Abstract

In the southern part of the Luliang Uplift Shixi Area of the Junggar Basin,the Xishanyao Formation(J2x)offers favorable oil and gas prospects,but studies on its tectono-sedimentary system have been relatively limited.Thus, based on well logs,seismic data,core samples,employing Dionisos forward modeling and the sediment distribution related to the Chepaizi-Mosuowan Paleo-Uplift and its margins were characterized.The results showed that during J2x deposition,the Chepaizi-Mosuowan Paleo-Uplift was a low-amplitude NE-SW trending anticline that underwent rapid uplift during the J2x2,J2x3 and J2x4 stages,producing stratigraphic overlap and deposition missing.A dual provenance sedimentary system from the north and northeast gradually interfingered and merged into a single deltaic deposition system in the J2x3 and J2x4,developing various sub-facies such as underwater distributary channels,inter-distributary bays and mouth bars.Variations in the uplift rate of the Chepaizi-Mosuowan Paleo-Uplift controlled the coupling between accommodation space and sediment supply,thereby influencing sediment distribution;the coarse-grained fan deposits derived from this source constituted favorable reservoir sand body.This study provides valuable guidance for research on the J2x sedimentary system in the Shixi Area.
