摘　　要：围绕示踪剂验封技术思路、示踪剂筛选及用量、示踪剂投加、取样和检测,开展了示踪剂验封技术研究,创新出示踪剂验封法。该法施工检测简单易行,安全系数高,成本低,无污染,无作业占产,验封成功率高,工艺可靠性强。在双河油田应用32口油井,检测出封隔器密封失效井3口、未失效井29口,示踪剂验封成功率100%。示踪剂验封技术使封隔器密封可靠性判断有了新的依据,进一步提高了验封效果,有助于增进储层认识,减少油井盲目作业。Based on idea of sealing ability inspection using tracer,tracer selection and its dosage,its sampling and check,a technical study was carried out on sealing ability inspection using tracer,a method for sealing ability inspection using tracer was created innovatively.The method was easy operation,safety coefficient was high with low cost,without pollution and no accounting for production by operations,high success rate of inspecting seal ability,it had more reliability of the technology.The method is used in 32wells,there are 3wells of seal failure and it is successfully used in 29wells,the success rate is 100%.The method of inspecting seal ability by tracer provides a new basis for judging seal reliability of packer,it further enhances the effect of seal ability inspection,and beneficial for promoting the understanding of reservoirs to reduce blind operation of wells.
