Abstract: From the view-point of geomechanies,by an application of the result of comprehensive analysis of the results from structural geological,geomor-phological,and hydraulic geological studies,combined with those from laboratery mechanical simultaneous studies and those from seismic and exploratory drilling,this paper discusses the regularities of the faulted deformation charac-teristics of the geotectonic faulting and the regularitics of oil and gas enrichment in various geotectonic system(or stractural blocks).It is pointed out that in those strongly compressional deformed structural systems those relatively gentle regions should be explorated first;while those regions with relatively concentrated stress should be explorated first in the relatively weakly deformed structural systems.Thus commercial gas reservoirs may be discovered.
