摘　　要：本文阐述了根据烃源岩的热演化阶段、不同温度段烃类的含量和油气全烃色谱指纹特征来早期判断地下烃类相态的地球化学方法,达到了在钻探过程中经济、快速地进行地下储集层中烃类相态的早期预测的目的。这一方法耗时少,花费低,而且所需的原始实验数据容易获得,判识精度较高。The geochemistry method identifying hydrocarbon phase state in the early stage is presented in the paper by thermal evolution stage of source rock, hydrocarbon content of different temperature rang and total hydrocarbon chromatography, in order to predict hydrocarbon phase state in reservoirs economically and quickly in the early stage. This method is characterized with lower time-consumption, lower cost, high accurate and easy acquisition of the raw data.
