The classification and significance of carboniferous stratigraphic sequence in jimushaer sag, eastern part of junggar basin

Jimushaer sag is the main Oil and Gas unit in the eastern part of Junggar Basin,it shows good exploration prospect in Carboniferous formation by accessing to industrial oil flow of well Ji15,We can find a clear overlap and trunction featrues by the detailed study of the seismic reflection characteristics of the Carboniferous in the area,and those characteristic can be carried out a very good comparison that used for strata correlation of the Carboniferous in the area.Based on the above,we classify the Bashan Formation in Upper Carboniferous and Low Carboniferous,then we divide the tectonic units of Carboniferous in the area.These results will play an important role in the exploration of Carboniferous
