摘要
Daqing Placanticline was located in the central sag of Songliao Basin. Upper Putaohua oilbearing layer (PI) belongs to a part of the 3rd Member of Qingshankou Formation and 1st Member of Yaojia Formation. Based on the framework of high-resolution sequence stratigraphy, several sections are established. Much bigger thickness of stratigrahpy and more short-term base level cycles are found in southern of study area. According to the analysis of these high-dense sections, three kinds of stratigraphy overriding models are proposed, includes active progradation model in low accommodation condition, forcing progradation model in lowest accommodation condition and congruence model of progradation and erosion. These stratigraphy overriding models are the main facts causing the differences in stratigraphic thickness and number of shortterm cycles.
