Formally, a Set consists of one or more Objects of the same type, * preceded by a Template. */ QPtrList<_componentObject> objLst; }; struct _IFLR { QString ddr; unsigned char modifier; unsigned int numFrame; QValueList frameNOs; QValueList sizeSescriptors; QValueList fdata; QStringList sdata; }; 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"; • "REPRESENTATION-CODE"; • "SPECIFICATION"; • "UNIT-SYMBOL"; • "BASE-DICTIONARY"; • "IDENTIFIER"; • "LEXICON"; • "OPTION"; • "ORIGIN-TRANSLATION"; • "DLIS-CONTEXT"; • "WELLBORE-PATH-DATUM"; • "MESSAGE"; 1．5.2 每种公用类型EFLR可以转换为相关信息的Objects.每种类型EFLR为同种Object.其中类型_EFLR->set->type是唯一的。 1．5.3 IFLR根据DDR与FRAME OBJECTS中的某个Object相关联，其中IFLR中的每帧数据由多少个CHANNEL在FRAME Object中已经列出，每个CHANNEL的详细说明在CHANNEL OBJECTS中的某个Object相对应。所以在帧数据中每个通道的数据相关属性我们都可以得到。 1．5.4 每个通道表示一种属性的测井记录，它的测井数据记录在帧数据中，每帧数据是某个采样点（一般指某个深度）的水平方向测试的数据。有些测井曲线的数据在一个采样点为一个，有的为很多个，例如Image Data. 1．5.5 每个通道的测井属性和名字都可以在CHANNEL中找到，DLIS没有制定某种曲线的标准，只是表示任意测井数据的记录方法。 1．5.6 我们可以扫描Logical File得到所有EFLRs，从而得到所有测井数据列表。
