辽河油田经历40余年开发,大部分区块进入高含水期,水淹层问题是油田开发中面临的重要问题,应用测井技术提高水淹层的解释符合率是油田对测井的迫切要求。核磁共振测井作为识别流体的先进测井技术,其在水淹层解释中有着重要价值,综合应用核磁T2谱、差谱和移谱在水淹层的响应特征,可有效识别水淹层,评价水淹级别。
Liaohe Oilfield has been developing for more than 40 years and most of the blocks have entered the high water cut period. The problem of water flooded layer is an important issue in oilfield development. The application of well logging technology to improve the coincidence rate of water flooded layer interpretation is an urgent requirement for oil well logging. As an advanced logging fluid identification technology, NMR logging has important value in the interpretation of water flooded layer. The comprehensive application of NMR T2 spectrum, differential spectrum and shift spectrum response characteristics in the flooded layer can effectively identify the water flooded layer, Evaluation of flooding level.
