摘　　要：测井数据对测井作业的开展至关重要,故中选择测井数据为研究样本,从三个方面入手,浅析了其深度校正方法,首先对电缆的拉伸与校正方法进行了分析,其次对速度的校正方法进行了分析;最后对相对深度的校正方法进行了分析。其中主要介绍了三种方法,第一种为深度控制曲线校正法;第二种为相关对比校正法;第三种为地层层序分析校正法。通过分析发现,上述这几种方法均比较可靠。另外,通过深入分析也对这几种方法的具体优缺点进行了明确,这对我国进一步强化测井工作效能有着一定的理论和实际意义。Logging data is crucial for conducting logging operations,Therefore,in this article,logging data is selected as the research sample,Starting from three aspects,the depth correction method was analyzed,Firstly,the stretching and correction methods of cables were analyzed.Secondly,the correction methods for speed were analyzed.Finally,the correction methods for relative depth were analyzed,Three methods are mainly introduced,The first method is depth control curve correction;The second method is the correlation comparison correction method;The third method is the correction method for stratigraphic sequence analysis.Through analysis,it was found that,The above methods are all relatively reliable.In addition,the specific advantages and disadvantages of these methods have been clarified through in-depth analysis,This has certain theoretical and practical significance for further strengthening the efficiency of logging work in China.
