摘要
面对日益复杂的勘探对象,一维T_2谱核磁共振测井技术在流体识别中面临越来越多的困难,测井学家将二维核磁共振波谱技术引入核磁共振测井领域,创造出D-T_2二维核磁共振测井技术。本文对D-T_2二维核磁共振测井技术的发展现状做一综述,简述了二维核磁共振波谱学原理,介绍了D-T_2二维核磁共振基本原理,列举了三种常用的D-T_2二维核磁共振测井采集序列,展示了两个D-T_2测井实例。D-T_2二维核磁共振测井的出现,实现了从D-T_2二维谱中快速、精确区分油气水,为储层精细测井评价提供了新工具。
Faced with an increasingly complex exploration target,one-dimensional T_2 spectrum NMR logging technology is facing more and more difficulties in fluid identification.Therefore two-dimensional NMR spectroscopy technology is introduced into the field of NMR logging by well logging scientists, which creates D-T_2 two-dimensional NMR logging technology.In this paper,the development status of D-T_2 two-dimensional NMR logging technology is reviewed,the principle of two-dimensional NMR spectroscopy is outlined,the basic principle of D-T_2 two-dimensional NMR is introduced, three common acquisition sequences of D-T_2 two-dimensional NMR logging are cited,two examples of D-T_2 two-dimensional NMR logging are showed.The application of D-T_2 two-dimensional NMR logging achieves a rapid and precise distinction between water and gas from D-T_2 two-dimensional spectra,which provides a new tool for the reservoir logging evaluation.
