Abstract

The results of the studies of organic matter in the rocks of the Bazhenov Formation in the territory of the Frolov oil and gas region of the West Siberian basin are presented. The maceral composition of the sediments is represented by bituminite and alginite, redeposited vitrinite, as well as bioclasts: onychites and calcespheres organic matter. The investigation was focused on bioclasts. Their coal petrographic characteristics and change in the process of catagenesis are described; qualitative parameters to access the degree of bioclast maturity are established; as well, an initial formula for converting the onychite reflectance to the equivalent of vitrinite reflectance is proposed.

弗罗洛夫油气区巴热诺夫组岩石还原过程中生物碎屑的演化

摘要

介绍了西西伯利亚盆地弗罗洛夫油气区巴热诺夫组岩石有机质的研究结果。沉积物的显微成分以烟煤和藻岩、再沉积镜质体以及生物碎屑：甲石和钙球有机质为代表。调查的重点是生物碎屑。描述了它们的煤岩学特征及其在还原过程中的变化；建立了衡量生物碎屑成熟度的定性参数；此外，还提出了将甲石反射率转换为镜质体反射率的初始公式。
