| 摘 要： | 本文通过模拟实验，结合塔里木盆地塔中北斜坡地区包括有机质成油、有机质成气及原油二次裂解成气在内的生烃剖面，说明原油二次裂解成气的门限深于干酪根初次裂解成气门限。原油二次裂解生成的天然气与干酪根初次裂解生成的天然气在组分特征和碳同位素特征上存在明显的差异。一些以原油二次裂解气为主要气源所形成气藏的实例，表明原油二次裂解气可以作为特殊的重要的天然气来源。

| Abstract: | It is considered based on the simulation tests and study of the hydrocarbon generating .sections related to oil generated from organic matter, gas from organic matter and gas from cracking of oil on the northern slope of the Tazhong Uplift in the Tarim Basin that the threshold of cracking gas from oil is deeper than the threshold of cracking gas from kerogen. The cracking gas from oil is very different from the cracking gas from kerogen in components and carbon isotopes. Some examples of gas fields, in which the gas was mainly derived from the secondary cracking of oil < show that the secondary cracking gas from oil is a special and important gas source. |
