The Formation, Evolution And Reservoir-controlling Mechanism Of Relay Zone In In Structure Zone Of Da Bei-Ke Lasu

Dabei-Kelasu tectonic zone transition zone is Kuche depression internal fault and fracture system between the important tectonic deformation, is an important oil-bearing structure. This paper summarizes and analyzes the domestic and foreign scholars to the conversion zone concept as well as the domestic and foreign scholars for transition zone classification evolution, thought transformation belt is a tectonic deformation zone of specific structural layers in regulating stress on space-time distribution of tectonic stress difference, there is difference in conservation, or structural rule change.The thought transformation belt formation mechanism mainly has two kinds:fault segmentation extended growth mechanism and the differential mechanism. Through the analysis that the North-the Kelasu tectonic zone in the presence of2types conversion: side slope break type transformation belt and tear fault transfer zone. On the basis of this, combined with the conversion zone identification technology, identify research zone transition zone distribution, and explicit conversion belt level and distribution characteristics.By breaking away from the backstripping technique in geological history, restoration of fracture and transformation belt distribution, determining the conversion with the law of formation and evolution; according to the transfer belt forms evolution and sedimentary facies matching relationship, with obvious that conversion control of sand into the basin and channel.Finally, according to the transition zone and "storage-carry" relationship with reservoir controlling mechanism, analysis and conversionIn short, the transformation belt forming oil and gas accumulation is closely related, it in the petroleum geology exploration plays an important role in the future exploration, is the key in.
