摘　　要：地球化学录井可以在随钻过程中对烃源岩有效性和储集层流体进行评价,为油气水解释和石油地质研究提供基础数据,但现有分析过程相对粗糙,评价方法单一。本文从地球化学原理分析入手,开展地球化学录井解释图谱对比研究。地球化学录井技术可分为岩石热解和热蒸发烃气相色谱两大技术体系,分别可形成大量解释参数和图谱,以比值交会为基础的解释图版应用较多,可进一步拓展数学模型法等拓展解释思路。Geochemical logging can evaluate the availability of source rocks and reservoir fluids while drilling,providing basic data for oil,gas and water interpretation and petroleum geology research.However,the existing analysis process is relatively crude and the evaluation method is single.This paper starts with the analysis of geochemical principle and carries out the comparative study of geochemical logging interpretation map.Geochemical logging technology can be divided into two technical systems,rock pyrolysis and thermal evaporation hydrocarbon meteorological chromatography,which can form a large number of interpretation parameters and graphs respectively.The interpretation charts based on ratio cross section are widely used,which can further expand the interpretation ideas such as mathematical model method.
