摘要
After a long time’s thermal evolvement,marine sapropelic source rocks in Cambrian-middle Ordovician,mainly type I kerogen,had underwent complicated periods of maturation in a high overmature stage,and generated oil and gas in time history.With researches of predecessors,palaeogeothermal in the Eastern Tarim Basin can be divided into five phases and two zones.Used solid bitumen in the source rocks to measure equivalent vitrinite reflectance and BasinMod1-D software,we inversed Ro so as to get the evolution extent of key periods.Meanwhile,thermal evolution types of study area can be divided into three ones By the process remolding.Finally,with the successive gas generation and theory of hydrocarbon getting from kerogen,we draw the line of favorable generation area in the Eastern Tarim Basin.
