电缆测井资料的相关对比已成为沉积盆地地层解释的一项基本工作。这种工作方法通常包括用肉眼对比各种测井曲线,即利用某口井数字采样数据得到的曲线与另一口或更多邻井的相应曲线进行对比。相关对比开始主要用于评价地下岩体的横向展布。然而,这种对比过程具有相当大的主观性,常遇到目力难以辨别的困难,干扰了相关对比工作。例如,利用众多测井曲线对比判别非地层噪声、局部地层走向和区域地层走向的情况。各井地层层厚的变化或数据采集的差异导致了这些问题的产生。在分析处理这些问题时,相关对比还要受到井的数量和井
Correlation of cable logging data has become a basic explanation for the formation of sedimentary basins. This method of work typically involves comparing the various well logs with the naked eye, using a curve derived from the digitally sampled data from one well to the corresponding curve from another or more adjacent wells. The correlation contrast is mainly used to evaluate the horizontal distribution of underground rock mass. However, this process of comparison has considerable subjectivity and often encounters difficulties that are difficult to discern with eyesight, interfering with the comparative work. For example, a number of well logging curves are used to compare non-formation noise, local formation strike and regional formation strike. Changes in the formation thickness of various wells or data collection differences lead to the emergence of these problems. In analyzing and dealing with these issues, the correlation is also affected by the number of wells and wells
