The Characteristics Of Tectonic Evolution And Its Control On Hydrocarbon In Its Southern And The Xingshugang Tectonic Belt

In this paper, based on the 3D seismic data, first of all, on the basis of Putaohua oil layer of edge top five oil production company interface elevation, the fixed endpoints elevation, fixed separation of dip strata distribution and accumulated structural relief of fixed interface separation such indicators as fine division of tectonic units. Secondly, the systematic analysis of fracture development geometry features, in combination with the structural evolution section and fault growth index, clear fracture activity time. In the end, combined with the reservoir distribution, this paper discusses tectonic units, the fault characteristics and fault-relations of configuration of the control action of hydrocarbon distribution.Research results show that:(1) construct things zoning controls the feature of oil moisture, construct the north and the south block controls the oil and gas enrichment degree and the oil-water enveloping surface, structure wing steep slow control the oil-water dynamic capacity difference.(2) growth of fault block is a major mechanism of forming the broken, control the formation of reverse fault footwall circle and synthetic fault disk broken ring; At the same time, the different fracture tectonic belt control the oil and gas enrichment regularity, the difference of the fracture edge micro structure control the oil and gas enrichment.(3) the putaohua oil layer in long-term activity faults control the depression layer distribution law of river channel sand body, fault- relations of configuration control of the oil and gas enrichment.
