20世纪90年代核测井进展

通过对国内外1990－1999年间发表的240多篇有关放射性测井方面论文的分析，综述了20世纪90年代核测井的发展概况，重点介绍了核孔隙度测井系列，脉冲中子时间谱测井，脉冲中子伽马能谱测井，放射性同位素示踪测井以及核测井计算机数值模拟技术等国家内外研究发展热点的主要进展，人为，对核辐射信息作空间一时间－能量综合采集和分析的方法和仪器处在当前研究前沿，以测量精确度为核心，主攻复杂条件测井和生产测井，原始测量数据采集处理方法和解释方法创新以及计算机数值模拟技术开发和应用等仍将是今后一段时期中核测井的发展重点，此外，国内外还应继续狠抓核测井仪的硬件质量，并提高对其计量器具属性的重视程度。

Advances of Nuclear Well Logging in 1990s

Having surveyed 240 articles presented in 1990～1999， this review summarizes the main advances in nuclear well logging (NWL) in 1990s. It stresses on domestic and overseas“hot points” of research and development, such as nuclear porosity logging series, pulsed neutron time spectrum logging, pulsed neutron gamma energy spectrum logging, radioactive tracer logging, as well as the computerized numerical simulation technique applied in NWL. Methodologies and tools,which synthetically acquire and process the space-time-energy data of radioactive field, are presently at the front of research and development. Mainly attacking the logging in complex conditions and production logging while aiming at accuracy and precision of measurement as the key target, the main growing points of NWL in the near future keep on being as follows： methodological creation of raw data acquiring and processing and log analyzing, as well as development and application of computerized numerical simulation technique. In addition, attention to the metrological property of NWL tools should be emphasized greatly, while the quality of hardware of domestic NWL tools should be enhanced continuously． 40 pieces of references are enclosed.
