摘要
铀是我国重要的战略资源,砂岩型铀矿测井技术是高效的勘查手段。总结了自然γ测井和铀裂变瞬发中子测井技术在砂岩型铀矿测井方面的关键技术进展和问题。对自然γ测井主要围绕自动稳谱技术、死时间修正技术以及γ能谱测井解谱技术等方面进行了分析和总结。对铀裂变瞬发中子测井的技术难题以及优势方法应用进行了介绍。结果表明,自然γ测井技术近年研究方向集中在死时间修正和解谱技术,铀裂变瞬发中子测井虽有一定的技术优势和发展前景,但由于其测井效率低的问题未被解决,目前主要辅助自然γ测井技术进行“铀-镭-氡”平衡系数求取。
Uranium is an important strategic resource in China,and sandstone-type uranium logging technology is an efficient exploration method.The key technical progress and problems of naturalγlogging and uranium prompt fission neutron logging technology in sandstone uranium logging are summarized.The naturalγlogging mainly focuses on automatic stabilization technology,dead time correction technology andγenergy spectrum logging and demytration technology.The technical difficulties of uranium prompt fission neutron logging and the application of advantageous methods are introduced.The results show that the research direction of naturalγlogging technology in recent years has focused on dead time correction and spectral technology,and although uranium prompt fission neutron logging has certain technical advantages and development prospects,due to its low logging efficiency,it is mainly assisted by naturalγlogging technology to obtain the"uranium-radium-radon"balance coefficient.
