Combining the spatial distribution characteristics of oil and gas reservoirs in Sujiatun area of Lishu rift， the authors study the control action of hydrocarbon source rock- ， trap- ， conducting-and preservation conditions to hydrocarbon accumulation． The research shows that the tectonic and sedimentary evolution characteristics control the spatial distribution of the quality source and reservoir; tectonic setting and different conducting conditions con- trol the migration direction，and result in obvious difference among oil gas traps at different tectonic position． And， the various differential accumulation modes work together to lead to traps capture and preserve oil and gas sectional- ly，and control the plane enrichment degree of oil and gas．
