放射性源强磁打捞器的研制

Development on Radioactive Source Strong Magnetic Die

文章介绍了放射性源强磁打捞器的研制和试验。提出了给打捞主体配备探测器，根据目前测井所用放射性源，设计一种伽马射线探测器即可满足要求；并根据井眼条件（有无套管）等方面因素，对打捞主体的机械结构进行了合理设计。该打捞器经七口井的试验，取得了满意的效果。

Here in this paper the research and test works on radioactive source strong magnetic die were introduced. Also the concept that equipping the main body of the die with a Gammy-Ray detecter that designed according to current logging radioactive source could perfectlly meet the demands of fetching out process. A reasonable mechanical design of the main die body was given on the basis of considering every determining factors such as the bore hole condition(casing or not ). Satisfying result was obtained from experiments of the die on seven wells.
