Kinetic study of the hydrocarbon generation from marine carbonate source rocks characterization of products of gas and liquid hydrocarbon

Abstract

The kinetic parameters of hydrocarbon generation from the marine carbonate source rocks were determined and calibrated through kinetic simulating experiment. The kinetic parameters of hydrocarbon generation then were extrapolated to geological condition by using the relative software. The result shows that gaseous hydrocarbons (C1, C2, C3, C4–5) were generated in condition of 150°C < T < 220°C (1.0%<R o <3.0%). Light hydrocarbons (C6–13) and heavy hydrocarbons (C13 +) were generated in condition of 100 °C <T<170 °C (0.5%<R o<1.5%). A quantitative reference to examine the natural evolution of hydrocarbon of marine carbonate source rocks can be established through the results. It also provides a new method for evaluating the highly mature marine carbonate source rock more reasonably.
