| 摘 要： | 本文通过固体沥青、沥青砂岩及加入不同介质原油与稠油的加水密闭热压模拟实验,对比研究了海相原油与沥青的气体产率特征、生气潜力及其影响因素.结果表明原油与沥青的生气潜力除与岩性、演化程度有关外,还与其所含可溶有机质性质和组成等密切相关,H/C原子比越大,最大烃气产率越高,生烃气潜力越大.储集岩或运移途径岩石中的原油与沥青,当其再次达到成熟-高成熟阶段时,可以作为新的轻质油气或者天然气源岩.

| Abstract: | With the hydrous thermal pressure simulation experiments of the solid bitumen,bitumen limestone,bitumen sandstone and oil with different media,the experiment result of the characteristic of gas-generating factor,gas-generation potentiality and their affecting factor of the marine crude oil and bitumen was correlated.The experiment results indicated that the gas-generation potentiality of marine crude oil and bitumen not only related to the lithology and the evolution grade but also to the abundance and component of the soluble organism.The most hydrocarbon gas generating factor heightens with the atomic ratio of hydrogen to carbon.The reservoir rock or the rocks in migration path are the new source of light oil or natural gas when they reach to matured-high matured stages. |

| Keywords: | crude oil and bitumen gas-generation potentiality characteristic of gas-generating factor simulate experiment |
