Take the example of the PⅠ3 sublayers of the Twelve-section in the Xing region of the Daqing oilfield, in this paper, to analysis depositional patterns of reservoirs. To make a effectively reasonable development adjustment, correlation methods were raised, which are well-well、plane well net and identical formation cause boundary remotion according to fluvial sedimentology and high resolution sequence stratigraphy new theory, in order to solve the difficult question of sublayers’ unification and correlation in complicated fluvial-delta strata. To distinguishe one subfacies and seven microfacies, and then to establish logging microfacies model. The single sand body of identical formation cause is delibrately depicted. Finally, to establish three reservoir depositional patterns, which are large-scale compound type channel sandbody, medium-sized distributary channel sandbody, small size distributary channel sandbody, respectively.
