| الوصف: | Based on the study of the molecular mass distribution in n-alkanes of bitumen of the Semilukskian horizon, the presence of migrational hydrocarbons was revealed in them with a different generation source. The results obtained on the basis of the molecular mass distribution are in good agreement with the group composition of bitumen, as well as with the results of gass liquid chromatography (bitumen and oil) and pyrolytic studies. The high convergence of the results obtained by different methods confirms the expediency of using the molecular mass distribution method for estimating the migration component in rocks of different productive horizons and in shale strata. The dominant process in the formation of initial organic matter of the Semilukskian horizon was the active bacterial environment, caused by anoxid conditions with hydrogen sulfide contamination of the sedimentation basin. The occurrence of anoxic environments with hydrogen sulphide contamination was most likely due to the periodic activation of volcanic activity and other endogenous processes that were regional in nature and took place on a significant area of the continental slope of the ancient platform. The existence of anoxidic environments in different parts of the sedimentation basin varied in intensity, duration, and periodicity of occurrence. The area of their distribution in the Sargaevskian-Mendymskian time was more regional in nature. Then, due to changes in the intensity of endogenous processes, it narrowed. The continued periodic occurrence of anoxidic events along deep faults led to the formation of intra-formation deflections of the Kama-Kinel system. |
