辽河油田开发已近40年,水淹层问题一直是油田开发调整中重要的问题。水淹层解释符合率决定油田开发成本及油田调整的经济效果。特别是稠油水淹常规测井认识难度较大,核磁共振测井技术在辽河油田稠油水淹层解释评价中得到了广泛的应用,本文对其中的一些核磁共振测井应用实例进行了介绍分析。
Liaohe Oilfield has been developed for nearly 40 years. The problem of flooded layer has always been an important issue in the development and adjustment of oilfields. The interpretation of coincidence rate of water flooded layer determines the economic development cost of oilfield and the adjustment of oilfield. In particular, conventional logging with heavy oil flooding is notoriously difficult to recognize. NMR logging technology has been widely used in the interpretation and evaluation of heavy oil flooded layers in Liaohe Oilfield. Some examples of NMR logging applications are introduced in this paper.
