纸质版测井曲线录入数据库方法探讨

Discussion on the Method for Inputing Database from Hardcopy of Log Curves

随着测井行业新的解释方法和计算模型的出现,以及测井行业资料库数字化转型新需求,老旧纸质版测井资料的重新利用就具有了较高的社会价值。为了实现纸质版测井资料的重新利用,则需要将纸质版测井曲线录入测井数据库,如何将扫描后的测井曲线录入专业的数据库成为纸质版测井资料重新利用的关键环节。以CLogDraw测井解释软件为例,对纸质版测井曲线录入,并进行探索和分析,总结出一套纸质版测井曲线录入CLogDraw数据库的方法。经过验证,该方法效率较高,提取的测井数据质量较高,与纸质曲线标注的数值之间偏差较小。

With the emergence of new interpretation methods and calculation models in logging industry,as well as the new need of digital transformation of logging industry database,reusing the old hardcopies of logging data has a higher social value.It is necessary to enter the paper log curves into the database for this goal.Therefore,it is the key factor for reusing paper log data to enter the log curves into the professional database.Taking CLogDraw log interpretation software as an example,this paper discusses and analyzes on inputing from log curves'hardcopy,and summarizes a set of methods that the log curve data entered into CLogDraw database.The method has been verified to be efficient,the quality of extracting logging data is high,and the deviation can be tolerated from those values noted on the hardcopy of log curves.
