放射性测井为孔隙度测井系列不可缺少的重要方法.目前,各油田开展的放射性测井项目很多,特别是西安石油勘探仪器总厂生产的SJD-801仪器和83系列投放现场以后,使用放射源的次数和放射源的活度都比以往的老方法多了许多倍,这就给从事放射性测井的工作人员增加了照射剂量,带来了精神压力.为减少辐射对工作人员的危害,根据辐射防护最优化的原则使人体受到的辐射保持在尽可能低水平,我们设想了迷路铁轨式
Radioactive logging is an indispensable and important method for porosity logging series.At present, there are many radioactive logging projects in each oilfield, especially after the SJD-801 instrument and 83 series put on site of Xi’an Petroleum Exploration Instrument Factory are put into use, The number of sources and the activity of radioactive sources are many times higher than the old methods, which increased the exposure dose and mental stress to the staff engaged in radioactive logging.In order to reduce the harm of radiation to the staff, According to the principle of optimal radiation protection to keep the body’s radiation as low as possible, we have envisioned a lost track
