摘　　要：大庆萨尔图油田一些分层注入井的油管口袋浅,传统注入剖面五参数组合测井经常不能录取到下部所有层位的资料。为此采取多项措施:制定了洗井规范;改进了组合测井仪结构,把过芯加重杆和伽马磁性定位短接分别设计到仪器串上部和下部,伽马探头到仪器底端距离缩短到0.3 m;测井施工中,采取先挂接空释放器测量基线、再挂接装同位素释放器的测井工艺,确保了伽马基线的准确性。试验表明,技术改进大幅提高了层位资料采集率。研究成果为浅口袋井注入剖面测井提供了技术保障。Some layered injection wells in Daqing Saertu oilfield have shallow tubing pockets,which causes traditional five-parameter combination logging of injection profile often fails to record complete data for all lower layers.To solve this problem,many improvements are carried out.A well flushing standard is revised.The distance between gamma-ray detector and the bottom end is shortened to 0.3 m by redesigning the weight bar and the GR/CCL cartridge to the upper part and lower part of the tool string,respectively.Accuracy of GR baseline is ensured by the logging process of attaching an empty isotopic-tracer release device.Field tests have shown that these technical achievements have greatly increased the acquisition rate of layer data and provided technological support for injection profile logging for shallow pocket wells.
