Abstract:

 For the purpose of building a digital model linking the reservoir geology and reservoir development,the concept of digital reservoir based on GIS （Geographical Information System）is discussed.A GIS based digital reservoir is proposed to display gelogical study and carry out development dynamic analysis. A framework of digital reservoir based on 2D GIS is presented, and the feasibility of integrating reservoir modeling and simulation using DEM（Digital Elevation Model） and 3D block grid together with other models to built digital reservoir system is analyzed. The functionalities of 3D GIS based digital reservoir model are also discussed.

Key words: digital reservoir, digital oilfield, reservoir management, geographical information system（GIS）
