GPTMap如何计算非干层储层的物性参数和非均质性？油田现场经常需要计算孔渗饱参数和储层的非均质性，手工计算相当繁琐，利用GPTMap 软件，可以在“数据计算”下使用“计算分层界限储层参数”功能计算小层的孔渗饱参数；使用“计算储层非均质性”功能计算层间、层内非均质性。
操作步骤：（1）计算分层界限储层参数找到“数据”>“数据计算”>“计算分层界限储层参数”选择相应分层级别，把“干层”勾选上作为泥岩处理，点击确定在弹出的窗口中选择对应孔渗饱参数的计算方法。
厚度类型可选择测深或垂深，厚度数据可选择砂岩或有效。
目前软件均值算法支持加权平均、算数平均、几何平均、调和平均、最大值和厚度最大值五种计算方法。
也可以根据经验公式（可自定义设置）计算储层参数。
其中含油饱和度类型可选择百分比还是数值型。
计算结果存储在对应分层界限数据相应的孔隙度、渗透率、含油饱和度字段。
（2）计算储层非均质性找到“数据”>“数据计算”>“计算储层非均质性”选择相应分层级别，非均质性计算窗口包括层间非均质性计算和层内非均质性计算两个选项卡。
层内非均质性计算层内非均质性时，数据来源选择测井曲线时，可根据测井曲线中的渗透率曲线（PERM），按单砂层来计算渗透率级差、渗透率突进系数和变异系数。
计算完成即将纵向渗透率级差、纵向渗透率突进系数、纵向渗透率变异系数的计算结果存储在对应砂岩数据表和分层数据表相应的字段中。
层间非均质性计算层间非均质性时，数据来源选择“数据表”时，数据表或测井曲线，默认选择的是分层数据表中的渗透率字段参与公式计算；也可选择测井曲线，即渗透率曲线（PERM）。
计算时，纵向渗透率级差、纵向渗透率突进系数、纵向渗透率变异系数默认全选。
计算后，计算结果存储在对应分层界限数据相应的渗透率级差、纵向渗透率突进系数、纵向渗透率变异系数字段中。

Reservoir heterogeneity plays an important role on exploitation of oil and gas as well as redevelopment of the residual oil in old fields, so it has been the difficulty and emphasis of reservoir research. With most of continental clastic oil-gas fields entering into the middle or last period of development, the exploration and development of marine carbonate oil- gas fields become increasingly important. As the exploration of marine carbonate oil-gas fields in Tarim, Sichuan Basin made a major breakthrough; the research and evaluation of carbonate re-servoir heterogeneity become more and more important. Summarizing the research status, cha-racterization, research methods and so on of carbonate reservoir heterogeneity by referring to large amount of data and drawing lessons from clastic reservoir heterogeneity research tools, with the combination of multiple disciplines and the application of technology of reservoir geo-logic modeling, carbonate reservoir heterogeneity research will reach a new stage.KeywordsCarbonate Reservoir, Heterogeneity, Lorenz Curve, Geological Modeling for Reservoir碳酸盐岩储层非均质性研究现状及发展趋势孙跃东*，陈念，高雅，卢苑青，胡忠贵#*第一作者。
