涪陵地区焦石坝构造龙马溪组页岩气地质建模

Geological Modeling of Longmaxi Shale Gas in Jiaoshiba,Fuling Area

涪陵地区焦石坝构造龙马溪组页岩储层的岩相及物性在纵横向上均具有较强的非均质性。针对此特征,应用Petrel地质建模软件,建立龙马溪组下段8个小层的构造模型、地层模型、岩相模型及孔隙度与渗透率模型,反映龙马溪组下段页岩厚度的空间展布及页岩气储层岩相和物性的非均质特征。

The lithofacies and physical property of the shale reservoir have strong heterogeneity in different directions in Jiaoshiba of Fuling area. By the methods of 3D seismic interpretation,Petrel software and stochastic modeling,we built structure model,lithofacies model,porosity model and permeability model for 8 thin layers in Longmaxi lower segment to reflect the spatial distribution of shales in Longmaxi lower segment and the permeability of reservoir lithofacies as well as the physical property.
