摘　　要：针对试井解释结果具有多解性,且解释结论的可靠性评价没有专门的技术方法这一问题,采用试井解释和岩心图版对比的方法来检验试井解释结论是否合理。根据相对渗透率试验数据建立了有效渗透率和绝对渗透率之间的关系式,应用该关系式把试井解释的有效渗透率校正到绝对渗透率并与岩心分析校正后的绝对渗透率进行对比,可对试井解释的有效渗透率是否合理做出准确地判断。Since there is the ambiguity of well test interpretation and no special technique method for the reliability evaluation of interpreted result,we try to use the well test interpretation and core permeability pattern to examine whether or not the integrated result is reasonable.The relational expression between effective permeability and absolute permeability is deduced by the relative permeability of test data.Then the effective permeability is corrected to the absolute permeability by means of the relational expression.Finally,we compare two kinds of permeability to make the accurate judgment for the effective permeability of the well test interpretation.
