摘要
The hydrocarbon generation characteristics of marine shale kerogen from the Middle Ordovician Pingliang Formation were studied in this paper by simulation experiments based on Rock-Eval pyrolysis at three different heating rates.Combined with the patent software(Kinetics),variation in the yield of thermally generated hydrocarbon(S2) with pyrolysis temperature was used to calculate the kinetic parameters of petroleum generation in open system.The result of kinetic simulation is in agreement with the experimental data,indicating that experimental results can be extrapolated to actual geological process.
