为了能够对油藏进行更为精确的描述与分析,文中对在GASOR和Petrel软件中常用的输入数据进行分析,提出了在油藏建模过程中建立空间数据模型的理论,在建模的初始阶段将不同数据分类成不同作用的空间数据模型并对其数据格式做出整理和分类,这在油藏建模系统的三维显示中清晰的展现了空间数据模型的优势,对油藏建模后期的数据转换和构造模型的建立有很重要的意义。 In order to be able to describe and analyze reservoirs more accurately, the input data commonly used in GASOR and Petrel software are analyzed in this paper. The theory of building spatial data model in reservoir modeling is proposed. At the initial stage of modeling Stage to classify different data into different kinds of spatial data models and to organize and classify their data formats. This clearly demonstrates the advantages of the spatial data model in the 3D display of the reservoir modeling system, The data conversion and the construction of the model is of great significance.
