Identification of Sedimentary Microfacies in Retrograding Alluvial Fan of Badaowan Formation in Dishuiquan Oilfield in Eastern Junggar Basin
详细信息   
摘要

The studied results of regional geology, seismic,  logging and core analysis data in the J1b1 sedimentary microfacies of the Badaowan Formation in the Di-12 wellblock of Dishuiquan oilfield located in slope area of eastern Junggar Basin show that the J1b1 is alluvial fan deposit,  which could be further divided into 3 sub-facies of the top fan, middle fan, edge fan and 8 microfacies. The vertical variation of lithology and lithofacies reflect that the target zone with the backfill characteristic on the Carboniferous is the earliest low-stand system tract of the Jurassic in this study area. The sedimentary environment of the J1b1 is transited from the top,  middle fans up to the edge fan,  showing such a period is in retrograding alluvial fan deposit under transgression environment.
