The fault occurrence, fracture combination and structural patterns of basins were analyzed, and a great oblique transition zone was identified in the central Huanghua Depression. The transition zone was mainly developed in the Paleogene and showed a range of syndepositional anticline with various amplitudes which stretched a distance over 70 km along its strike. The transition zone was constructed by two groups of overlapped antithetic faults. The transition zone was characterized by abundant sandbody reservoirs and two favorable traps of faulted anticline and onlap pinching out in the Paleogene. It is verified that the transition zone is an important hydrocarbon accumulation belt.
