%X The research on tectonics evolution and petroleum geology of Lishui-Jiaojiang sag in the East China Sea shelf basin shows that Lishui-Jiaojiang sag could be divided to be south area and north area by second-order transfer zones from south to north, and four belt s could be seen clearly from west to east. The central area is typical sag with fault in the east and overlap in the west. Affected by repetitious tectonic events, a mass of faults and kinds of structural trap emerged. The periods of tectonic form action and its evolution consist of four periods of time, the embryo mold of the sag-rift basin-emerged in the united effect of three plates (the Pacific plate, the Eurasia Plate and the Kula Plate), then as the change of direction of the Pacific plate and the back-arc extension resulted by the durative plate seduction of the Pacific plate, the sag was changed to a fault basin, while several territorial unabiding uplifts took place, as a result, some stratums which formed formerly were denudated, so territorial unconformity surface appeared. The tectonic evolution features of the basins resulted in dynamic conditions for the hydrocarbon accumulation, on the other hand, transformed or destroyed the space-time distribution of dynamic and static stage geological element s and their match relations. While the mail faults in the sag also controlled the development and distribution of source rock and accelerated the vertical migration of oil, at the same time, the accumulation of oil and gas was also effected by them.
