摘要
The tectonic attributes and controlling factors were studied through the analysis of high-precision 3D seismic,drilling,core,slice,logging data and the fracture characteristics of main boundary faults and faults inside Maozhou tectonic belt. The results show that Maozhou tectonic belt has the function of adjusting regional tectonic deformation in Paleogene.Maozhou transition zone experiences three evolution stages. Maozhou transition zone not only improves reservoir properties of buried hill,but also controls clastic reservoir distribution in the Paleogene.Hydrocarbon derived from the source rocks of Paleogene matches well with geological factors and geological function relating with Maozhou transition zone reservoir-forming in time and space.Therefore,two reservoir-forming modes of “new bed-generating and old bed-storing” and “self-generating,self-storing and self-sealing” are estabilshed in transition zone.
