当储层孔隙中同时存在油、气和水时,一维核磁共振测井难以准确判别孔隙中流体的性质.二维核磁共振能够测量横向弛豫时间、纵向弛豫时间、扩散系数、内部梯度场,充分利用了核磁共振的测量信息.介绍了二维核磁共振测井的基本方法,及二维核磁共振测井仪MR Scanner的工作原理和应用.二维核磁共振测井通过多种探测深度测量对比,得到了泥浆侵入剖面流体变化信息,提供更准确的储层流体性质信息.对长庆油田二维核磁测井应用实例进行了分析,测井解释结果与试油结论一致.

One-dimensional NMR (1D Nuclear Magnetic Resonance) technology can not identify the pore fluid accurately when oil, water and gas coexist in reservoir pores. 2D NMR logging adequately uses NMR information by measuring transverse relaxation time, longitudinal relaxation time, diffusion coefficient and internal gradient field. Introduced are the method of 2D NMR logging, the principle and application of 2D NMR logging tool--MR Scanner. The fluid changing data of mud invasion profile are obtained by contrast of 2D NMR measurements data at different depths, and this provides more accurate reservoir fluid property information. Analyzed are the case studies of 2D NMR logging in Changqing oilfield, and its interpretation results are in accord with the oil test conclusion.
