In order to predict the effective reservoir sandstone distribution of He8 Member, Su6 infilling well experimental area, Ordos basin, a reservoir geological model is built with the geological, logging and production data, including 4 submodels (formation skeleton model, structure model, sedimentation model and property model). According to the geological model, the depositional environment of He8 Member, Su6 infilling well experimental area is fluvial facies, the sandstone microfacies, which is composed of channel, point bar and channel bar. The sandstone with lace shape extends from north to south. The reservoir with porosity 3%-15% and permeability (0.1-2)×10-3μm2 is typically low porosity and low permeability. Using the geological model, the space distribution of the effective sandstone of the experiment area can be predicted directly and accordingly provides the geological basis for the gas field development.
Key words： Reservoir modeling; Low-permeability; Effective reservoir; Su6 area; Ordos basin.
