摘　　要：气体介质条件下的测井,是在井内为氮气(天然气)等气体介质状态下的一种测井方法。文中分析认为,井径、井斜、自然伽马(自然伽马能谱)、感应测井、井温测井、核磁共振测井是在气体介质条件下的有效测井系列;依据自然伽马确定岩性并根据感应曲线的差异,可以确定渗透层段,再利用井温曲线确定产气层段是可行的,为今后气体介质条件下测井系列的选择和解释打下了坚实的基础。Well-logging under the condition of gaseous media is just a well-logging measure under the circumstance of nitrogen(natural gas)within the well.This paper considers after an analysis that caliper logging,gamma-ray logging(spectral gamma-ray logging),induction logging,temperature logging and NMR logging belong to effective well logging under the condition of gaseous medium.Lithology may be determined by gammy ray.And then,permeable intervals can be confirmed by the lithology and the difference in induction curves.In addition,gas-producing intervals can be determined by well temperature curves.As a result,all the above-mentioned provide a firm basis for well-logging selection and well-logging interpretation under the condition of gaseous media.
