According to the core, drilling, logging, seismic and combined with the production test and other data, application of high resolution sequence stratigraphy theory, the Daqing oilfield in the ancient 1 block of the oilfield H2 oil layer group is divided into 1 Mid cycle, 10 short-term cycles, 1 blocks of the Daqing oil field, the formation of single sand body level high resolution sequence stratigraphic framework, for the study of the small layer, the connectivity of sand and sand body, as well as the study of sedimentary microfacies provides a very important significance for oil and gas exploration and development.
