摘　　要：三江盆地为大型中新生代叠合盆地,应用最新资料,从区域地质、盆地构造、油气勘探方向等方面进行了探讨,指出盆地经历前陆、准克拉通等6个演化阶段,形成了3坳2隆多构造层错置叠合的复杂构造格局,并控制了形成油气的地质条件,预测普阳坳陷为有利生烃区,早白垩世末期形成的构造为有利含油气区带。Sanjiang Basin is a large mid-Caenozoic coincidence basin,the latest data are used to study the regional geology,basin structure,and the direction of oil and gas exploration.It is pointed out that the basin experiences 6 evolutional periods,such as front land period and Cratonic period,etc,a complicated structural framework of multi-structural coincidence with 3 depressions and 2 uplifts is formed,by which the geologic conditions for hydrocarbon accumulation are controlled,Puyang Depression is a predicted beneficial area of hydrocarbon genesis,while the structure formed at the late period of early Cretaceous period is a beneficial oil-gas-bearing area.
