The Donghetang Formation is the important exploratory formation in the Qunkuqiake structure zone, Tarim Basin. The dolomite and ankerite cements are extensive in the sandstones. The dolomite cement developed in the sandstones during early diagenetic stage and their content in the sandstones increase respectively from east to west. The formation sequence of ankerite cement was later than that of petroleum migration in the reservoir. The result of the study provides new evidences for the westward direction of petroleum migration in the reservoir
