摘要
记述了塔里木盆地 44个原油样品中发现的孢子花粉化石 83属 1 6 3种 ;基于原油孢粉集合组成的研究 ,探讨了塔北、库车、喀什和叶城四个含油区油源岩的时代和层位 ;并根据孢粉化石的颜色鉴定了油源岩的成熟度。研究结果表明 ,研究区石炭系、三叠系和侏罗系油源岩都是成熟的油源岩。此外 。
One hundred sixty three species of fossil spores and pollen referred to 83 genera extracted from 44 crude oil samples collected from the Tarim Basin were recorded. Based on the investigations of the characteristics of the petroleum sporo pollen assemblages, the geological ages and formations of the petroleum source rocks of the North Tarim, Kuqa, Kashi, and Yecheng petroliferous regions were discussed. According to the colors of spore and pollen fossils, the organic thermal maturity of the petroleum source rocks of the mentioned petroliferous regions was identified. The results of this study indicate that the Carboniferous, the Triassic, and the Jurassic petroleum source rocks all belong to mature phase of liquid petroleum generation. In addition, the method used to extract fossil spores, pollen, and algae from crude oils was introduced in detail in this paper.
