我国中、新生界陆相含油气盆地中几乎均有未成熟-低成熟石油,并呈现出东部分布广、中西部分布较少的特点。低熟油气的研究与勘探具有非常重要的理论意义和经济价值。目前国内发现的低熟油气类型多样,这些未熟—低熟油气在族组成、镜质体反射率、饱和烃、芳烃、卟啉、同位素等方面具备一定的共同特征使得其与成熟油气相区别。未熟—低熟油气的成烃机理除了较多提到的早期生烃和早期降解模式外,火山活动及地幔流体在未熟—低熟油气生成中具有作用。未熟-低熟油气的研究尚存在一些问题,认为应将未熟-低熟油作为一个独立研究领域进行深入的有针对性的研究。
In China, there are almost immature-low mature oil in the Cenozoic continental oil and gas petroliferous basins, showing the features of wide distribution in the east and few in the central and western regions. Research and exploration of low-mature oil and gas have very important theoretical significance and economic value. At present, the types of low-mature oil and gas discovered in China are diverse. These immature and low-mature oil and gas have certain common features in terms of family composition, vitrinite reflectance, saturated hydrocarbon, aromatics, porphyrin and isotope, which distinguish them from mature oil and gas. Hydrocarbon Generation Mechanisms of Unripe-Low-Mature Oil and Gas In addition to the more-mentioned earlier models of hydrocarbon generation and early degradation, volcanic activity and mantle fluid play a role in the immature-low-maturity oil and gas generation. Unripe - low oil and gas research there are still some problems, that should be immature - low oil as an independent field of research conducted in-depth targeted.
