| 摘 要： | 本文指出了低成熟石油概念和实际划分上的不统一和不规范,并给出了初步定义。另外,对低成熟石油的相关成烃母质进行了综述,在此基础上给出了低成熟成烃母质的定义,指出了低成熟石油成烃母质的多元性和油源的多源性特点,同时还指出低成熟石油是沉积有机质在地质埋藏过程中波动成烃连续模式之部分,其具有多元多源复合成烃行为和分阶段连续演化的特征。这些认识对正确评价含油气盆地中的低成熟油气资源具有重要意义。

| Abstract: | This paper points out that there are different concepts and division standards for low-maturity oil and its source rocks. The author discusses the division of low-maturity oil and its rocks, and attempts to define the low-maturity oil. In addition, hydrocarbon-generating material of the oil is reviewed and its definition is given. On that basis, the author points out that material of the oil generation has the multi-component characteristics and that the oils have the multi-source characteristics, and, further, it is indicated that oil formation is a process of multi-source and multi-component compounding and that the process is a part of the continuous hydrocarbon generation model of the damped cosine curve during the burial of sedimentary organic matter in geological time. All the above-mentioned ideas are very important for a correct evaluation of low-maturity oil-gas resources in petroliferous basins. |
