摘要
Sequence stratigraphic studies have been carried out in the Carboniferous Donghe sandstones in the Tarim Basin. An integrated technique for sequence stratigraphic interpretation has been discussed. The technique can be used to identify sequence boundaries and establish stratigraphic frameworks. Through field outcrop observation, drilling data analyses and seismic profile interpretation, the authors have identified 6 sequences in the Carboniferous. The Donghe sandstone sequence in Juema-Saike region is a diachronous lithostratigraphic unit including 3 sequences: C-SQ1, C-SQ2 and C-SQ3. The main part of the sequence is equivalent to TST. The sandstones consist of coastal onlap deposits and are the key targets for future explorations.
