基于GIS的数字油藏模型探讨

为了建立一个能沟通油藏地质和油藏开发的数字化模型，从空间数据信息的角度对数字油藏的实现途径进行了研究，提出在地理信息系统（GIS： Geographical Information System）基础上建立数字油藏模型，并在统一的GIS平台上进行油藏地质研究成果展示和开发动态分析。给出基于二维GIS数据模型的数字油藏的基本框架，并讨论了三维GIS数据模型与数字油藏的关系，提出用多层数字高程模型（DEM： Digital Elevation Model）和三维栅格等多种模型联合建立三维GIS数字油藏模块的实现方法，最后指出了GIS平台下进行数字油藏应用与油藏开发分析设计的前景。

Study of Digital Reservoir Model Based on GIS

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.
