本文介绍油田测井用锡-铟(~(113)Sn-~(113m)In)发生器装置的实验室考查研究及其在油田生产井产液剖面测量中的应用。发生器出厂时~(113)Sn的装置不少于1.11×10~9Bq;在有效使用期4个月内,~(113m)In的淋洗效率>70%,冼脱液浓度约37×10~8Bq/20ml可满足生产井的示踪流量测定;储存温度在0℃以上,工作温度范围4-45℃.可耐三级公路颠簸.本工作的野外用实验装置具有以下特点:能牢固地装配在工程车上,便于运送到现场使用,可以在油矿井场就地淋洗取得~(113m)In供石油生产井产液流量的测量,操作方便、不污染环境,装置表面照射量率符合国家标准,即年剂量当量不高于国标GB-4792-84中规定的公众中个人的剂量限值(全身为5mSv)。
This paper introduces the laboratory investigation of tin-indium (~ (113) Sn- ~ (113m) In) generator for oilfield logging and its application in the production profile measurement of oilfield production wells. The generator shipped with ~ (113) Sn was not less than 1.11 × 10 ~ 9Bq. Within 4 months of effective use, ~ (113m) In had a leaching efficiency of> 70% and a concentration of about 37 × 10 ~ 8Bq / 20ml to meet the production well tracer flow measurement; storage temperature above 0 ℃, the working temperature range of 4-45 ℃ .To third grade road bumpy.This work field experiment device has the following characteristics: can be firmly Assembled in the engineering truck, easy to transport to the site to use, you can get in the oil field leaching ~ (113m) In for oil production wells liquid flow measurement, easy to operate, do not pollute the environment, the device surface dose rate in line with National standard, that is, the equivalent dose per year is not higher than the national individual in the national standard GB-4792-84 dose limits (body 5mSv).
