卡销源室是我队测井人员在工业学大庆的群众运动中,大搞技术革新的情况下,在渭南仪器厂生产的放射性测井仪源室结构的基础上改进而成。原来源室与探管的连接是采用丝扣连接的,通过现场生产实践证明,采用丝扣连接有很多缺点,往往因丝扣磨损脱扣而造成放射源掉入孔内的严重事故,另外操作时间较长(装或卸一次源室需2分钟左右),使操作者受伽玛射线照射所接受的剂量较大。为了克服这些缺点,我队测井工人和技术人员通过反复试验,终于试制成功“卡销源室”。
Card lock source room is my team loggers in the industrialization of the mass movement in Daqing, vigorously technological innovation, the Weinan Instrument Factory production of radioactive logging tool source room structure based on an improvement. The original source chamber and probe connection is the use of threaded connections, through the field production practice has proved that the use of threaded connections have many shortcomings, often due to tripping wear and tear caused by radioactive sources fall into the hole within the serious accident, the other operation A long time (loading or unloading a source room for about 2 minutes), so that the operator by the gamma ray irradiation received a larger dose. In order to overcome these shortcomings, our team of logging workers and technicians finally trial-produced the “card lock source room” through trial and error.
