Abstract: Based on such features of Tarim Basin as miltiple oil sources, polycycle and multistage hydrocarbon generation, by means of the analyzing method of static association and dynamic evolution of the pathway system in the view of systematic and dynamic hydrocarbon reservoir formation, the pathway systems, according to the history of tectonic development and the process of the reservoir formation, are divided into the midlate Caledonian model which is a restrained horizontal direction network transportation system, HercynianIndoChines model which is an unrestrained network transportation system and YanshanHimalayan model which is a patially restrained horizontal direction network transportation system. The pathway system of the typical Lunnan, Lunxi and Tahe reservoirs are taken as cases to study, and the relation between the pathway system and the law of reservoir formation at Akekule salience, Tarim Basin is analyzed, the process of complicated hydrocarbon migration at the Salience, i,e., the law of oil and gas accumulation, is recognized, which provides a theoridic mode for exploring hydrocarbon areas.

Key words: Akekule salience, the pathway system, Lunnan oil field, Tarim Basin
