摘　　要：同位素沾污是影响放射性同位素示踪注水剖面测井的一个重要因素,采用“冷球”是减少同位素沾污的一种有效手段。过去采用的先下井释放“冷球”、再取出释放器装入同位素进行二次下井的测试方法增加了测试强度和费用。应用活塞式点火头装置以及有效的控制电路设计的双同位素释放器,一次下井就可以完成“冷球”和同位素的释放,提高了测试效率。The contamination of isotope is an important f ac tor that affects radioactivity isotope tracer injection profile logging, and the application of “GTP tiny ball without radioactivity” is an efficient way to e liminate contamination of isotope. The foretime testing method, downpassing th e release unit for releasing “the tiny ball” and then taking out the unit fo r filling isotope has increased intension and fee of test. The double isotope r elease unit applying pistonlike igniter and efficient control electric circu it can release “the tiny ball” and isotope at one pass trip, and enhances test ing efficiency.
