Abstract: Fan delta are well developed in Xing'anling Group, Block Bei-14 of Suderte oilfield, with materials sourced mainly from south and southeast. On the basis of log-curve facies and core sedimentary model, structural model has been established on well seismic tie, and microfacies model has been constructed on the basis of structural model by using sequential indicator simulation method. Then, on the basis of the sedimentary facies types, with variate difference function, the petrophysical parameters are simulated by using sequential gauss simulation under the control of sedimentary microfacies modeling. Posterior precision analysis shows that the facies controlled reservoir property modeling can reduce the uncertainty of random simulation, and improve the precision of reservoir prediction.
