摘　　要：原油裂解程度反映了原油在地质体中经历高演化阶段后向天然气转变的程度。定量表征原油裂解程度,可为原油裂解气资源量的评价提供重要依据。本文在模拟实验研究的基础上,综合分析讨论了原油热裂解过程中化学组分的变化特征,包括化合物组成和浓度的变化,这些变化特征是原油裂解程度量化描述的基础。因此,可建立模拟实验过程中原油裂解程度与变化特征参数之间的定量关系,将这种定量关系应用于塔里木盆地台盆区海相原油研究,从而为研究区海相原油裂解程度的研究提供一种参考方法和标准。The degree of crude oil cracking reflects the conversion from crude oil to natural gas during high evolution in the geologic body. Therefore, quantitatively characterizing crude oil cracking can provide an important basis for the evaluation of oil-cracked gas resource. Based on the simulated experiment study, the variation characteristics of chemical components, including compound composition and concentration, are comprehensively analyzed and discussed. These characteristics are the base of quantitative description on crude oil cracking. Consequently, quantitative relationships between crude oil cracking and various parameters can be established through the simulated experiment, and are applied into the study of marine oils in the platfoml region of the Tarim basin, which will provide a reference method and standard for the study of crude oil cracking in this area.
