1．5说明

1．5.1每个EFLR是对某种类型的数据参数的表达，主要用来解释测井曲线的相关信息。公用的EFLR类型如下：

•"FILE-HEADER";

•"ORIGIN";

•"WELL-REFERENCE";

•"AXIS";

•"CHANNEL";

•"FRAME";

•"PATH";

•"CALIBRATION";

•"CALIBRATION-COEFFICIENT";

•"CALIBRATION-MEASUREMENT";

•"COMPUTATION";

•"EQUIPMENT";

•"GROUP";

•"PARAMETER";

•"PROCESS";

•"SPICE";

•"TOOL";

•"ZONE";

•"COMMENT";

•"UPDATE";

•"NO-FORMAT";

•"LONG-NAME";

•"ATTRIBUTE";

•"CODE";

•"EFLR";

•"IFLR";

•"OBJECT-TYPE";
