摘　　要：气藏有效储层物性参数下限的确定是储集层评价和储量评估的基础。目前求取方法很多,包括测试法、统计分析法及经验公式法等,但每种方法都有自身适用的局限性,往往只是从某一个方面来反映储层的特征。因此,在实际应用时,应通过对储层物性下限影响因素的分析,利用多种方法,互相补充和验证,使得最终确定的物性下限能够综合反映储层的实际特征。另外,当同一地区地质条件差别很大时,可以根据对不同层位地质特征的研究制定相应的物性下限标准。In an effective gas reservoir, to determine the lower limit of physical-property parameters is a basis of reservoir evaluation and reserves estimation. There are many determining methods, including testing method, statistical analysis method and empirical formula method. But with its own limitations, every method just reflects reservoir characteristics by only one domain. So, to combine with these methods to compensate and testify mutually and to analyze the reasons which affect the lower limit are a best way. The finally determined lower limit can imply the actual reservoir characteristics. In addition, corresponding lower limit criteria should be drawn up based on the research on geological setting in different stratigraphic horizons if a big difference of geological conditions exists in the same area.
