摘　　要：核测井中由自然伽马能谱测井仪获取的地层天然伽马能谱质量的优劣，关系到地面系统的解谱效果以及实测井的成败，而其核心部件探测器的线性问题将会直接影响伽马能谱的质量。通过分析仪器非线性原因，找出主要影响因素并对探测器的线性进行了改进，以此来提高自然伽马能谱测井仪的测井质量。The merits of the quality of natural gamma spectrum data by the natural gamma spectrum tool in nuclear logging is related to the effects of solution spectrum of ground systems and the success of measured wells. Then the apparatus of linear problems will directly affect the quality about the gamma spectrum. By analytical instruments nonlinear, the key factors are identified and linear of detector has been improved in order to improve the natural gamma spectrum data of the log quality.
