COMPREHENSIVE EVALUATION OF RESERVOIRS BASED ON THE FUNCTIONS OF GIS SPATIAL ANALYSIS

The conceptual principles and developments of Geographic Information System (GIS) are introduced briefly in this paper. The features of geological information of hydrocarbon reservoirs and the advantages of reservoir evaluation using GIS are also discussed. By means of establishment of database of reservoir comprehensive evaluation and analysis using the GIS functions of characteristic pick-up and combination, the useful characteristic information on reservoir evaluation, such as oilfield area data, geologic data, physical geography, and test can be obtained. Reservoir comprehensive evaluation can be done by right of pertinence analysis of reservoirs using the overlay analysis of GIS.
