Abstract

Heating and pressing simulation experiments of typical source rocks(type I-II_1,II_2 and III) of Zhu 1 depression are performed in the closed vacuum system.Peak stages of oil and gas generation and their generating ratios in different thermal evolvement stages have been studied.Also discussing modes of hydrocarbon generation and expellation,oil and gas affinity,hydrocarbon generation potential and TOC recovery coefficients of different source rocks in the different stages.The results of this paper provided.

Key words： Heating and pressing simulation experiment; Hydrocarbon generation and expellation mode; TOC recovery coefficient; Source rock; Pear river mouth basin.
