摘　　要：本文从地质力学观点出发,应用构造地质学、地貌学,水文地质学等综合分析的新方法,结合力学模拟试验、地震和钻探成果,从应力分布及构造断裂形变特征,探讨了川东不同构造体系(或构造区块)应力驱动和油气富集规律。指出了在强烈挤压形变的构造体系中,侧重于勘探应力相对舒缓地带;在构造形变微弱的体系中,侧重于勘探应力相对集中地带,才有利于钻获工业性气藏。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.
