The surface structures were projected to depths by previous correlations between long and deep faults, with all layers and deformation factors defined. The mean deformation factor （Ds） is 0.12 unit/km^3 in the upper layer, 0.012 unit/km^3 in the intermediate layer, and 0.007 unit/km^3 in the lower layer of the 3-D ASFA neotectonic model. Ds allows correlation of the three distinguished layers with theological bodies that differ in their potential for accumulating elastic energy. 3-D modeling can be used as a methodological approach to projections in seismic prone areas such as the Krasnoyarsk region, for earthquake-hazard monitoring.展开更多

But development of oil and gas reservoir has its particularity, development and management GIS of oil and gas reservoir should use the other techniques to extend the forms of representation to make up the shortages of GIS in representation. The development and management GIS of oil and gas reservoir will be perfect besides the basic functions of GIS. This paper expatiates how to use other techniques to extend GIS in development and management of oil and gas reservoir mainly from productive dynamic curve of well, layers of map piling up, 3 D geological model and replaying maps, etc. Through extended GIS in development and management of oil and gas reservoir, the forms of representation of geological information are enriched, representations of information are more direct and visual, spatial descriptive ability and forms of representation of GIS are built up and the single information system will be developed into a management and decision making system.展开更多
