油田放射性测井对环境和个人辐射剂量分析

放射性测井对环境和个人辐射剂量监测数据表明:个人受辐射伤害最大的是保管员,其次是仪器修理人员,然后是农民轮换工、司机、绞车工、操作工、主管领导、井口工人。保管员、仪器修理工、司机遭受辐射的剂量比较大,而在一线现场操作人员的个人辐射剂量水平反而都比较低,说明现场的个人防护措施得当。经过分析,确定了放射性测井施工中各岗位的安全操作时间,并针对个人防护存在的问题,提出了相应的改进措施和建议。

Analysis on Radiation Injury ofRadioactive Logging to Environment and Persons

The radiation doses of radioactive logging to the environment and person were detected. The results show that the first radiation injurer is the custodian, and the secondary one is the instrument repairman, and the following are the peasant of alternate operator, driver, winchman, operator, leader, and well-head operating personnel. The radiation doses of radioactive logging to custodian, instrument repairman and driver are greater than the doses to other personnel, which indicates the protection measures on site are feasible. The most proper operation times for different posts were determined. In term of personnel protection in oilfield, some feasible suggestions and modification measures are presented.
