摘　　要：本文介绍了一种新型的放射性同位素示踪测井方法。用^(113)Sn—^(113m)In 发生器洗脱液中的^(113m)In与各种载体配制成多种放射性示踪剂,用其可测试油田生产井产液剖面,注水井吸水剖面和气田生产井产气剖面。本方法具有放射性核纯度高(>99.9%)、核素半衰期短(99.5min)、无污染、无毒性、在井场临时生成,现用现取,操作简单、使用安全,测井结果准确,施工效率高等优点。A novel radioisotope tracer log using ^(113m)In is presented in this paper.Various kinds of radio- tracer are made up with ^(113m)In in the eluate of ^(113)Sn—^(113m)In generator and varied carriers.They can be used for production profiles of oil and gas producing wells and injection profiles.^(113m)In can be generated constantly on the well site when it is needed.It is easy to generate and safe to use.The eluate is of high radionuclidic purity(>99.9%)and short half-life(99.5min).It is very effective in well logging.And there is no poisonous and radioactive contamination problem to the environ- ment.
