Abstract

Based on the study of core material, the lithological features of the deposits of the Kolgan formation of the Frasnian stage in the southwestern part of the East Orenburg arch uplift are considered. This formation is an important oil and gas play. Since picking, almost nonintermittent prospecting and exploration works have been carried out. A large bulk of heterogeneous material is received and processed, which complement and expand the knowledge of the geological structure and genesis of sediments. The research was carried out by petrographic and lithological methods. As a result, 5 lithotypes were identified according to the ratio of carbonate and terrigenous components and structural and textural features. It was found that the carbonate component prevailed in all the selected lithotypes, which distinguished this formation from other similar sections, where terrigenous rocks predominated. The presence of bioturbation of varying degrees of intensity and the presence of tempestites is characteristic.
东奥伦堡拱状隆起西南部科尔干地层的岩性特征
根据对岩心材料的研究,考虑了东奥伦堡拱形隆起西南部弗拉斯年阶段科尔干地层沉积物的岩性特征。该地层是重要的油气区。自开采以来,几乎不间断地开展了探矿和勘探工作。收到并处理了大量异质材料,补充并扩大了对地质结构和沉积物成因的了解。研究是通过岩石学和岩相学方法进行的。结果,根据碳酸盐成分和陆相成分的比例以及结构和纹理特征,确定了 5 种岩石类型。研究发现,在所有选定的岩型中,碳酸盐成分占主导地位,这使该岩层有别于其他类似岩层,后者以土著岩石为主。不同程度的生物扰动和天风化岩的存在是其特征。
