基于测井系列校正的趋势面分析法标准化研究

对测井资料进行标准化处理是地质精细解释的前提,不仅能提高测井资料的准确性,并且能保障测井解释精度。本文采用趋势面分析法对测井资料进行标准化。在进行第一次标准化处理时,由于研究区内新老井应用多种测井系列测量,出现了由测井系列差异引起的异常点。因此,将测井系列校正纳入标准化处理流程,即当工区开发历时较久、范围较大、测井系列较多时,在测井资料标准化之前必须先进行测井系列校正;提出了测井系列校正的方法,应用该方法对测井资料校正后,再进行第二次标准化处理。其结果检验表明,处理后的测井信息更加符合区域地质规律,证明该思路符合实际需求,能更加准确地完成区块测井资料的标准化,可以推广至全区及其它类似工区。

Normalization study of trend surface analysis based on logging series' correction

Logging data normalization is the premise of fine geological interpretation, which can not only improve the accuracy of logging data, but also can guarantee the accuracy of log interpretation. In this paper, trend surface analysis method is used for logging data normalization. During the first normalization, some outliers appeared due to different logging series used in the old and new wells. Therefore, this paper introduces the logging series'' correction to the normalization process, i.e. for working areas which are in large area having a long exploitation history and multi-logging series were used the correction of logging series must be done before the normalization. This paper proposes a logging series'' correction method. After logging data correction with this method begin the second normalization. Result of the normalization procession t shows that the processed logging information is more consistent with the law of the regional geological condition. Such normalization meets need of the actual situation and completes regional logging data normalization more accurately so it can be popularized to the whole region and other similar regions.
