摘要: 测井电缆是测井获取地层信息过程中重要的配套设备,一旦落井后,打捞难度大且处理周期长.结合塔河油田近年来电缆落井处理情况,分析了电缆落井原因及落井后电缆在井中的状态.研究了目前工区使用的钻具打捞和电缆打捞方法,并结合实例对工具使用及改进、打捞方法、异常情况处理进行了阐述.Abstract: 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.
