摘　　要：储层综合评价研究是地学中油气资源勘探开发研究的重要部分。储层是油气聚集的场所,储层的综合评价实际上是考虑孔隙度、渗透率和沉积环境等的多因素综合分析。利用GIS的强大的空间分析和图形可视化功能,通过各单因素间的叠加分析,可以提高储层评价效率,增加评价结果的真实性、客观性和表现力,为油气勘探决策提供更可靠的依据。介绍了基于GIS的储层综合评价系统设计和开发的基本思路和设计方法,并给出了一个研究实例。Comprehensive evaluation of reservoir researching is a critical aspect of the petroleum and oil exploration researching. Comprehensive evaluation of reservoir is a kind of multi-factor analysis which takes the permeability, porosity, sedimentary environment and some other factors into consideration. Geographic information system is a kind of spatial database system which used to getting, saving, selecting, analyzing and displaying spatial data. GIS% capabilities in spatial analyzing and graphics visualization are very strong .Using the excellent capabilities of GIS, some single factors of reservoir can be spatially joined to create a multi-factors map. In this way, we can realize the integration of basical data inputing and management, muli-factor analysis and result displaying and outputting. It can also impove the efficiency, truthfulness and objectivity of the assessment. In other side, we can reduce some mistakes which are made by man, so can provide relatively reliable reference for determining which areas are most favorable for exploration. This system is developed in the basic environment of Visual Basic6.0, and use Supermap Objects comGIS as the basical platform for realizing the system. In other word, it is an example of reservoir comprehensive assessment based on GIS.
