Logging cable is an important matching tool in the process of obtaining strata information while logging. Once dropping well, fishing is very difficult and the processing cycle will be quite long. In recent years, according to the processing methods of lost cable in the Tahe Oilfield, the reasons for logging cable dropping and different states of logging cable in wells are analyzed. Combining with the techniques of drilling tool fishing and logging cable fishing in the current work areas, it states three dimensions: application and improvement of fishing tools, fishing method, abnormal condition.
