The Qigu Formation reservoir of Che-2 well block in the Junggar Basin is mainly of braided river deposits.Lithology

lithofacies and reservoir structure models were established for the Qigu Formation.The interpolation between wells and stochastic simulation were conducted for each facies according to the quantitative distribution of reservoir parameters in different sedimentary facies.The quality and speed of reservoir characterization were improved

realizing accurate description of reservoir features in respects of structure

sedimentation

physical property and oil-bearing property.The study results lay a solid foundation for the future numerical simulation in this area.
