SITAN Tension sub is used to prevent logging tools from blocking and getting stuck while the instrument is put down or lifted up in actual logging, and it is hard to tell whether cable or instrument gets stuck. If incorrect measures are taken, cable will be pulled off or instrument will drop into well. As a result, logging can’t finish smoothly and logging cost will be increased. It is of great significance for improving logging efficiency and lowering logging cost to judge whether cable or instrument gets stuck.
