摘　　要：自然伽玛测井仪主要用于随钻测井过程中探测地层中的放射性元素发出的伽玛射线,从而判断地层信息。文章介绍了随钻自然伽玛测井仪的响应模型建立。阐述了对仪器响应模型、点源响应、地层响应、井眼和泥浆等诸多因素对仪器测量误差的影响做分析研究。The natural gamma logging tool is mainly used to detect gamma ray formation of radioactive elements in the process of logging while drilling to judge stratigraphic information. This paper mainly introduces the response model of the natural gamma logging tool used in logging while drilling, focuses on the analysis and research of the response model, points source response, stratigraphic response etc. In addition, analyses and research the instrument measure error caused by hole and mud, and many other factors.
