存储式过钻杆测井技术的优选与应用

Optimum Selection and Application of Storage Drill Pipe Logging Technology

复杂井的测井施工难度大,常规电缆测井和湿接头测井很难将仪器下放到井底,存储式测井技术可以完成复杂井测井任务,目前国内外存储式测井技术采用机械释放、数控释放和电缆释放方式将仪器从保护套中释放出来,针对不同的复杂井况,采取与其对应的释放方式,对于复杂直井采用电缆释放式,对于复杂水平井采用机械释放式,对于无钻机测井采用数控式,优选的释放方式能够提高测井成功率,降低作业风险和仪器损伤,减少占井时间。

The logging operation of complex wells is very difficult. It is difficult for conventional cable logging and wet joint logging to lower the tool to the bottom of wells. Storage logging technology can accomplish complex well logging tasks. At present, the storage logging technology at home and abroad uses mechanical release,numerical control release and cable release to release the instrument from the protective jacket. For different complex well conditions,corresponding release methods are adopted. For drillless logging,numerical control is adopted,and the optimal release mode can improve the logging success rate. Reduce operation risk and instrument damage,reduce well occupying time.
