| 摘 要： | 通过含水原油样品Ｔ１／Ｔ２一次性测量实验数据的频域２维洗白叠迹图分析，测定了样品的油水相对含量、化学位移及各自的弛豫成份，得出了原油和水两相之间没有化学交换及自旋交换的结论，为进一步研究原油和水在储油岩芯孔隙中时的ＮＭＲ弛豫行为提供了参考依据，对有化学位移的核自旋系统，这种弛豫成份分析方法具有一定的优越性．ＮＭＲ弛豫方法测定原油中的含水量在石油开采和计量中也有一定的实用价值．

| Abstract: | Proton NMR two dimensional timedomain data are collected based on the inversionrecovery technique.For multiphase systems,the two dimensional frequencydomain analysis shows many advantages.In this paper,The determination of nuclear magnetic relaxation parameters and the relative compoment of monophase from two dimensional frequencydomain data of the multiphase system are discussed in detail.Three watercontaining crude oil samples are given as examples. |
