Structural styles control the deposition and oil-gas accumulation. According to analysis of the charac- teristics of basin structure, tectonic evolution, seismic data and different zone oil-gas geological model in Jiyang depression, the conclusions are that, there are seven secondary structural styles including tilted faulted-block, slide faulted-ramp, buried hill draping, gravitative antiform and diapir structure in the basin. Different structural belt is formed of different superimposed structural styles. In the rift period, the steep slope zone evolved from the early plate faults into late slide block or rollover anticline, the central uplift belt is formed of late anticline or half anticline overlaying on the early subsag, the gentle slope belt is composed of different types of early and late over- lying faulted block, the bump belt is formed of buried hill and draping anticline. Differences of tectonic styles de- velopment control the oil-gas accumulation differences in different structural zones. Oil-gas enrich in the bump belt, the central uplift belt of diapiric anticline controlling and the steep slope of main control fault with a high evolution degree.
