    A material source system analysis of the 3rd Member of Ziniquanzi Formation in the central part of southern margin of Junggar Basin

    • Abstract:In the central part of southern margin of Junggar Basin, the 3rd Member of Ziniquanzi Formation(E1-2z3)characterized by fine accumulation properties is an important oil and gas exploration horizon. There exists intimate relationship between the reservoir distribution and the material sources, and hence the material source system analysis is a key to hydrocarbon exploration. In this paper, an analysis of heavy minerals and a division of their assemblages were carried out for well data and field sections according to their type, quantity variation and distribution in the study area. In addition, statistics of sand and conglomerate thicknesses as well as their spatial distribution characteristics were studied. It is found that there exist four material source systems in the 3rd Member of Ziniquanzi Formation in the central part of southern margin of Junggar Basin. The authors' study of the depositional systems and reservoir prediction in this area is of great significance for further researches.
