通过对新旧标注方法的工作原理对比,总结对比新旧标定法特点。电缆标定仪就是以新的方法为理论依据研制产生的,其原理是依据标准井井下套管序列为参考深度对测井电缆进行加注磁性记号。在新科技不断发展的情况下,新技术在测井校深领域的应用前景会越来越广阔。 By comparing the working principle of the old and new annotation methods, the features of the old and new calibration methods are compared and contrasted. Cable calibrator is based on a new method developed for the theory, the principle is based on the standard well casing sequence for the reference depth of the logging cable magnetic markings. With the development of new technology, the application prospect of new technology in the field of well logging will be more and more broad.
