摘要

摘要介绍了西西伯利亚盆地弗罗洛夫油气区巴热诺夫地层岩石中有机物的研究结果。沉积物的主要成分是沥青质和藻石、再沉积矾土以及生物碎屑岩：缟玛瑙和钙钛矿有机物。调查的重点是生物碎屑岩。描述了它们的煤岩相特征和在成岩过程中的变化；确定了获得生物碎屑成熟度的定性参数；还提出了将缟玛瑙反射率转换为等效矾土反射率的初始公式。

The Evolution of Bioclasts during Catagenesis in Rocks of the Bazhenov Formation in the Territory of the Frolov Oil and Gas Region

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.
