analysing the intrinsic characteristics and physical properties of low-resistivity oil/gas reservoirs, all kinds of formation origin and mechanism of low-resistivity oil/gas reservoirs are analysed systematically and a great many of examples are given. Then the low-resistivity oil/gas reservoirs are classified by their formation origin. By setting up all kinds of interpretation models of low-resistivity oil/gas reservoirs, discussing and studying the low-resistivity oil/gas reservoir interpretaion and prediction methods, a set of practicable and systematic well logging interpretation and evaluation methods is obtained.
