| Abstract: | A sequence stratigraphic framework of the Cretaceous System in the Huhehu Depression is established in this paper on the basis of comprehensive integration of seismic data,drill cores and well log data.The Cretaceous System in the Huhehu Depression is divided in to three first-order sequences(TSq1-TSq3),five second-order sequences(Ⅰ-Ⅴ),and eight third-order sequences(Sq1-Sq8).Sedimentary facies such as alluvial fan,fan delta,braided river delta,sublacustrine fan,and lake deposition are recognized.Alluvial fan sedimentary system mainly occurs in Sq1 sequence.Fan delta sedimentary system mainly occurs in the steep slope zone of each sequence,and especially in Sq2 sequence.Braided river delta sedimentary system is found in the gentle slope belt of Sq3,Sq4,and Sq5 sequences.Sublacustrine fan sedimentary system occurs in the depression belt of Sq2 and Sq4 sequences.Sedimentary system evolution was controlled by paleostructures and palaeogeomorphology.Cretaceous sand bodies in the southern Huhehu Depression are important in the exploration of this area. |
