摘　　要：佟广新，等．吸水剖面测井同位素两次释放新工艺．测井技术，１９９７，２１（４）：２９２～２９６同位素测井一直存在两个重要的技术问题：同位素测井的粘污问题和同一注水井各渗透层吸水量相差较大的测试问题。吸水剖面只能做定性解释。采用一口井释放两次同位素的施工新工艺，用两次释放同位素各测得的动态曲线和稳态曲线叠合，分别用差值法、均值法可以达到对吸水剖面的定量解释。There are always two important technical problems in isotope tracer logging: One is the contamination which the isotopic logging causes; the other is how to test the same water injection well in which exists much difference in the capacity of water absorption in various formations. With the old technique, only qualitative interpretation could be made for injection profile. And now a new technique is adopted which releases isotope twice in the same well. A “dynamic curve” obtained from the second isotope tracer log overlaies with a “stable curve” obtained from the first tracer log. The seperation between the two curves corresponding to the permeable zones and the mean value of the seperation between the dynamic curve and the reference line are used for the quantitative interpretation of the injection profile.
