Experimental Study of Decay Conditions of Organic Matter and its Significant for Immature Oil Generation

In order to study the decay conditions of organic matter in early stage of sedimentation, 23 samples were simulated in a low temperature (80°C), long-term condition (>1 year). Gypsum, metals, salt, were used as catalysts, and coniferae and algae were used as original source of oil generation in this experiment. The results indicate that coniferae and algae can produce oil in briny conditions in a very short time (<30 days), and oil was expelled from organic matter at different times dependent on the simulation conditions.
