摘　　要：多臂井径成像测井仪是用来评价套损、检测射孔质量和套管状况的工程测井仪器,它采用磁记号校深,存在误差,影响测井质量。设计的井径伽马磁定位组合测井仪,采用伽马磁定位信号校深。文章介绍了组合测井仪的结构和工作原理、几种设计方案的比较、组合仪实现的技术关键及室内试验。The multi-arm caliper tool is used to estimate effect of casing damage, detect quality of the well perforation, and casing conditions. Depth correction making use of the magnetic mark affects logging quality,so the multi-arm caliper and gamma CCL combination tools use gamma CCL correct depth. A method of realizing instrument cluster is provided, and the structure and principle of tool, comparability of designed plan, the key to realize and indoor experiment are introduced.
