摘要
Bring up a classification scheme suit for analyzing beach bars sedimentary system basin based on Upper Es4 in Huimin and Dongying depressions.Through comparison and analysis of beach bars sedimentary characteristics,the sedimentary characteristics and distribution model of beach bars are controlled by accommodation space,lake level fluctuation,ancient shoreline change,sediment dynamics transfer zone,provenance,palaeogeomorphology and strata gradient.Sedimentary terrain differences caused by tectonic movement,provenance and sediment dynamics transfer zones play a major role in the effective factors.Two kinds of spatial distribution model about beach and bar sedimentary facies are summarized,a model for the facies in single fault overlap and middle rise of Dongying Depression,and another model for the facies in centralrise of Huimin Depression.
