摘要
Based on the theory of high accuracy sequence stratigraphy, this paper reconstructs the sublayer units deposition model of the Putaohua oil layer group PⅠ332a-PⅠ11 thin layer of Yaojia Formation 1st section from Xingshugang area of Daqing Changyuan in Songliao Basin, which comprehensively uses various data such as core analysis, seismic data, well logs and analysis test data. The analysis suggests that there is a "panting uplift action" in Xingbei oilfield, which is the internal dynamic factor of meandering composite belt swings regularly.
