Abstract: Based on the outcrop,borehole,logging and seismic data,the Donghe Sandstone in Tabei Uplift is defined as a thirdsequence stratigraphy.This sequence has an obvious sedimentary cycle from transgression to regression,and can be divided into transgressive system tract and highstand system tract.The major lithology of the Donghe Sandstone is detritus quartz sandstone which has a high composition and texture maturity.It develops cross bedding,parallel bedding,swash bedding,massive bedding and bioturbate structure.According to the progradational seismic facies and the core observation,wavedominated delta depositional system is developed in well Donghe 20,Saike Uplift and well Cao 4.

Key words: Donghe Sandstone, sedimentary facies, wavedominated delta, Tabei Uplift, sequence stratigraphy 
