闪烁γ自动测井和综合测井在油田和煤田地质勘探中获得了广泛应用,但在铀矿地质勘探中应用的还比较少。随着铀矿地质勘探工作的发展和对铀矿化成矿规律综合研究的深入,特别是随着无岩芯和小口径钻探的推广,必须变目前单一的γ测井为多物性参数的综合测井,扩大研究的思路和范围,同时把测量方式由点测过渡到全自动连续记录。我们以小型的JBC-2型轻便自动测井仪为基础,在川北砂岩地区开展了闪烁γ自动测井和综合测井的试验工作;并对外单位的先进测井技术、轻型组合测井仪、超声成相测井仪和
Flashing gamma automatic logging and comprehensive logging have been widely used in the geological exploration of oilfields and coalfields, but are rarely used in geological exploration of uranium deposits. With the development of uranium prospecting and the comprehensive study of uranium metallogenesis, especially with the promotion of non-core and small-diameter drilling, it is necessary to change the single γ-logging to be a comprehensive multi-parameter test Well, to expand the research ideas and scope, at the same time the measurement mode transition from point to full automatic continuous recording. Based on the small JBC-2 portable automatic logging tool, we carried out the experiment of flashing gamma automatic logging and comprehensive logging in the sandstone area of North Sichuan. We also conducted advanced logging technology, light combined logging tools, Ultrasonic phase logging tools and
