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。
This paper describes the geochemical methods of early judgment of the phase state of underground hydrocarbons based on the thermal evolution stages of hydrocarbon source rocks, the content of hydrocarbons in different temperature ranges and the fingerprints of hydrocarbon-based hydrocarbon, which achieves the economic and rapid progress in the drilling process The purpose of early prediction of hydrocarbon phase in underground reservoirs. This method is less time-consuming and low-cost, and the original experimental data needed are easy to obtain, and the accuracy of identification is high.
