Modeling for Fan Delta Reservoir in Dujiatai,North of Huanxiling Oilfield
辽河盆地欢喜岭油田欢北杜家台油藏扇三角洲储层地质建模及其应用效果

The reservoir of Dujiatai in the north of Huanxiling Oilfield is of low porosity, low permeability and high heterogeneity. The characteristics of the reservoir and the microfacies in the study area was analyzed and researched. The characteristics of the microfacies, including underwater channel, underwater interfluve, debouch bar and sheet sand, were analyzed in the area. The microfacies model and the reservoir model of the study area were built up by using fine grid and lots of indicators in three target blocks. The results show that, under the control of the facies model, the reservoir model can show the underground facts better, and the model is fit for the work of developing the remaining oil.
