套管井自然伽马能谱测井资料的应用分析

自然伽马能谱测井是一种新的测井方法。该文主要针对胜利油田的多个油区的套管井自然伽马能谱测井资料的应用实例进行了分析，指出它在开发过程中对研究管外窜槽、注水层的吸水量、判断水淹层和划分水淹级别、划分储集层和判断储集层性质、划分油层中的泥岩夹层、确定泥质含量及粘土类型等方面的重要作用。在综合其它测井方法后，能对研究储层变化、寻找剩余油分布等提供重要的手段。

Application and analysis of natural gamma-ray spectral logs in cased well

Natural gamma ray spectral log is a new type of well logging method.This paper analyzes the application cases of the natural gamma ray spectral log data in cased well in several oil regions in Shengli oil field. The significance of these data during oil field development is described in the following research areas:channeling outside casing.amount of water intake in water-injection zone,determination of watered-out zone and classification of the watered-out degree,division of reservoir,and determination of reservoir properties, determination of the mudstone intercalation,clay contents and clay type. Combined with other data , they provide important means in the research of reservoir change and distribution of remaining oil saturation.
