Genetic Aspects Of Oil-and-gas Formation, Sulfur And Metal Contents Of Oil

摘要

The possibility of polygenous formation of oil-and-gas systems has become the dominant thinking recently. The catalytic synthesis based on CO and H_2 is accepted to be the most probable way of formation of the abiogenous component of oil. This opinion is substantiated by the presence of certain quantities of these gases in endogenous fluids and by the proved possibility of producing hydrocarbons of different types. This approach explains neither the reasons for the appearance of heteroatoms (S, V, Ni, etc.) in oil nor the observed direct correlations between concentrations of each heteroatom and such values of oils as the content of aromatic structures, resinous asphaltenic components, the condensed state of oil systems and their reserves. Furthermore, other components (CH_4, S, and metals) in the deep fluids that are able to enter into reactions and of which one (S) is a toxin suppressing hydra-tion of carbon oxides are not taken into account.
