摘要
Using data from cores,well logging,seismic and core enperiment,the sequence stratigraphy analysis and sedimentary facies identification of the Paleocene of Haian Depression in Subei Basin are conducted.This paper shows that the Haian Depression had undergone four tectonic uplift movements(Yizheng movement,Wubao movement,Zhenwu movement and Sanduo movement) during the basin fault-depression stage from Taizhou Formation to Sanduo Formation periods,and 3 secondary-order sequences were formed.The differences of sedimentary characteristics and the space location relationship of the system tracts cause the different matching relationship of favorable source-reservoir-cap assemblages.
