摘　　要：探讨了^（１１３）Ｉｎ~ｍ－活性炭示踪剂作为测定注水井吸水剖面的可能性。研究了活性炭对￣（１１３）Ｉｎ~ｍ的吸附性能。观察了化学处理、粒度、介质ｐＨ值、吸附时间、吸附温度、液固比等物理化学条件对活性炭吸附^（１１３）Ｉｎ~ｍ性能的影响，从而获得用其测井的最佳吸附条件。用ＥＤＴＡ处理过的活性炭，对￣（１１３）Ｉｎ￣ｍ吸附率大于９０％。在１００℃的地下水中￣（１１３）Ｉｎ￣ｍ不脱附。用其测定了数百口井次注水井，成功率大于９５％。The possibility of using ￣(113)In￣m-Charcoal as a new radiotracer for determining the water intake pro-files in the water flooding wells is studied. The performance of charcoal to absorb ￣(113)In￣m: the effects ofthe chemistry treatment,size,pH in the medium,the time and temperature of absorption, ratio of char-coal to eluate and other chemical conditions on the performance are tested,from which the optimum ofthe well logging is obtained. The absorption of ￣(113)In￣m on EDTA-treated charcoal is more than 90%andthere is no desorption of ￣(113)In￣m in flushing water at 100℃. Hundreds of the water intake profiles in thewater flooding wells have been determined and more than 95%is successful.
