文摘

The variations of fluorescence color, homogenization temperature and internal pressure during oil cracking were modelled. The degree of oil cracking can be estimated by the degree of pyrobitumen filling of oil inclusions (Fvpy). Pyrobitumen that forms from oil cracking shows consistent Fvpy in the same fluid inclusion assemblage. Only normal pressure or underpressure occur in lower degrees of oil cracking. Overpressure and even lithostatic pressure occur in higher degrees of oil cracking.
