Abstract: A ccording to the hydrous py roly sis results of immature source rock from O rdovician sys tem, average ap- parent activation energies and frequency fact ors of kerosene from t he Lower Paleozoic at different evaluation stages are calculated.I t indicates that the w hole evolution coures is not in accord w ith the firs t order reaction, but different evolut ion stag s are in accord wi th the first order react ion.T hese calculation results have impo rt anreference value to basin simulation and resource evaluation of source rock from t he Low er P alaeozoic and M id- dle nd U pper Proterozozic.
