摘要: 对我国油(气)田测井用放射源运输和使用管理情况开展了全面调查。目前全国共60余家测井源持有和使用单位,各单位共持有测井源约3 340枚,其中属于二类放射性物品的测井源约697枚。二类运输容器有126种型号,共697台。调查发现40%测井源存在超期服役;测井源运输容器大部分不合规,仅有22.5%的容器按法规要求备案;部分运输容器存在表面剂量率超出国家标准要求,高达标准限值的7倍;测井操作实践不规范等。针对上述问题,提出了相应建议。

Abstract: The data of the transportation and use of radioactive sources as well as their packages for well logging used in oil (gas) fields were collected. At present, there were more than 60 organizations in China that use well logging sources. There were approximately 3 340 well logging sources, in which 697 sources belong to Class II radioactive materials. And there were 126 types of packaging for those 697 sources. Investigation has found that 40% of the well logging sources have expired service. Only 22.5% of packaging had been registered. The surface doses of some packages approach 7 times of the limits specified by national standard. The well logging operations were also not quite standardized. Suggestions were put forward to these problems.

Key words: well logging, radioactive sources, transport
