用同位素（113）~In测吸水剖面 减少放射性污染

放射性同位素示踪法测吸水剖面工艺在油田已应用很久了。吉林油田应用低毒性同位素（１１３）￣Ｉｎ测吸水剖面工艺，较好地解决了安全与环境污染问题。叙述了（１１３）￣Ｉｎ的产生原理，在吉林油田的试验应用以及使用（１１３）￣Ｉｎ测吸水剖面对环境的影响等。对从事油田测井的工程技术人员有一定的借鉴、指导作用。

Measuring Water Entry Profile with Isotope (113)￣In to Reduce Radioactive Pollution

Radioisotopic tracer technology measuring water entry profile has been used in oil fields for a long time. Application of low toxicity radioisotope113)￣In mea-suring water entry profile to Jilin Oil Field has satisfactorily resolved safety and environ-mental pollution problem. This paper gives an account of the generation principle of (113)In,its test applied to Jilin Oil Field and the effect of using (113)￣In to measure water entry profile on the environment.The engineering personnel engaged in well logging can draw on certain experience and directive function from this technology
