摘　　要：从地磁场核磁共振测井到Ｉｎｓｉｄｅ－ｏｕｔ概念的提出，再到磁共振成像测井，全面回顾了有关的早期历史。根据测井油气评价的基本问题以及常规测井解释所存在的缺陷，深入分析了核磁共振测井对产液性质、产层性质、油藏性质测井评价的贡献。核磁共振测井不是原有方法的简单改进，它以全新的原理，提供一套全新的信息，通过全新的响应关系，对测井油气资源评价，包括层位、储量、产能以及增产措施与效果评价等问题，提供全新的解答。最后，指出了核磁共振测井可能的发展方向。Early stories of NMR logging development,from earth field NMR to“inside out”concept,then to magnetic resonance imaging logging,are introduced.Based on the fundamentals of well logging formation evaluation and disadvantages of conventional logging response,the contributions of NMR logging to fluids typing,pay zone evaluation and reservoir description are analyzed.NMR logging is not a simple modification of existing conventional logging.It exploits a new principle,acquires a set of new information,and uses new response relations,then provides new answers to logging formation evaluation problems such as pay zone positioning,reserve calculation,and producibility. Finally,future developments of NMR logging are discussed.
