摘要
核磁测并从提出到商业化经历了近半个世纪的漫长过程。目前，世界上能够提供核磁测井服务的主要有俄罗斯以及Ｓｃｈｌｕｍｂｅｒｇｅｒ和ＮＵＭＡＲ公司。在技术方案上，既有基于“预极化－地磁场自由进动测量”的初始方案，也有利用Ｉｎｓｉｄｅ－ｏｕｔ概念和偶极梯度场对自旋回波串进行观测的新方法。未来的核磁测井正朝着多核、多频、可组合，以及提高测速、增加探测深度、改善纵向分辨能力的方向发展。回顾了核磁测井技术的发展过程，对比当前国际上已有的３种核磁测井技术方案，对如何发展我国的核磁测井技术提出了一些建议。
It took about half century to commercialize nuclear magnetism logging (NML) proposed in 1991.At present, three types of NMIL over the world are available,i.e.f the Russia's NML based on the earth magnetic field, Schlumberger's CMR, and NUMAR's MRIL.The trends of development in NML will be toward multi-nuclei, multifrequency,eomposite,and higher logging speed, deeper depth of investigation, and higher vertical resolution.The procedure of development NML is reviewed, logging technologies available today are compared to put forth some proposals to develop NML in China.
