摘　　要：陆相断陷盆地是世界上重要的含油气盆地类型之一,我国东部大陆及沿海分布着约230个各具特色的中、新生代陆相断陷盆地,是世界上最大的陆相含油气盆地集中分布区。陆相断陷盆地在其沉积演化过程中,断裂构造对断陷湖盆内沉积体系和砂体发育具有明显的控制作用。第一,对断陷盆地而言,盆缘断裂控制着盆地的样式。第二,盆缘断裂控制着断陷湖盆内坡折断裂带的形成,为沉积提供了潜在的空间和充填动力。第三,影响着物源的碎屑供给,进而控制着沉积体系类型,砂体成因类型及时空演化和分布特征。所以,深入研究陆相断陷湖盆断裂构造,对沉积体系及砂体的控制作用具有重要的实际意义和理论价值。Continental facies downfaulted basin is one type of the important oil-gas contain basin in the world.About 230 unique feature downfaulted basin in Mesozoic and kainozoc era distribute in the east continent and alongshore in China,which is the best concentric distribution area of continental facies oil-gas contain basin in the world.During the sedimentary evolution of the continental facies downfaulted basin,abruption tectonic control obviously the sedimentary body system and the development of the sand.First of all,as being the downfaulted basin,the abruption of margin of the basin controls the pattern of the basin.Second,the abruption of margin of the basin controls the formation of the sloped breakdown in the abruption belt of the downfaulted lake basin,which supplies the potential area and filled power.Uhird,the abruption of margin of the basin influences the supply of the terrigenous chippings and controls the mode of the sedimentary body system,mode of the sand origin,area and temporal hour evolution and characters of distribution.Therefore,it is of very important practice meaning and theory value for research deeply the control action of the abruption tectonic of continental facies downfaulted lake basin to the sedimentary body system and sand distribution.
