摘要
This paper discusses the reservoir modeling technology used in the Chang 63 research of Heshui area in Ordos basin.According to drilling and core analyses and synthetically using the various facies characteristics,such as palaeontologics characteristics,deposition textures,and structure features,this paper points out that the study area belongs to the braided delta front,and analyses the four kinds of sedimentary mirofacies.On the basis,structural model and sedimentary microfacies model are builded by stochastic technology.3D physical model is builded by lots of indicators.The refined characteristics of such physical parameters as porosity and permeability in 3D area were described by this way.The modeling results show that 3D modeling can show the facts better,and it can provide a reliable basis for oil pool digital simulation,residual oil prediction,adjustment and exploitation.
